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 widget as the new
reference and repeats the search after deleting the first component from
the specified names. If it cannot 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 contain more than
one widget name (separated by periods) for widgets that are not direct
children of the specified reference 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 component, 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 window and display pointer into the appropriate widget instance.
