PopupSignalName

Emitted when surface starts being present on the monitor.

Emitted when GDK receives an input event for surface.

Emitted when the size of surface is changed, or when relayout should be performed.

Surface size is reported in ”application pixels”, not ”device pixels” (see gdk_surface_get_scale_factor()).

Emitted when surface stops being present on the monitor.

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 part of the surface needs to be redrawn.

Whether to hide on outside clicks.

The mouse pointer for the GdkSurface.

The GdkDisplay connection of the surface.

The GdkFrameClock of the surface.

The height of the surface, in pixels.

Whether the surface is mapped.

The parent surface.

The scale factor of the surface.

The width of the surface in pixels.
