XtMakeGeometryRequest
NAME
XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager request
SYNTAX
XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry
*request, XtWidgetGeometry *reply_return);
XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width,
height, Dimension *width_return, Dimension *height_return);
ARGUMENTS
reply_return
Returns the allowed widget size or may be NULL
if the requesting widget is not interested in handling
request
Specifies the desired widget geometry (size, position, border width,
and stacking order).
w
Specifies the widget .
width_return
height_return
Return the allowed widget width and height.
DESCRIPTION
Depending on the condition,
performs the following:
If the widget is unmanaged or the widget's parent is not realized,
it makes the changes and returns
If the parent is not a subclass of
or the parent's geometry_manager is NULL,
it issues an error.
If the widget's being_destroyed field is
it returns
If the widget x, y, width, height and border_width fields are
all equal to the requested values,
it returns
otherwise, it calls the parent's geometry_manager procedure
with the given parameters.
If the parent's geometry manager returns
and if
is not set in the request_mode
and if the widget is realized,
calls the
Xlib function to reconfigure the widget's window (set its size, location,
and stacking order as appropriate).
If the geometry manager returns
the change has been approved and actually has been done.
In this case,
does no configuring and returns
never returns
Otherwise,
returns the resulting value from the parent's geometry manager.
Children of primitive widgets are always unmanaged; thus,
always returns
when called by a child of a primitive widget.
The
function, a simple interface to
creates a
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
width_return and height_return contain a compromise width and height.
If these are acceptable,
the widget should immediately make an
and request that the compromise width and height be applied.
If the widget is not interested in
replies,
it can pass NULL for width_return and height_return.
