Set and unset by gtk_widget_set_app_paintable().
Must be set on widgets whose window the application directly draws on,
in order to keep GTK+ from overwriting the drawn stuff. See
The widget is allowed to receive the default action via gtk_widget_grab_default() and will reserve space to draw the default if possible
Determines whether a widget is able to handle focus grabs.
Indicates that the widget is a composite child of its parent; see gtk_widget_push_composite_child(), gtk_widget_pop_composite_child().
Set and unset by gtk_widget_set_double_buffered().
Indicates that exposes done on the widget should be
double-buffered. See
The widget currently is receiving the default action and should be drawn appropriately if possible
Set by gtk_widget_grab_focus() for widgets that also have %GTK_CAN_FOCUS set. The flag will be unset once another widget grabs the focus.
Set by gtk_grab_add(), unset by gtk_grab_remove(). It means that the widget is in the grab_widgets stack, and will be the preferred one for receiving events other than ones of cosmetic value.
Set by gtk_widget_map(), unset by gtk_widget_unmap(). Only realized widgets can be mapped. It means that gdk_window_show() has been called on the widgets window(s).
Unused since before GTK+ 1.2, will be removed in a future version.
Indicative for a widget that does not provide its own #GdkWindow. Visible action (e.g. drawing) is performed on the parent's #GdkWindow.
Set and unset by gtk_widget_set_sensitive() operations on the parents of the widget. This is the second premise for the widget's sensitivity. Once it has %GTK_SENSITIVE and %GTK_PARENT_SENSITIVE set, its state is effectively sensitive. This is expressed (and can be examined) by the #GTK_WIDGET_IS_SENSITIVE macro.
Indicates that the widget's style has been looked up through the rc mechanism. It does not imply that the widget actually had a style defined through the rc mechanism.
Set by gtk_widget_realize(), unset by gtk_widget_unrealize(). A realized widget has an associated #GdkWindow.
The widget when focused will receive the default action and have %GTK_HAS_DEFAULT set even if there is a different widget set as default.
Set and unset by gtk_widget_set_sensitive(). The sensitivity of a widget determines whether it will receive certain events (e.g. button or key presses). One premise for the widget's sensitivity is to have this flag set.
widgets without a real parent, as there are #GtkWindows and #GtkMenus have this flag set throughout their lifetime. Toplevel widgets always contain their own #GdkWindow.
Set by gtk_widget_show(), unset by gtk_widget_hide(). Implies that a widget will be mapped as soon as its parent is mapped.
Tells about certain properties of the widget.
