XtMakeGeometryRequest, XtMakeResizeRequest - make geometry
manager request
SYNTAX
XtGeometryResult XtMakeGeometryRequest(w, request,
reply_return)
Widget w;
XtWidgetGeometry *request;
XtWidgetGeometry *reply_return;
XtGeometryResult XtMakeResizeRequest(w, width, height,
width_return, height_return)
Widget w;
Dimension width, height;
Dimension *width_return, *height_return
ARGUMENTS
reply_return
Returns the allowed widget size or may be NULL
if the requesting widget is not interested in
handling XtGeometryAlmost.
request Specifies the desired widget geometry (size,
position, border width, and stacking order).
w Specifies the widget that is making the request.
width_return
height_return
Return the allowed widget width and height.
DESCRIPTION
Depending on the condition, XtMakeGeometryRequest performs
the following:
o If the widget is unmanaged or the widget's parent is
not realized, it makes the changes and returns
XtGeometryYes.
o If the parent is not a subclass of compositeWidget-
Class or the parent's geometry_manager is NULL, it
issues an error.
o If the widget's being_destroyed field is True, it
returns XtGeometryNo.
o If the widget x, y, width, height and border_width
fields are all equal to the requested values, it
returns XtGeometryYes; otherwise, it calls the par-
ent's geometry_manager procedure with the given
parameters.
o If the parent's geometry manager returns

XtGeometryYes and if XtCWQueryOnly is not set in the
request_mode and if the widget is realized, XtMake-
GeometryRequest calls the XConfigureWindow Xlib func-
tion to reconfigure the widget's window (set its
size, location, and stacking order as appropriate).
o If the geometry manager returns XtGeometryDone, the
change has been approved and actually has been done.
In this case, XtMakeGeometryRequest does no configur-
ing and returns XtGeometryYes. XtMakeGeometryRequest
never returns XtGeometryDone.
Otherwise, XtMakeGeometryRequest returns the resulting
value from the parent's geometry manager.
Children of primitive widgets are always unmanaged; thus,
XtMakeGeometryRequest always returns XtGeometryYes when
called by a child of a primitive widget.
The XtMakeResizeRequest function, a simple interface to
XtMakeGeometryRequest, creates a XtWidgetGeometry struc-
ture 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
XtGeometryAlmost, width_return and height_return contain a
compromise width and height. If these are acceptable, the
widget should immediately make an XtMakeResizeRequest and
request that the compromise width and height be applied.
If the widget is not interested in XtGeometryAlmost
replies, it can pass NULL for width_return and
height_return.
