+.SH ARGUMENTS
+.IP \fIreply_return\fP 1i
+Returns the allowed widget size or may be NULL
+if the requesting widget is not interested in handling
+.BR XtGeometryAlmost .
+.IP \fIrequest\fP 1i
+Specifies the desired widget geometry (size, position, border width,
+and stacking order).
+.IP \fIw\fP 1i
+Specifies the widget that is making the request.
+.IP \fIwidth_return\fP 1i
+.br
+.ns
+.IP \fIheight_return\fP 1i
+Return the allowed widget width and height.
+.SH DESCRIPTION
+Depending on the condition,
+.B XtMakeGeometryRequest
+performs the following:
+.IP \(bu 5
+If the widget is unmanaged or the widget's parent is not realized,
+it makes the changes and returns
+.BR XtGeometryYes .
+.IP \(bu 5
+If the parent is not a subclass of
+.B compositeWidgetClass
+or the parent's geometry_manager is NULL,
+it issues an error.
+.IP \(bu 5
+If the widget's being_destroyed field is
+.BR True ,
+it returns
+.BR XtGeometryNo .
+.IP \(bu 5
+If the widget x, y, width, height and border_width fields are
+all equal to the requested values,
+it returns
+.BR XtGeometryYes ;
+otherwise, it calls the parent's geometry_manager procedure
+with the given parameters.
+.IP \(bu 5
+If the parent's geometry manager returns
+.B XtGeometryYes
+and if
+.B XtCWQueryOnly
+is not set in the request_mode
+and if the widget is realized,
+.B XtMakeGeometryRequest
+calls the
+.B XConfigureWindow
+Xlib function to reconfigure the widget's window (set its size, location,
+and stacking order as appropriate).
+.IP \(bu 5
+If the geometry manager returns
+.BR XtGeometryDone ,
+the change has been approved and actually has been done.
+In this case,
+.B XtMakeGeometryRequest
+does no configuring and returns
+.BR XtGeometryYes .
+.B XtMakeGeometryRequest
+never returns
+.BR XtGeometryDone .
+.LP
+Otherwise,
+.B XtMakeGeometryRequest
+returns the resulting value from the parent's geometry manager.
+.LP
+Children of primitive widgets are always unmanaged; thus,
+.B XtMakeGeometryRequest
+always returns
+.B XtGeometryYes
+when called by a child of a primitive widget.
+.LP
+The
+.B XtMakeResizeRequest
+function, a simple interface to
+.BR XtMakeGeometryRequest ,
+creates a
+.B XtWidgetGeometry
+structure and specifies that width and height should change.
+The geometry manager is free to modify any of the other window attributes
+(position or stacking order) to satisfy the resize request.
+If the return value is
+.BR XtGeometryAlmost ,
+width_return and height_return contain a compromise width and height.
+If these are acceptable,
+the widget should immediately make an
+.B XtMakeResizeRequest
+and request that the compromise width and height be applied.
+If the widget is not interested in
+.B XtGeometryAlmost
+replies,
+it can pass NULL for width_return and height_return.
