NAME

6       XtMakeGeometryRequest, XtMakeResizeRequest - make geometry manager
7       request
8

SYNTAX

10       XtGeometryResult XtMakeGeometryRequest(Widget w, XtWidgetGeometry
11              *request, XtWidgetGeometry *reply_return);
12
13       XtGeometryResult XtMakeResizeRequest(Widget w, Dimension width, height,
14              Dimension *width_return, Dimension *height_return);
15

ARGUMENTS

17       reply_return
18                 Returns the allowed widget size or may be NULL if the
19                 requesting widget is not interested in handling XtGeometryAl‐
20                 most.
21
22       request   Specifies the desired widget geometry (size, position, border
23                 width, and stacking order).
24
25       w         Specifies the widget that is making the request.
26
27       width_return
28       height_return
29                 Return the allowed widget width and height.

DESCRIPTION

32       Depending on the condition, XtMakeGeometryRequest performs the follow‐
33       ing:
34
35       ·    If the widget is unmanaged or the widget's parent is not realized,
36            it makes the changes and returns XtGeometryYes.
37
38       ·    If the parent is not a subclass of compositeWidgetClass or the
39            parent's geometry_manager is NULL, it issues an error.
40
41       ·    If the widget's being_destroyed field is True, it returns XtGeome‐
42            tryNo.
43
44       ·    If the widget x, y, width, height and border_width fields are all
45            equal to the requested values, it returns XtGeometryYes; other‐
46            wise, it calls the parent's geometry_manager procedure with the
47            given parameters.
48
49       ·    If the parent's geometry manager returns XtGeometryYes and if
50            XtCWQueryOnly is not set in the request_mode and if the widget is
51            realized, XtMakeGeometryRequest calls the XConfigureWindow Xlib
52            function to reconfigure the widget's window (set its size, loca‐
53            tion, and stacking order as appropriate).
54
55       ·    If the geometry manager returns XtGeometryDone, the change has
56            been approved and actually has been done.  In this case, XtMake‐
57            GeometryRequest does no configuring and returns XtGeometryYes.
58            XtMakeGeometryRequest never returns XtGeometryDone.
59
60       Otherwise, XtMakeGeometryRequest returns the resulting value from the
61       parent's geometry manager.
62
63       Children of primitive widgets are always unmanaged; thus, XtMake‐
64       GeometryRequest always returns XtGeometryYes when called by a child of
65       a primitive widget.
66
67       The XtMakeResizeRequest function, a simple interface to XtMakeGeometry‐
68       Request, creates a XtWidgetGeometry structure and specifies that width
69       and height should change.  The geometry manager is free to modify any
70       of the other window attributes (position or stacking order) to satisfy
71       the resize request.  If the return value is XtGeometryAlmost,
72       width_return and height_return contain a compromise width and height.
73       If these are acceptable, the widget should immediately make an XtMake‐
74       ResizeRequest and request that the compromise width and height be
75       applied.  If the widget is not interested in XtGeometryAlmost replies,
76       it can pass NULL for width_return and height_return.
