XtNameToWidget(3Xt) XT FUNCTIONS XtNameToWidget(3Xt)
XtNameToWidget, XtWindowToWidget - translating strings to
widgets or widgets to windows
Widget XtNameToWidget(Widget reference, String names);
Widget XtWindowToWidget(Display *display, Window window);
display Specifies the display on which the window is
defined.
names Specifies the fully qualified name of the desired
widget.
reference Specifies the widget from which the search is to
start.
window Specify the window for which you want the widget.
The XtNameToWidget function looks for a widget whose name is
the first component in the specified names and that is a
pop-up child of reference (or a normal child if reference is
a subclass of compositeWidgetClass). It then uses that wid-
get as the new reference and repeats the search after delet-
ing the first component from the specified names. If it can-
not find the specified widget, XtNameToWidget returns NULL.
Note that the names argument contains the name of a widget
with respect to the specified reference widget and can con-
tain more than one widget name (separated by periods) for
widgets that are not direct children of the specified refer-
ence widget.
If more than one child of the reference widget matches the
name, XtNameToWidget can return any of the children. The
Intrinsics do not require that all children of a widget have
unique names. If the specified names contain more than one
component and if more than one child matches the first com-
ponent, XtNameToWidget can return NULL if the single branch
that it follows does not contain the named widget. That is,
XtNameToWidget does not back up and follow other matching
branches of the widget tree.
The XtWindowToWidget function translates the specified win-
dow and display pointer into the appropriate widget
instance.
