Detailed Description

A GtkWidget C++ wrapper interface.

Provides Widget, the base class for widgets that make up the GTK+ graphical user interface, such as windows, menus, buttons, scrollbars editors, drawing areas, and so on.

Enumeration Type Documentation

enum WidgetFlags

WidgetFlags tells about certain properties of the widget.

Enumeration values:

TOP_LEVEL Widgets without a real parent, such as Windows and Menus have this flag set throughout their lifetime; Toplevel widgets always contain their own Gdk::Window.

NO_WINDOW Indicative for a widget that does not provide its own Gdk::Window; For such widgets, visible actions (such as drawing) are performed on the parent's Gdk::Window.

REALIZED Set by realize(), unset by unrealize(); A realized widget has an associated Gdk::Window.

MAPPED Set by map(), unset by unmap(); Only realized widgets can be mapped; It means that show() has been called on the widgets window(s).

VISIBLE Set by show(), unset by hide(); Implies that a widget will be mapped as soon as its parent is mapped.

SENSITIVE Set and unset by set_sensitive(); The sensitivity of a widget determines whether it will receive certain events (such as button or key presses); One premise for the widget's sensitivity is to have this flag set.

PARENT_SENSITIVE Set and unset by set_sensitive() operations on the parents of the widget; This is the second premise for the widget's sensitivity; Once it has SENSITIVE and PARENT_SENSITIVE set, its state is effectively sensitive and Gtk::Widget::is_sensitive() will return true.

CAN_FOCUS Determines whether a widget is able to handle focus grabs.

HAS_FOCUS Set by grab_focus() for widgets that also have CAN_FOCUS set; This flag will be unset once another widget grabs the focus.

CAN_DEFAULT The widget is allowed to receive the default action via grab_default().

HAS_DEFAULT The widget currently is receiving the default action.

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.

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.

COMPOSITE_CHILD Indicates that the widget is a composite child of its parent; see push_composite_child(), pop_composite_child().

NO_REPARENT Unused since before GTK+ 1.2, will be removed in a future version.

APP_PAINTABLE Set and unset by 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.

RECEIVES_DEFAULT The widget when focused will receive the default action and have HAS_DEFAULT set even if there is a different widget set as default.

DOUBLE_BUFFERED Set and unset by set_double_buffered(); Indicates that exposes done on the widget should be double-buffered.

NO_SHOW_ALL The "no_show_all" property, which determines whether calls to show_all() and hide_all() will affect this widget (see Gtk::Widget::set_no_show_all()).

enum WidgetHelpType

WidgetHelpType defines the type of help, either tooltip or "What's this".

Enumeration values:

WIDGET_HELP_TOOLTIP Tooltip help.

WIDGET_HELP_WHATS_THIS "What's this" help.
