Class Details¶

class Gtk.TreeSelection(**kwargs)¶

Bases:: GObject.Object
Abstract:: No
Structure:: Gtk.TreeSelectionClass

The Gtk.TreeSelection object is a helper object to manage the selection for a Gtk.TreeView widget. The Gtk.TreeSelection object is automatically created when a new Gtk.TreeView widget is created, and cannot exist independently of this widget. The primary reason the Gtk.TreeSelection objects exists is for cleanliness of code and API. That is, there is no conceptual reason all these functions could not be methods on the Gtk.TreeView widget instead of a separate function.

The Gtk.TreeSelection object is gotten from a Gtk.TreeView by calling Gtk.TreeView.get_selection(). It can be manipulated to check the selection status of the tree, as well as select and deselect individual rows. Selection is done completely view side. As a result, multiple views of the same model can have completely different selections. Additionally, you cannot change the selection of a row on the model that is not currently displayed by the view without expanding its parents first.

One of the important things to remember when monitoring the selection of a view is that the Gtk.TreeSelection ::changed signal is mostly a hint. That is, it may only emit one signal when a range of rows is selected. Additionally, it may on occasion emit a Gtk.TreeSelection ::changed signal when nothing has happened (mostly as a result of programmers calling select_row on an already selected row).

count_selected_rows()[source]¶

Returns:: The number of rows selected.
Return type:: int

Returns the number of rows that have been selected in tree.

New in version 2.2.

get_mode()[source]¶

Returns:: the current selection mode
Return type:: Gtk.SelectionMode

Gets the selection mode for self. See Gtk.TreeSelection.set_mode().

get_selected()[source]¶

Returns:

model:: the Gtk.TreeModel
iter:: The Gtk.TreeIter or None

Return type:

(model: Gtk.TreeModel, iter: Gtk.TreeIter or None)

Sets iter to the currently selected node, if self is set to Gtk.SelectionMode.SINGLE or Gtk.SelectionMode.BROWSE.

The iter argument may be None if you just want to test if self has any selected nodes.

The model argument is filled with the current model as a convenience.

This function will not work with Gtk.SelectionMode.MULTIPLE. See Gtk.TreeSelection.get_selected_rows() instead.

get_selected_rows()[source]¶

Returns:: A list containing a Gtk.TreePath for each selected row and a Gtk.TreeModel or None.
Return type:: (Gtk.TreeModel, [Gtk.TreePath])

Creates a list of path of all selected rows.

Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of Gtk.TreeRowReferences.

To do this, you can use Gtk.TreeRowReference.new().

To free the return value, use:

g_list_free_full (list, (GDestroyNotify) gtk_tree_path_free);

New in version 2.2.

get_tree_view()[source]¶

Returns:: A Gtk.TreeView
Return type:: Gtk.TreeView

Returns the tree view associated with self.

iter_is_selected(iter)[source]¶

Parameters:: iter (Gtk.TreeIter) – A valid Gtk.TreeIter
Returns:: True, if iter is selected
Return type:: bool

Returns True if the row at iter is currently selected.

path_is_selected(path)[source]¶

Parameters:: path (Gtk.TreePath) – A Gtk.TreePath to check selection on.
Returns:: True if path is selected.
Return type:: bool

Returns True if the row pointed to by path is currently selected. If path does not point to a valid location, False is returned

select_all()[source]¶: Selects all the nodes. self must be set to Gtk.SelectionMode.MULTIPLE mode.

select_iter(iter)[source]¶

Parameters:: iter (Gtk.TreeIter) – The Gtk.TreeIter to be selected.

Selects the specified iterator.

select_path(path)[source]¶

Parameters:: path (Gtk.TreePath) – The Gtk.TreePath to be selected.

Select the row at path.

select_range(start_path, end_path)[source]¶

Parameters:

start_path (Gtk.TreePath) – The initial node of the range.
end_path (Gtk.TreePath) – The final node of the range.

Selects a range of nodes, determined by start_path and end_path inclusive. self must be set to Gtk.SelectionMode.MULTIPLE mode.

selected_foreach(func, *data)[source]¶

Parameters:

func (Gtk.TreeSelectionForeachFunc) – The function to call for each selected node.
data (object or None) – user data to pass to the function.

Calls a function for each selected node. Note that you cannot modify the tree or selection from within this function. As a result, Gtk.TreeSelection.get_selected_rows() might be more useful.

set_mode(type)[source]¶

Parameters:: type (Gtk.SelectionMode) – The selection mode

Sets the selection mode of the self. If the previous type was Gtk.SelectionMode.MULTIPLE, then the anchor is kept selected, if it was previously selected.

set_select_function(func, *data)[source]¶

Parameters:

func (Gtk.TreeSelectionFunc or None) – The selection function. May be None
data (object or None) – The selection function’s data. May be None

Sets the selection function.

If set, this function is called before any node is selected or unselected, giving some control over which nodes are selected. The select function should return True if the state of the node may be toggled, and False if the state of the node should be left unchanged.

unselect_all()[source]¶: Unselects all the nodes.

unselect_iter(iter)[source]¶

Parameters:: iter (Gtk.TreeIter) – The Gtk.TreeIter to be unselected.

Unselects the specified iterator.

unselect_path(path)[source]¶

Parameters:: path (Gtk.TreePath) – The Gtk.TreePath to be unselected.

Unselects the row at path.

unselect_range(start_path, end_path)[source]¶

Parameters:

start_path (Gtk.TreePath) – The initial node of the range.
end_path (Gtk.TreePath) – The initial node of the range.

Unselects a range of nodes, determined by start_path and end_path inclusive.

New in version 2.2.

do_changed() virtual¶: Signal emitted whenever the selection has (possibly) changed.

Signal Details¶

Gtk.TreeSelection.signals.changed(tree_selection)¶

Signal Name:: changed
Flags:: RUN_FIRST
Parameters:: tree_selection (Gtk.TreeSelection) – The object which received the signal

Emitted whenever the selection has (possibly) changed. Please note that this signal is mostly a hint. It may only be emitted once when a range of rows are selected, and it may occasionally be emitted when nothing has happened.

Property Details¶

Gtk.TreeSelection.props.mode¶

Name:: mode
Type:: Gtk.SelectionMode
Default Value:: Gtk.SelectionMode.SINGLE
Flags:: READABLE, WRITABLE, EXPLICIT_NOTIFY

Selection mode. See Gtk.TreeSelection.set_mode() for more information on this property.

New in version 3.2.
