XtMakeGeometryRequest(3Xt)XtMakeGeometryRequest(3Xt)NAME
XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager
request
SYNOPSIS
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
Returns the allowed widget size or may be NULL if the requesting widget
is not interested in handling XtGeometryAlmost. Specifies the desired
widget geometry (size, position, border width, and stacking order).
Specifies the widget that is making the request. Return the allowed
widget width and height.
DESCRIPTION
Depending on the condition, XtMakeGeometryRequest performs the follow‐
ing: 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 pro‐
cedure with the given parameters. 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). 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, XtMakeGeome‐
tryRequest always returns XtGeometryYes when called by a child of a
primitive widget.
The XtMakeResizeRequest function, a simple interface to XtMakeGeome‐
tryRequest, 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 sat‐
isfy 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 XtMak‐
eResizeRequest 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.
