|
|
.IP \fIdisplay\fP 1i
|
|
Specifies the display\*(Di.
|
|
.IP \fInames\fP 1i
|
|
Specifies the fully qualified name of the desired widget.
|
|
.IP \fIreference\fP 1i

Specifies the widget from which the search is to start.
|
|
.IP \fIwindow\fP 1i
|
|

|
|
.SH DESCRIPTION
|
|
The
|
|
.ZN 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
|
|
.ZN 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,
|
|
.ZN XtNameToWidget
|
|
returns NULL.
|
|
.LP
|
|
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.
|
|
.LP
|
|
If more than one child of the reference widget matches the name,
|
|
.ZN XtNameToWidget
|
|
can return any of the children.
|
|
The \*(xI 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,
|
|
.ZN XtNameToWidget
|
|
can return NULL if the single branch that it follows does not
|
|
contain the named widget.
|
|
That is,
|
|
.ZN XtNameToWidget
|
|
does not back up and follow other matching branches of the widget tree.
|
|
.LP
|
|
The
|
|
.ZN XtWindowToWidget
|
|
function translates the specified window and display pointer into the
|
|
appropriate widget instance.
