XtMakeGeometryRequest(3Xt) XT FUNCTIONS XtMakeGeometryRequest(3Xt)
NAME
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:
+ If the widget is unmanaged or the widget's parent is not realized, it
makes the changes and returns XtGeometryYes.
+ If the parent is not a subclass of compositeWidgetClass or the
parent's geometry_manager is NULL, it issues an error.
+ If the widget's being_destroyed field is True, it returns
XtGeometryNo.
+ 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 parame-
ters.
+ 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 func-
tion to reconfigure the widget's window (set its size, location, and
stacking order as appropriate).
+ If the geometry manager returns XtGeometryDone, the change has been
approved and actually has been done. In this case, XtMakeGeometry-
Request does no configuring and returns XtGeometryYes. XtMake-
GeometryRequest never returns XtGeometryDone.
Otherwise, XtMakeGeometryRequest returns the resulting value from the
parent's geometry manager.
Children of primitive widgets are always unmanaged; thus, XtMakeGeometry-
Request always returns XtGeometryYes when called by a child of a primitive
widget.
The XtMakeResizeRequest function, a simple interface to XtMakeGeometry-
Request, 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 accept-
able, 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.
