§Signals

§desktop-folder

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show the user’s Desktop folder in the file list.

The default binding for this signal is Alt-D.

Action

§down-folder

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser go to a child of the current folder in the file hierarchy. The subfolder that will be used is displayed in the path bar widget of the file chooser. For example, if the path bar is showing “/foo/bar/baz”, with bar currently displayed, then this will cause the file chooser to switch to the “baz” subfolder.

The default binding for this signal is Alt-Down.

Action

§home-folder

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show the user’s home folder in the file list.

The default binding for this signal is Alt-Home.

Action

§location-popup

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show a “Location” prompt which the user can use to manually type the name of the file he wishes to select.

The default bindings for this signal are Control-L with a @path string of “” (the empty string). It is also bound to / with a @path string of “/” (a slash): this lets you type / and immediately type a path name. On Unix systems, this is bound to (tilde) with a @path string of “” itself for access to home directories.

Action

§location-popup-on-paste

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show a “Location” prompt when the user pastes into a FileChooserWidget.

The default binding for this signal is Control-V.

Action

§location-toggle-popup

Emitted when the user asks for it.

This is a keybinding signal.

This is used to toggle the visibility of a “Location” prompt which the user can use to manually type the name of the file he wishes to select.

The default binding for this signal is Control-L.

Action

§places-shortcut

Emitted when the user asks for it.

This is a keybinding signal.

This is used to move the focus to the places sidebar.

The default binding for this signal is Alt-P.

Action

§quick-bookmark

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser switch to the bookmark specified in the @bookmark_index parameter. For example, if you have three bookmarks, you can pass 0, 1, 2 to this signal to switch to each of them, respectively.

The default binding for this signal is Alt-1, Alt-2, etc. until Alt-0. Note that in the default binding, that Alt-1 is actually defined to switch to the bookmark at index 0, and so on successively.

Action

§recent-shortcut

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show the Recent location.

The default binding for this signal is Alt-R.

Action

§search-shortcut

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser show the search entry.

The default binding for this signal is Alt-S.

Action

§show-hidden

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser display hidden files.

The default binding for this signal is Control-H.

Action

§up-folder

Emitted when the user asks for it.

This is a keybinding signal.

This is used to make the file chooser go to the parent of the current folder in the file hierarchy.

The default binding for this signal is Alt-Up.

Action

Widget
§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering above @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

fn dynamic_cast<T>(self) -> Result<T, Self>
where T: ObjectType,

Tries to cast to an object of type T. This handles upcasting, downcasting and casting between interface and interface implementors. All checks are performed at runtime, while upcast will do many checks at compile-time already. downcast will perform the same checks at runtime as dynamic_cast, but will also ensure some amount of compile-time safety.
