Libxfce4ui.dialog_confirm_close_tabs(parent, num_tabs, show_confirm_box, confirm_box_checked)
Parameters:

  • parent (Gtk.Window or None) – transient parent of the dialog, or None.

  • num_tabs (int) – the number of open tabs for display to user

  • show_confirm_box (bool) – whether to ask the user if this confirmation shall be shown in the future

  • confirm_box_checked (bool or None) – state of confirmation checkbox

Returns:

Gtk.ResponseType.CANCEL if cancelled, Gtk.ResponseType.YES if the user wants to close the window, Gtk.ResponseType.CLOSE if the user wants to close the tab, and Gtk.ResponseType.NONE for an error.

Return type:

int

Runs a dialog to ask the user whether they want to close the whole window, close the current tab, or cancel.

If num_tabs is non-negative, the message to the user will state that there are num_tabs open tabs. If num_tabs is negative, then the message to the user will state simply that there are “multiple open tabs”.

If show_confirm_box is True a checkbox is added to the dialog to allow the user to set whether they wish to see this dialog in future. The initial state of the checkbox is determined by the value stored at confirm_box_checked and the value at confirm_box_checked after returning records the state of the checkbox. If show_confirm_box is False, confirm_box_checked is ignored and may be None.

Libxfce4ui.gtk_menu_popup_until_mapped(menu, parent_menu_shell, parent_menu_item, func, data, button, activate_time)
Parameters:

  • menu (Gtk.Menu) – a Gtk.Menu.

  • parent_menu_shell (Gtk.Widget or None) – the menu shell containing the triggering menu item, or None.

  • parent_menu_item (Gtk.Widget or None) – the menu item whose activation triggered the popup, or None.

  • func (Gtk.MenuPositionFunc or None) – a user supplied function used to position the menu, or None.

  • data (object or None) – user supplied data to be passed to func.

  • button (int) – the mouse button which was pressed to initiate the event.

  • activate_time (int) – the time at which the activation event occurred.

Returns:

True if the menu could be mapped, False otherwise.

Return type:

bool

Attempts to pop up a Gtk.Menu for a short duration. Unlike the original Gtk.Menu.popup(), this function will verify that the menu has been mapped or will keep trying for up to 250ms. It will also return a value indicating whether the menu was eventually mapped or not. Following is an excerpt from the GTK+ Documentation on Gtk.Menu.

Displays a menu and makes it available for selection.

Applications can use this function to display context-sensitive menus, and will typically supply None for the parent_menu_shell, parent_menu_item, func and data parameters. The default menu positioning function will position the menu at the current mouse cursor position.

The button parameter should be the mouse button pressed to initiate the menu popup. If the menu popup was initiated by something other than a mouse button press, such as a mouse button release or a keypress, button should be 0.

The activate_time parameter is used to conflict-resolve initiation of concurrent requests for mouse/keyboard grab requests. To function properly, this needs to be the timestamp of the user event (such as a mouse click or key press) that caused the initiation of the popup. Only if no such event is available, Gtk.get_current_event_time() can be used instead.

New in version 4.14.

Parameters:
Raises:

GLib.Error

Returns:

Returns:

True on success, False if error is set.

Return type:

bool
