NAME

XtIsRealized − determine whether a widget has been realized. 

SYNOPSIS

Boolean XtIsRealized(object)
    Widget object;

Inputs

objectSpecifies the object whose state is to be tested; may be of class Object or any subclass thereof. 

Returns

True if object is realized; False otherwise. 

DESCRIPTION

XtIsRealized() returns True if the specified object (or its nearest widget ancestor) has been realized, and False otherwise.  A widget is realized if it has a nonzero X window ID. 

USAGE

XtIsRealized() is implemented as a function when called from application code, but is replaced by a more efficient macro when called from widget code that includes the file <X11/IntrinsicP.h>. 

Some widget methods (for example, set_values()) might wish to operate differently depending on whether the widget has been realized.  In particular, no Xlib calls can refer to a widget’s window until the widget is realized.
