.SH NAME
|
|
XtQueryGeometry \- query the preferred geometry of a child widget
|
|
.SH SYNTAX
|
|
XtGeometryResult XtQueryGeometry(\fIw\fP, \fIintended\fP, \
|
|
\fIpreferred_return\fP)
|
|
.br
|
|
Widget \fIw\fP\^;
|
|
.br
|
|
XtWidgetGeometry *\fIintended\fP, *\fIpreferred_return\fP\^;
|
|
.SH ARGUMENTS
|
|
.IP \fIintended\fP 1i
|
|
Specifies any changes the parent plans to make to the child's geometry or
|
|
NULL.
|
|
.IP \fIpreferred_return\fP 1i
|
|
Returns the child widget's preferred geometry.
|
|
.IP \fIw\fP 1i
|
|
Specifies the widget.
|
|
.SH DESCRIPTION
|
|
To discover a child's preferred geometry,
|
|
the child's parent sets any changes
|
|
that it intends to make to the child's geometry in the corresponding fields of
|
|
the intended structure, sets the corresponding bits in intended.request_mode,
|
|
and calls
|
|
.ZN XtQueryGeometry .
|
|
.LP
|
|
.ZN XtQueryGeometry
|
|
clears all bits in the preferred_return->request_mode and checks the
|
|
query_geometry field of the specified widget's class record.
|
|
If query_geometry is not NULL,
|
|
.ZN XtQueryGeometry
|
|
calls the query_geometry procedure and passes as arguments the
|
|
specified widget, intended, and preferred_return structures.
|
|
If the intended argument is NULL,
|
|
.ZN XtQueryGeometry
|
|
replaces it with a pointer to an
|
|
.ZN XtWidgetGeometry
|
|
structure with request_mode=0 before calling query_geometry.
