XtSetWMColormapWindows(3Xt) XT FUNCTIONS XtSetWMColormapWindows(3Xt)NAME
XtSetWMColormapWindows - Set the value of the WM_COLORMAP_WINDOWS property
SYNTAX
void XtSetWMColormapWindows(widget, list, count)
Widget widget;
Widget* list;
Cardinal count;
ARGUMENTS
widget Specifies the widget on whose window the WM_COLORMAP_WINDOWS property will be stored. Must be of class Core or any subclass
thereof.
list Specifies a list of widgets whose windoware are potentially to be listed in the WM_COLORMAP_WINDOWS property.
count Specifies the number of widgets in list.
DESCRIPTION
XtSetWMColormapWindows returns immediately if widget is not realized or if count is zero. Otherwise, XtSetWMColormapWindows constructs an
ordered list of windows by examining each widget in list in turn and ignoring the widget if it is not realized, or adding the widget's win-
dow to the window list if the widget is realized and its colormap resource is different from the colormap resources of all widgets whose
windows are already on the window list.
Finally, XtSetWMColormapWindows stores the resulting window list in the WM_COLORMAP_WINDOWS property on the specified widget's window.

XtRealizeWidget(3Xt) XT FUNCTIONS XtRealizeWidget(3Xt)NAME
XtRealizeWidget, XtIsRealized, XtUnrealizeWidget - realize and unrealize widgets
SYNTAX
void XtRealizeWidget(w)
Widget w;
Boolean XtIsRealized(w)
Widget w;
void XtUnrealizeWidget(w)
Widget w;
ARGUMENTS
w Specifies the widget.
DESCRIPTION
If the widget is already realized, XtRealizeWidget simply returns. Otherwise, it performs the following:
o Binds all action names in the widget's translation table to procedures (see Section 10.1.2).
o Makes a post-order traversal of the widget tree rooted at the specified widget and calls the change_managed procedure of each compos-
ite widget that has one or more managed children.
o Constructs an XSetWindowAttributes structure filled in with information derived from the Core widget fields and calls the realize pro-
cedure for the widget, which adds any widget-specific attributes and creates the X window.
o If the widget is not a subclass of compositeWidgetClass, XtRealizeWidget returns; otherwise, it continues and performs the following:
- Descends recursively to each of the widget's managed children and calls the realize procedures. Primitive widgets that instanti-
ate children are responsible for realizing those children themselves.
- Maps all of the managed children windows that have mapped_when_managed True. (If a widget is managed but mapped_when_managed is
False, the widget is allocated visual space but is not displayed. Some people seem to like this to indicate certain states.)
If the widget is a top-level shell widget (that is, it has no parent), and mapped_when_managed is True, XtRealizeWidget maps the widget
window.
The XtIsRealized function returns True if the widget has been realized, that is, if the widget has a nonzero X window ID.
Some widget procedures (for example, set_values) might wish to operate differently after the widget has been realized.
The XtUnrealizeWidget function destroys the windows of an existing widget and all of its children (recursively down the widget tree). To
recreate the windows at a later time, call XtRealizeWidget again. If the widget was managed, it will be unmanaged automatically before its
window is freed.
