AboutDialogSignalName

Emitted when the user activates the default widget of window.

This is a keybinding signal.

Emitted when the user activates the currently focused widget of window.

This is a keybinding signal.

Emitted every time a URL is activated.

Applications may connect to it to override the default behaviour, which is to call [funcGtk.show_uri].

Emitted when the user clicks on the close button of the window.

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.

Emitted when the text direction of a widget changes.

Emitted when the user enables or disables interactive debugging.

When toggle is true, interactive debugging is toggled on or off, when it is false, the debugger will be pointed at the widget under the pointer.

This is a keybinding signal.

The default bindings for this signal are Ctrl-Shift-I and Ctrl-Shift-D.

Emitted when widget is hidden.

Emitted if keyboard navigation fails.

See [methodGtk.Widget.keynav_failed] for details.

emitted when the set of accelerators or mnemonics that are associated with window changes.

Emitted when widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with [propertyGtk.Widget: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 [signalGtk.Widget::unmap].

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.

Emitted when the focus is moved.

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

(C Language Example):

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use canonical parameter names as detail strings for the notify signal.

Emitted when the widgets tooltip is about to be shown.

This happens when the [propertyGtk.Widget: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.

Emitted when widget is associated with a GdkSurface.

This means that [methodGtk.Widget.realize] has been called or the widget has been mapped (that is, it is going to be drawn).

Emitted when widget is shown.

Emitted when the widget state changes.

See [methodGtk.Widget.get_state_flags].

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.

Emitted when the GdkSurface associated with widget is destroyed.

This means that [methodGtk.Widget.unrealize] has been called or the widget has been unmapped (that is, it is going to be hidden).

The GtkApplication associated with the window.

The application will be kept alive for at least as long as it has any windows associated with it (see g_application_hold() for a way to keep it alive without windows).

Normally, the connection between the application and the window will remain until the window is destroyed, but you can explicitly remove it by setting the :application property to nil.

This property is only relevant for widgets that can take focus.

Whether ‘focus rectangles’ are currently visible in this window.

This property is maintained by GTK based on user input and should not be set by applications.

The focus widget.

Whether this widget itself will accept the input focus.

Whether the window is fullscreen.

Setting this property is the equivalent of calling [methodGtk.Window.fullscreen] or [methodGtk.Window.unfullscreen]; either operation is asynchronous, which means you will need to connect to the notify signal in order to know whether the operation was successful.

How to distribute horizontal space if widget gets extra space.

Whether the window frame should handle F10 for activating menubars.

Whether the widget is the default widget.

Whether the widget has the input focus.

Enables or disables the emission of the query-tooltip signal on widget.

A value of true indicates that widget can have a tooltip, in this case the widget will be queried using [signalGtk.Widget::query-tooltip] to determine whether it will provide a tooltip or not.

The license of the program, as free-form text.

This string is displayed in a text view in a secondary dialog, therefore it is fine to use a long multi-paragraph text. Note that the text is only wrapped in the text view if the “wrap-license” property is set to TRUE; otherwise the text itself must contain the intended linebreaks.

When setting this property to a non-NULL value, the [propertyGtk.AboutDialog:license-type] property is set to GTK_LICENSE_CUSTOM as a side effect.

The text may contain links in this format <http://www.some.place/> and email references in the form <mail-tosome.body>, and these will be converted into clickable links.

The license of the program.

The GtkAboutDialog will automatically fill out a standard disclaimer and link the user to the appropriate online resource for the license text.

If GTK_LICENSE_UNKNOWN is used, the link used will be the same specified in the [propertyGtk.AboutDialog:website] property.

If GTK_LICENSE_CUSTOM is used, the current contents of the [propertyGtk.AboutDialog:license] property are used.

For any other [enumGtk.License] value, the contents of the [propertyGtk.AboutDialog:license] property are also set by this property as a side effect.

A logo for the about box.

If it is NULL, the default window icon set with [idgtk_window_set_default_icon_name] will be used.

A named icon to use as the logo for the about box.

This property overrides the [propertyGtk.AboutDialog:logo] property.

Margin on bottom side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from [methodGtk.Widget.set_size_request] for example.

Margin on end of widget, horizontally.

This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from [methodGtk.Widget.set_size_request] for example.

Margin on start of widget, horizontally.

This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from [methodGtk.Widget.set_size_request] for example.

Margin on top side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from [methodGtk.Widget.set_size_request] for example.

Whether the window is maximized.

Setting this property is the equivalent of calling [methodGtk.Window.maximize] or [methodGtk.Window.unmaximize]; either operation is asynchronous, which means you will need to connect to the notify signal in order to know whether the operation was successful.

Whether mnemonics are currently visible in this window.

This property is maintained by GTK based on user input, and should not be set by applications.

If true, the window is modal.

The name of the widget.

The requested opacity of the widget.

How content outside the widget’s content area is treated.

This property is meant to be set by widget implementations, typically in their instance init function.

Information about the system on which the program is running.

This information is displayed in a separate page, therefore it is fine to use a long multi-paragraph text. Note that the text should contain the intended linebreaks.

The text may contain links in this format <http://www.some.place/> and email references in the form <mail-tosome.body>, and these will be converted into clickable links.

The title of the window.

Sets the text of tooltip to be the given string, which is marked up with Pango markup.

Also see [methodGtk.Tooltip.set_markup].

This is a convenience property which will take care of getting the tooltip shown if the given string is not nil: [propertyGtk.Widget:has-tooltip] will automatically be set to true and there will be taken care of [signalGtk.Widget::query-tooltip] in the default signal handler.

Note that if both [propertyGtk.Widget:tooltip-text] and [propertyGtk.Widget:tooltip-markup] are set, the last one wins.
