<!-- ##### ENUM GtkWidgetFlags ##### -->
<para>
-
+Tells about certain properties of the widget.
</para>
@GTK_TOPLEVEL:
+ 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.
@GTK_NO_WINDOW:
+ Indicative for a widget that does not provide its own #GdkWindow.
+ Visible action (e.g. drawing) is performed on the parent's #GdkWindow.
@GTK_REALIZED:
+ Set by gtk_widget_realize(), unset by gtk_widget_unrealize().
+ A realized widget has an associated #GdkWindow.
@GTK_MAPPED:
+ 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).
@GTK_VISIBLE:
+ Set by gtk_widget_show(), unset by gtk_widget_hide(). Implies that a
+ widget will be mapped as soon as its parent is mapped.
@GTK_SENSITIVE:
+ 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 widgets sensitivity is to have this flag set.
@GTK_PARENT_SENSITIVE:
+ Set and unset by gtk_widget_set_sensitive() operations on the
+ parents of the widget.
+ This is the second premise for the widgets 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.
@GTK_CAN_FOCUS:
+ Determines whether a widget is able to handle focus grabs.
@GTK_HAS_FOCUS:
+ 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.
@GTK_CAN_DEFAULT:
+ The widget is allowed to receive the default action via
+ gtk_widget_grab_default().
@GTK_HAS_DEFAULT:
+ The widget currently is receiving the default action.
@GTK_HAS_GRAB:
+ 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.
@GTK_RC_STYLE:
+ Indicates that the widgets 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.
@GTK_COMPOSITE_CHILD:
+ Indicates that the widget is a composite child of its parent; see
+ gtk_widget_push_composite_child(), gtk_widget_pop_composite_child().
@GTK_NO_REPARENT:
@GTK_APP_PAINTABLE:
+ Set and unset by gtk_widget_set_app_paintable().
@GTK_RECEIVES_DEFAULT:
+ 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.
@GTK_DOUBLE_BUFFERED:
+ Set and unset by gtk_widget_set_double_buffered().
+ Indicates that exposes done on the widget should be double-buffered.
