Gtk.TreeView ¶

Opens the row so its children are visible.

expand_to_path(path)[source]¶

Parameters:: path (Gtk.TreePath) – path to a row.

Expands the row at path. This will also expand all parent rows of path as necessary.

New in version 2.2.

get_activate_on_single_click()[source]¶

Returns:: True if row-activated will be emitted on a single click
Return type:: bool

Gets the setting set by Gtk.TreeView.set_activate_on_single_click().

New in version 3.8.

get_background_area(path, column)[source]¶

Parameters:

path (Gtk.TreePath or None) – a Gtk.TreePath for the row, or None to get only horizontal coordinates
column (Gtk.TreeViewColumn or None) – a Gtk.TreeViewColumn for the column, or None to get only vertical coordiantes

Returns:

rectangle to fill with cell background rect

Return type:

rect: Gdk.Rectangle

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is None, or points to a node not found in the tree, the y and height fields of the rectangle will be filled with 0. If column is None, the x and width fields will be filled with 0. The returned rectangle is equivalent to the background_area passed to Gtk.CellRenderer.render(). These background areas tile to cover the entire bin window. Contrast with the cell_area, returned by Gtk.TreeView.get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area.

get_bin_window()[source]¶

Returns:: A Gdk.Window, or None when self hasn’t been realized yet.
Return type:: Gdk.Window or None

Returns the window that self renders to. This is used primarily to compare to event->window to confirm that the event on self is on the right window.

get_cell_area(path, column)[source]¶

Parameters:

path (Gtk.TreePath or None) – a Gtk.TreePath for the row, or None to get only horizontal coordinates
column (Gtk.TreeViewColumn or None) – a Gtk.TreeViewColumn for the column, or None to get only vertical coordinates

Returns:

rectangle to fill with cell rect

Return type:

rect: Gdk.Rectangle

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is None, or points to a path not currently displayed, the y and height fields of the rectangle will be filled with 0. If column is None, the x and width fields will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cell_area passed to Gtk.CellRenderer.render(). This function is only valid if self is realized.

get_column(n)[source]¶

Parameters:: n (int) – The position of the column, counting from 0.
Returns:: The Gtk.TreeViewColumn, or None if the position is outside the range of columns.
Return type:: Gtk.TreeViewColumn or None

Gets the Gtk.TreeViewColumn at the given position in the #tree_view.

get_columns()[source]¶

Returns:: A list of Gtk.TreeViewColumn s
Return type:: [Gtk.TreeViewColumn]

Returns a GLib.List of all the Gtk.TreeViewColumn s currently in self. The returned list must be freed with g_list_free ().

get_cursor()[source]¶

Returns:

path:: A pointer to be filled with the current cursor path, or None
focus_column:: A pointer to be filled with the current focus column, or None

Return type:

(path: Gtk.TreePath or None, focus_column: Gtk.TreeViewColumn or None)

Fills in path and focus_column with the current path and focus column. If the cursor isn’t currently set, then path will be None. If no column currently has focus, then focus_column will be None.

The returned Gtk.TreePath must be freed with Gtk.TreePath.free() when you are done with it.

get_dest_row_at_pos(drag_x, drag_y)[source]¶

Parameters:

drag_x (int) – the position to determine the destination row for
drag_y (int) – the position to determine the destination row for

Returns:

None if there is no row at the given position or a tuple containing:

path:: the path of the highlighted row
pos:: the drop position

Return type:

(path: Gtk.TreePath or None, pos: Gtk.TreeViewDropPosition) or None

Determines the destination row for a given position. drag_x and drag_y are expected to be in widget coordinates. This function is only meaningful if self is realized. Therefore this function will always return None if self is not realized or does not have a model.

get_drag_dest_row()[source]¶

Returns:

path:: Return location for the path of the highlighted row, or None.
pos:: Return location for the drop position, or None

Return type:

(path: Gtk.TreePath or None, pos: Gtk.TreeViewDropPosition)

Gets information about the row that is highlighted for feedback.

get_enable_search()[source]¶

Returns:: whether or not to let the user search interactively
Return type:: bool

Return type:: bool

Returns whether hover selection mode is turned on for self.

New in version 2.6.

get_level_indentation()[source]¶

Returns:: the amount of extra indentation for child levels in self. A return value of 0 means that this feature is disabled.
Return type:: int

Returns the amount, in pixels, of extra indentation for child levels in self.

New in version 2.12.

get_model()[source]¶

Returns:: A Gtk.TreeModel, or None if none is currently being used.

get_path_at_pos(x, y)[source]¶

Parameters:

x (int) – The x position to be identified (relative to bin_window).
y (int) – The y position to be identified (relative to bin_window).

Returns:

None if the row doesn’t exist at that coordinates or a tuple containing:

path:: a Gtk.TreePath
column:: a Gtk.TreeViewColumn
cell_x:: the X coordinate relative to the cell
cell_y:: the Y coordinate relative to the cell

Return type:

(path: Gtk.TreePath or None, column: Gtk.TreeViewColumn or None, cell_x: int, cell_y: int) or None

Finds the path at the point (x, y), relative to bin_window coordinates (please see Gtk.TreeView.get_bin_window()). That is, x and y are relative to an events coordinates. x and y must come from an event on the self only where event->window == gtk_tree_view_get_bin_window (). It is primarily for things like popup menus. If path is non-None, then it will be filled with the Gtk.TreePath at that point. This path should be freed with Gtk.TreePath.free(). If column is non-None, then it will be filled with the column at that point. cell_x and cell_y return the coordinates relative to the cell background (i.e. the background_area passed to Gtk.CellRenderer.render()). This function is only meaningful if self is realized. Therefore this function will always return False if self is not realized or does not have a model.

For converting widget coordinates (eg. the ones you get from Gtk.Widget ::query-tooltip), please see Gtk.TreeView.convert_widget_to_bin_window_coords().

get_reorderable()[source]¶

Returns:: True if the tree can be reordered.
Return type:: bool

Retrieves whether the user can reorder the tree via drag-and-drop. See Gtk.TreeView.set_reorderable().

get_rubber_banding()[source]¶

New in version 2.10.

get_rules_hint()[source]¶

Returns:: True if the hint is set
Return type:: bool

Gets the setting set by Gtk.TreeView.set_rules_hint().

Deprecated since version 3.14.

get_search_column()[source]¶

Returns:: the column the interactive search code searches in.
Return type:: int

Gets the column searched on by the interactive search code.

get_search_entry()[source]¶

Returns:: the entry currently in use as search entry.
Return type:: Gtk.Entry

Returns the Gtk.Entry which is currently in use as interactive search entry for self. In case the built-in entry is being used, None will be returned.

New in version 2.10.

get_selection()[source]¶

Returns:: A Gtk.TreeSelection object.
Return type:: Gtk.TreeSelection

Gets the Gtk.TreeSelection associated with self.

get_show_expanders()[source]¶

Return type:: bool

Returns whether or not expanders are drawn in self.

New in version 2.12.

get_tooltip_column()[source]¶

Returns:: the index of the tooltip column that is currently being used, or -1 if this is disabled.
Return type:: int

Returns the column of self’s model which is being used for displaying tooltips on self’s rows.

get_tooltip_context(x, y, keyboard_tip)[source]¶

Parameters:

x (int) – the x coordinate (relative to widget coordinates)
y (int) – the y coordinate (relative to widget coordinates)
keyboard_tip (bool) – whether this is a keyboard tooltip or not

Returns:

whether or not the given tooltip context points to a row.

x:: the x coordinate (relative to widget coordinates)
y:: the y coordinate (relative to widget coordinates)
model:: a pointer to receive a Gtk.TreeModel or None
path:: a pointer to receive a Gtk.TreePath or None
iter:: a pointer to receive a Gtk.TreeIter or None

Return type:

(bool, x: int, y: int, model: Gtk.TreeModel or None, path: Gtk.TreePath, iter: Gtk.TreeIter)

This function is supposed to be used in a Gtk.Widget ::query-tooltip signal handler for Gtk.TreeView. The x, y and keyboard_tip values which are received in the signal handler, should be passed to this function without modification.

The return value indicates whether there is a tree view row at the given coordinates (True) or not (False) for mouse tooltips. For keyboard tooltips the row returned will be the cursor row. When True, then any of model, path and iter which have been provided will be set to point to that row and the corresponding model. x and y will always be converted to be relative to self’s bin_window if keyboard_tooltip is False.

New in version 2.12.

get_vadjustment()[source]¶

Returns:: A Gtk.Adjustment object, or None if none is currently being used.
Return type:: Gtk.Adjustment

Gets the Gtk.Adjustment currently being used for the vertical aspect.

Deprecated since version 3.0: Use Gtk.Scrollable.get_vadjustment()

get_visible_range()[source]¶

Returns:

start_path:: start of region
end_path:: end of region

Return type:

New in version 2.8.

get_visible_rect()[source]¶

Returns:: rectangle to fill
Return type:: visible_rect: Gdk.Rectangle

Fills visible_rect with the currently-visible region of the buffer, in tree coordinates. Convert to bin_window coordinates with Gtk.TreeView.convert_tree_to_bin_window_coords(). Tree coordinates start at 0,0 for row 0 of the tree, and cover the entire scrollable area of the tree.

insert_column(column, position)[source]¶

Parameters:

column (Gtk.TreeViewColumn) – The Gtk.TreeViewColumn to be inserted.
position (int) – The position to insert column in.

Returns:

The number of columns in self after insertion.

Return type:

int

This inserts the column into the self at position. If position is -1, then the column is inserted at the end. If self has “fixed_height” mode enabled, then column must have its “sizing” property set to be Gtk.TreeViewColumnSizing.FIXED.

insert_column_with_attributes(position, title, cell, **kwargs)[source]¶

Parameters:

position (int) – The position to insert the new column in
title (str) – The title to set the header to
cell (Gtk.CellRenderer) – The Gtk.CellRenderer

Creates a new Gtk.TreeViewColumn and inserts it into the self at position. If position is -1, then the newly created column is inserted at the end. The column is initialized with the attributes given. If self has “fixed_height” mode enabled, then the new column will have its sizing property set to be Gtk.TreeViewColumnSizing.FIXED.

insert_column_with_data_func(position, title, cell, func, *data)[source]¶

Parameters:

position (int) – Position to insert, -1 for append
title (str) – column title
cell (Gtk.CellRenderer) – cell renderer for column
func (Gtk.TreeCellDataFunc) – function to set attributes of cell renderer
data (object or None) – data for func

Returns:

number of columns in the tree view post-insert

Return type:

int

Convenience function that inserts a new column into the Gtk.TreeView with the given cell renderer and a Gtk.TreeCellDataFunc to set cell renderer attributes (normally using data from the model). See also Gtk.TreeViewColumn.set_cell_data_func(), Gtk.TreeViewColumn.pack_start(). If self has “fixed_height” mode enabled, then the new column will have its “sizing” property set to be Gtk.TreeViewColumnSizing.FIXED.

is_blank_at_pos(x, y)[source]¶

Parameters:

x (int) – The x position to be identified (relative to bin_window)
y (int) – The y position to be identified (relative to bin_window)

Returns:

True if the area at the given coordinates is blank, False otherwise.

path:: A pointer to a Gtk.TreePath pointer to be filled in, or None
column:: A pointer to a Gtk.TreeViewColumn pointer to be filled in, or None
cell_x:: A pointer where the X coordinate relative to the cell can be placed, or None
cell_y:: A pointer where the Y coordinate relative to the cell can be placed, or None

Return type:

(bool, path: Gtk.TreePath or None, column: Gtk.TreeViewColumn or None, cell_x: int, cell_y: int)

Determine whether the point (x, y) in self is blank, that is no cell content nor an expander arrow is drawn at the location. If so, the location can be considered as the background. You might wish to take special action on clicks on the background, such as clearing a current selection, having a custom context menu or starting rubber banding.

The x and y coordinate that are provided must be relative to bin_window coordinates. That is, x and y must come from an event on self where event->window == gtk_tree_view_get_bin_window ().

For converting widget coordinates (eg. the ones you get from Gtk.Widget ::query-tooltip), please see Gtk.TreeView.convert_widget_to_bin_window_coords().

The path, column, cell_x and cell_y arguments will be filled in likewise as for Gtk.TreeView.get_path_at_pos(). Please see Gtk.TreeView.get_path_at_pos() for more information.

New in version 3.0.

is_rubber_banding_active()[source]¶

Returns:: True if a rubber banding operation is currently being done in self.
Return type:: bool

Returns whether a rubber banding operation is currently being done in self.

New in version 2.12.

map_expanded_rows(func, *data)[source]¶

Parameters:

func (Gtk.TreeViewMappingFunc) – A function to be called
data (object or None) – User data to be passed to the function.

Calls func on all expanded rows.

move_column_after(column, base_column)[source]¶

Parameters:

column (Gtk.TreeViewColumn) – The Gtk.TreeViewColumn to be moved.
base_column (Gtk.TreeViewColumn or None) – The Gtk.TreeViewColumn to be moved relative to, or None.

Moves column to be after to base_column. If base_column is None, then column is placed in the first position.

remove_column(column)[source]¶

Parameters:: column (Gtk.TreeViewColumn) – The Gtk.TreeViewColumn to remove.
Returns:: The number of columns in self after removing.
Return type:: int

Removes column from self.

row_activated(path, column)[source]¶

Parameters:

path (Gtk.TreePath) – The Gtk.TreePath to be activated.
column (Gtk.TreeViewColumn) – The Gtk.TreeViewColumn to be activated.

Activates the cell determined by path and column.

row_expanded(path)[source]¶

Parameters:: path (Gtk.TreePath) – A Gtk.TreePath to test expansion state.
Returns:: True if #path is expanded.
Return type:: bool

Returns True if the node pointed to by path is expanded in self.

scroll_to_cell(path, column, use_align, row_align, col_align)[source]¶

Parameters:

path (Gtk.TreePath or None) – The path of the row to move to, or None.
column (Gtk.TreeViewColumn or None) – The Gtk.TreeViewColumn to move horizontally to, or None.
use_align (bool) – whether to use alignment arguments, or False.
row_align (float) – The vertical alignment of the row specified by path.
col_align (float) – The horizontal alignment of the column specified by column.

Moves the alignments of self to the position specified by column and path. If column is None, then no horizontal scrolling occurs. Likewise, if path is None no vertical scrolling occurs. At a minimum, one of column or path need to be non-None. row_align determines where the row is placed, and col_align determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

If use_align is False, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to its current position. If the cell is currently visible on the screen, nothing is done.

This function only works if the model is set, and path is a valid row on the model. If the model changes before the self is realized, the centered path will be modified to reflect this change.

scroll_to_point(tree_x, tree_y)[source]¶

Parameters:

tree_x (int) – X coordinate of new top-left pixel of visible area, or -1
tree_y (int) – Y coordinate of new top-left pixel of visible area, or -1

Scrolls the tree view such that the top-left corner of the visible area is tree_x, tree_y, where tree_x and tree_y are specified in tree coordinates. The self must be realized before this function is called. If it isn’t, you probably want to be using Gtk.TreeView.scroll_to_cell().

If either tree_x or tree_y are -1, then that direction isn’t scrolled.

set_activate_on_single_click(single)[source]¶

Parameters:: single (bool) – True to emit row-activated on a single click

Cause the Gtk.TreeView ::row-activated signal to be emitted on a single click instead of a double click.

New in version 3.8.

set_column_drag_function(func, *user_data)[source]¶

Parameters:

func (Gtk.TreeViewColumnDropFunc or None) – A function to determine which columns are reorderable, or None.
user_data (object or None) – User data to be passed to func, or None

Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to func are: the self, the Gtk.TreeViewColumn being dragged, the two Gtk.TreeViewColumn s determining the drop spot, and user_data. If either of the Gtk.TreeViewColumn arguments for the drop spot are None, then they indicate an edge. If func is set to be None, then self reverts to the default behavior of allowing all columns to be dropped everywhere.

set_cursor(path, focus_column, start_editing)[source]¶

Parameters:

path (Gtk.TreePath) – A Gtk.TreePath
focus_column (Gtk.TreeViewColumn or None) – A Gtk.TreeViewColumn, or None
start_editing (bool) – True if the specified cell should start being edited.

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focus_column is not None, then focus is given to the column specified by it. Additionally, if focus_column is specified, and start_editing is True, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus (self) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

set_cursor_on_cell(path, focus_column, focus_cell, start_editing)[source]¶

Parameters:

path (Gtk.TreePath) – A Gtk.TreePath
focus_column (Gtk.TreeViewColumn or None) – A Gtk.TreeViewColumn, or None
focus_cell (Gtk.CellRenderer or None) – A Gtk.CellRenderer, or None
start_editing (bool) – True if the specified cell should start being edited.

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focus_column is not None, then focus is given to the column specified by it. If focus_column and focus_cell are not None, and focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by focus_cell. Additionally, if focus_column is specified, and start_editing is True, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus (self) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

New in version 2.2.

set_destroy_count_func(func, *data)[source]¶

Parameters:

func (Gtk.TreeDestroyCountFunc or None) – Function to be called when a view row is destroyed, or None
data (object or None) – User data to be passed to func, or None

This function should almost never be used. It is meant for private use by ATK for determining the number of visible children that are removed when the user collapses a row, or a row is deleted.

Deprecated since version 3.4: Accessibility does not need the function anymore.

set_drag_dest_row(path, pos)[source]¶

Parameters:

path (Gtk.TreePath or None) – The path of the row to highlight, or None
pos (Gtk.TreeViewDropPosition) – Specifies whether to drop before, after or into the row

Sets the row that is highlighted for feedback. If path is None, an existing highlight is removed.

set_enable_search(enable_search)[source]¶

Parameters:: enable_search (bool) – True, if the user can search interactively

If enable_search is set, then the user can type in text to search through the tree interactively (this is sometimes called “typeahead find”).

Note that even if this is False, the user can still initiate a search using the “start-interactive-search” key binding.

set_enable_tree_lines(enabled)[source]¶

Parameters:: enabled (bool) – True to enable tree line drawing, False otherwise.

Sets whether to draw lines interconnecting the expanders in self. This does not have any visible effects for lists.

New in version 2.10.

set_expander_column(column)[source]¶

Parameters:: column (Gtk.TreeViewColumn or None) – None, or the column to draw the expander arrow at.

Sets the column to draw the expander arrow at. It must be in self. If column is None, then the expander arrow is always at the first visible column.

If you do not want expander arrow to appear in your tree, set the expander column to a hidden column.

set_fixed_height_mode(enable)[source]¶

Parameters:: enable (bool) – True to enable fixed height mode

Enables or disables the fixed height mode of self. Fixed height mode speeds up Gtk.TreeView by assuming that all rows have the same height. Only enable this option if all rows are the same height and all columns are of type Gtk.TreeViewColumnSizing.FIXED.

New in version 2.6.

set_grid_lines(grid_lines)[source]¶

Parameters:: grid_lines (Gtk.TreeViewGridLines) – a Gtk.TreeViewGridLines value indicating which grid lines to enable.

Sets which grid lines to draw in self.

New in version 2.10.

set_hadjustment(adjustment)[source]¶

Parameters:: adjustment (Gtk.Adjustment or None) – The Gtk.Adjustment to set, or None

Sets the Gtk.Adjustment for the current horizontal aspect.

Deprecated since version 3.0: Use Gtk.Scrollable.set_hadjustment()

set_headers_clickable(setting)[source]¶

Parameters:: setting (bool) – True if the columns are clickable.

Allow the column title buttons to be clicked.

set_headers_visible(headers_visible)[source]¶

Parameters:: headers_visible (bool) – True if the headers are visible

Sets the visibility state of the headers.

set_hover_expand(expand)[source]¶

Parameters:: expand (bool) – True to enable hover selection mode

Enables or disables the hover expansion mode of self. Hover expansion makes rows expand or collapse if the pointer moves over them.

New in version 2.6.

set_hover_selection(hover)[source]¶

Parameters:: hover (bool) – True to enable hover selection mode

Enables or disables the hover selection mode of self. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes Gtk.SelectionMode.SINGLE and Gtk.SelectionMode.BROWSE.

New in version 2.6.

set_level_indentation(indentation)[source]¶

Parameters:: indentation (int) – the amount, in pixels, of extra indentation in self.

Sets the amount of extra indentation for child levels to use in self in addition to the default indentation. The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.

New in version 2.12.

set_model(model)[source]¶

Parameters:: model (Gtk.TreeModel or None) – The model.

Sets the model for a Gtk.TreeView. If the self already has a model set, it will remove it before setting the new model. If model is None, then it will unset the old model.

set_reorderable(reorderable)[source]¶

Parameters:: reorderable (bool) – True, if the tree can be reordered.

This function is a convenience function to allow you to reorder models that support the Gtk.TreeDragSourceIface and the Gtk.TreeDragDestIface. Both Gtk.TreeStore and Gtk.ListStore support these. If reorderable is True, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s Gtk.TreeModel ::row-inserted and Gtk.TreeModel ::row-deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

This function does not give you any degree of control over the order – any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

set_row_separator_func(func, *data)[source]¶

Parameters:

func (Gtk.TreeViewRowSeparatorFunc or None) – a Gtk.TreeViewRowSeparatorFunc
data (object or None) – user data to pass to func, or None

Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is None, no separators are drawn. This is the default value.

New in version 2.6.

set_rubber_banding(enable)[source]¶

Parameters:: enable (bool) – True to enable rubber banding

Enables or disables rubber banding in self. If the selection mode is Gtk.SelectionMode.MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

New in version 2.10.

set_rules_hint(setting)[source]¶

Parameters:: setting (bool) – True if the tree requires reading across rows

Sets a hint for the theme to draw even/odd rows in the self with different colors, also known as “zebra striping”.

This function tells the GTK+ theme that the user interface for your application requires users to read across tree rows and associate cells with one another.

Do not use it just because you prefer the appearance of the ruled tree; that’s a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

Deprecated since version 3.14.

set_search_column(column)[source]¶

Parameters:: column (int) – the column of the model to search in, or -1 to disable searching

Sets column as the column where the interactive search code should search in for the current model.

If the search column is set, users can use the “start-interactive-search” key binding to bring up search popup. The enable-search property controls whether simply typing text will also start an interactive search.

Note that column refers to a column of the current model. The search column is reset to -1 when the model is changed.

set_search_entry(entry)[source]¶

Parameters:: entry (Gtk.Entry or None) – the entry the interactive search code of self should use or None

Sets the entry which the interactive search code will use for this self. This is useful when you want to provide a search entry in our interface at all time at a fixed position. Passing None for entry will make the interactive search code use the built-in popup entry again.

New in version 2.10.

set_search_equal_func(search_equal_func, *search_user_data)[source]¶

Parameters:

search_equal_func (Gtk.TreeViewSearchEqualFunc) – the compare function to use during the search
search_user_data (object or None) – user data to pass to search_equal_func, or None

Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality Gtk.TreeViewSearchEqualFunc returns False on matches.

set_search_position_func(func, *data)[source]¶

Parameters:

func (Gtk.TreeViewSearchPositionFunc or None) – the function to use to position the search dialog, or None to use the default search position function
data (object or None) – user data to pass to func, or None

Sets the function to use when positioning the search dialog.

New in version 2.10.

set_show_expanders(enabled)[source]¶

Parameters:: enabled (bool) – True to enable expander drawing, False otherwise.

Sets whether to draw and enable expanders and indent child rows in self. When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using Gtk.TreeView.set_level_indentation(). This does not have any visible effects for lists.

New in version 2.12.

set_tooltip_cell(tooltip, path, column, cell)[source]¶

Parameters:

tooltip (Gtk.Tooltip) – a Gtk.Tooltip
path (Gtk.TreePath or None) – a Gtk.TreePath or None
column (Gtk.TreeViewColumn or None) – a Gtk.TreeViewColumn or None
cell (Gtk.CellRenderer or None) – a Gtk.CellRenderer or None

Sets the tip area of tooltip to the area path, column and cell have in common. For example if path is None and column is set, the tip area will be set to the full area covered by column. See also Gtk.Tooltip.set_tip_area().

Note that if path is not specified and cell is set and part of a column containing the expander, the tooltip might not show and hide at the correct position. In such cases path must be set to the current node under the mouse cursor for this function to operate correctly.

See also Gtk.TreeView.set_tooltip_column() for a simpler alternative.

New in version 2.12.

set_tooltip_column(column)[source]¶

Parameters:: column (int) – an integer, which is a valid column number for self’s model

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have Gtk.TreeView handle these automatically for you. column should be set to the column in self’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, Gtk.Widget :has-tooltip will be set to True and self will connect a Gtk.Widget ::query-tooltip signal handler.

Note that the signal handler sets the text with Gtk.Tooltip.set_markup(), so &, <, etc have to be escaped in the text.

New in version 2.12.

set_tooltip_row(tooltip, path)[source]¶

Parameters:

tooltip (Gtk.Tooltip) – a Gtk.Tooltip
path (Gtk.TreePath) – a Gtk.TreePath

Sets the tip area of tooltip to be the area covered by the row at path. See also Gtk.TreeView.set_tooltip_column() for a simpler alternative. See also Gtk.Tooltip.set_tip_area().

New in version 2.12.

set_vadjustment(adjustment)[source]¶

Parameters:: adjustment (Gtk.Adjustment or None) – The Gtk.Adjustment to set, or None

Sets the Gtk.Adjustment for the current vertical aspect.

Deprecated since version 3.0: Use Gtk.Scrollable.set_vadjustment()

unset_rows_drag_dest()[source]¶: Undoes the effect of Gtk.TreeView.enable_model_drag_dest(). Calling this method sets Gtk.TreeView :reorderable to False.

unset_rows_drag_source()[source]¶: Undoes the effect of Gtk.TreeView.enable_model_drag_source(). Calling this method sets Gtk.TreeView :reorderable to False.

Signal Details¶

Gtk.TreeView.signals.columns_changed(tree_view)¶

Signal Name:: columns-changed
Flags:: RUN_LAST
Parameters:: tree_view (Gtk.TreeView) – The object which received the signal

The number of columns of the treeview has changed.

Gtk.TreeView.signals.cursor_changed(tree_view)¶

Signal Name:: cursor-changed
Flags:: RUN_LAST
Parameters:: tree_view (Gtk.TreeView) – The object which received the signal

The position of the cursor (focused cell) has changed.

Gtk.TreeView.signals.expand_collapse_cursor_row(tree_view, object, p0, p1)¶

Signal Name:

expand-collapse-cursor-row

Flags:

Parameters:

tree_view (Gtk.TreeView) – The object which received the signal
object (bool) –
p0 (bool) –
p1 (bool) –

Return type:

Gtk.TreeView.signals.move_cursor(tree_view, step, direction)¶

Signal Name:

move-cursor

Flags:

Parameters:

tree_view (Gtk.TreeView) – The object which received the signal
step (Gtk.MovementStep) – the granularity of the move, as a Gtk.MovementStep. Gtk.MovementStep.LOGICAL_POSITIONS, Gtk.MovementStep.VISUAL_POSITIONS, Gtk.MovementStep.DISPLAY_LINES, Gtk.MovementStep.PAGES and Gtk.MovementStep.BUFFER_ENDS are supported. Gtk.MovementStep.LOGICAL_POSITIONS and Gtk.MovementStep.VISUAL_POSITIONS are treated identically.
direction (int) – the direction to move: +1 to move forwards; -1 to move backwards. The resulting movement is undefined for all other values.

Returns:

True if step is supported, False otherwise.

Return type:

The Gtk.TreeView ::move-cursor signal is a keybinding signal which gets emitted when the user presses one of the cursor keys.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically. In contrast to Gtk.TreeView.set_cursor() and Gtk.TreeView.set_cursor_on_cell() when moving horizontally Gtk.TreeView ::move-cursor does not reset the current selection.

Parameters:

tree_view (Gtk.TreeView) – The object which received the signal
path (Gtk.TreePath) – the Gtk.TreePath for the activated row
column (Gtk.TreeViewColumn) – the Gtk.TreeViewColumn in which the activation occurred

The “row-activated” signal is emitted when the method Gtk.TreeView.row_activated() is called, when the user double clicks a treeview row with the “activate-on-single-click” property set to False, or when the user single clicks a row when the “activate-on-single-click” property set to True. It is also emitted when a non-editable row is selected and one of the keys: Space, Shift+Space, Return or Enter is pressed.

For selection handling refer to the tree widget conceptual overview as well as Gtk.TreeSelection.
