XtMakeGeometryRequest(3) XT FUNCTIONS XtMakeGeometryRequest(3)
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
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
compositeWidgetClass 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 parent'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,
XtMakeGeometryRequest calls the
XConfigureWindow Xlib function 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 configuring 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 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
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.
