.SH DESCRIPTION
|
||
|
|
Depending on the condition,
|
||
|
|
.ZN 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
|
||
|
|
.ZN XtGeometryYes .
|
||
|
|
.IP \(bu 5
|
||
|
|
If the parent is not a subclass of
|
||
|
|
.ZN compositeWidgetClass
|
||
|
|
or the parent's geometry_manager is NULL,
|
||
|
|
it issues an error.
|
||
|
|
.IP \(bu 5
|
||
|
|
If the widget's being_destroyed field is
|
||
|
|
.ZN True ,
|
||
|
|
it returns
|
||
|
|
.ZN XtGeometryNo .
|
||
|
|
.IP \(bu 5
|
||
|
|
If the widget x, y, width, height and border_width fields are
|
||
|
|
all equal to the requested values,
|
||
|
|
it returns
|
||
|
|
.ZN XtGeometryYes ;
|
||
|
|
otherwise, it calls the parent's geometry_manager procedure
|
||
|
|
with the given parameters.
|
||
|
|
.IP \(bu 5
|
||
|
|
If the parent's geometry manager returns
|
||
|
|
.ZN XtGeometryYes
|
||
|
|
and if
|
||
|
|
.ZN XtCWQueryOnly
|
||
|
|
is not set in the request_mode
|
||
|
|
and if the widget is realized,
|
||
|
|
.ZN XtMakeGeometryRequest
|
||
|
|
calls the
|
||
|
|
.ZN 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
|
||
|
|
.ZN XtGeometryDone ,
|
||
|
|
the change has been approved and actually has been done.
|
||
|
|
In this case,
|
||
|
|
.ZN XtMakeGeometryRequest
|
||
|
|
does no configuring and returns
|
||
|
|
.ZN XtGeometryYes .
|
||
|
|
.ZN XtMakeGeometryRequest
|
||
|
|
never returns
|
||
|
|
.ZN XtGeometryDone .
|
||
|
|
.LP
|
||
|
|
Otherwise,
|
||
|
|
.ZN XtMakeGeometryRequest
|
||
|
|
returns the resulting value from the parent's geometry manager.
|
||
|
|
.LP
|
||
|
|
Children of primitive widgets are always unmanaged; thus,
|
||
|
|
.ZN XtMakeGeometryRequest
|
||
|
|
always returns
|
||
|
|
.ZN XtGeometryYes
|
||
|
|
when called by a child of a primitive widget.
|
||
|
|
.LP
|
||
|
|
The
|
||
|
|
.ZN XtMakeResizeRequest
|
||
|
|
function, a simple interface to
|
||
|
|
.ZN XtMakeGeometryRequest ,
|
||
|
|
creates a
|
||
|
|
.ZN 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
|
||
|
|
.ZN XtGeometryAlmost ,
|
||
|
|
width_return and height_return contain a compromise width and height.
|
||
|
|
If these are acceptable,
|
||
|
|
the widget should immediately make an
|
||
|
|
.ZN XtMakeResizeRequest
|
||
|
|
and request that the compromise width and height be applied.
|
||
|
|
If the widget is not interested in
|
||
|
|
.ZN XtGeometryAlmost
|
||
|
|
replies,
|
||
|
|
it can pass NULL for width_return and height_return.
