/**
|
|
* GtkWidgetFlags:
|
|
* @GTK_TOPLEVEL: widgets without a real parent, as there are #GtkWindow<!-- -->s and
|
|
* #GtkMenu<!-- -->s 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 widget's 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 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.
|
|
* @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() and will reserve space to draw the default if possible
|
|
* @GTK_HAS_DEFAULT: The widget currently is receiving the default action and
|
|
* should be drawn appropriately if possible
|
|
* @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 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.
|
|
* @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: Unused since before GTK+ 1.2, will be removed in a future version.
|
|
* @GTK_APP_PAINTABLE: 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
|
|
* <xref linkend="app-paintable-widgets"/> for a detailed
|
|
* description of this flag.
|
|
* @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. See <xref linkend="double-buffering"/> for a
|
|
* detailed discussion of how double-buffering works in GTK+ and
|
|
* why you may want to disable it for special cases.
|
|
* @GTK_NO_SHOW_ALL:
|
|
*
|
|
* Tells about certain properties of the widget.
