XtMakeGeometryRequest(3) XT FUNCTIONS XtMakeGeometryRequest(3)
NAME
XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager re-
quest
SYNTAX
#include <X11/Intrinsic.h>
XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry *re-
quest, XtWidgetGeometry *reply_return);
XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width, Dimen-
sion height, Dimension *width_return, Dimension *height_return);
ARGUMENTS
reply_return
Returns the allowed widget size or may be NULL if the re-
questing widget is not interested in handling XtGeometryAl-
most.
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 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 XtGeome-
tryNo.
• If the widget x, y, width, height and border_width fields are all
equal to the requested values, it returns XtGeometryYes; other-
wise, it calls the parent's geometry_manager procedure 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, loca-
tion, and stacking order as appropriate).
• If the geometry manager returns XtGeometryDone, the change has
been approved and actually has been done. In this case, XtMake-
GeometryRequest 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, XtMake-
GeometryRequest 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_re-
turn and height_return contain a compromise width and height. If these
are acceptable, the widget should immediately make an XtMakeResize-
Request 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.
