XtRealizeWidget, XtIsRealized, XtUnrealizeWidget \- realize and unrealize widgets
|
|
.SH SYNTAX
|
|
.HP
|
|
void XtRealizeWidget(Widget \fIw\fP);
|
|
.HP
|
|
Boolean XtIsRealized(Widget \fIw\fP);
|
|
.HP
|
|
void XtUnrealizeWidget(Widget \fIw\fP);
|
|
.SH ARGUMENTS
|
|
.IP \fIw\fP 1i
|
|
Specifies the widget.
|
|
.SH DESCRIPTION
|
|
If the widget is already realized,
|
|
.ZN XtRealizeWidget
|
|
simply returns.
|
|
Otherwise, it performs the following:
|
|
.IP \(bu 5
|
|
Binds all action names in the widget's
|
|
translation table to procedures (see Section 10.1.2).
|
|
.IP \(bu 5
|
|
Makes a post-order traversal of the widget tree rooted
|
|
at the specified widget and calls the change_managed procedure
|
|
of each composite widget that has one or more managed children.
|
|
.IP \(bu 5
|
|
Constructs an
|
|
.ZN XSetWindowAttributes
|
|
structure filled in with information derived from the
|
|
.ZN Core
|
|
widget fields and calls the realize procedure for the widget,
|
|
which adds any widget-specific attributes and creates the X window.
|
|
.IP \(bu 5
|
|
If the widget is
|
|
not a subclass of
|
|
.ZN compositeWidgetClass ,
|
|
.ZN XtRealizeWidget
|
|
returns; otherwise, it continues and performs the following:
|
|
.RS
|
|
.IP \- 5
|
|
Descends recursively to each of the widget's
|
|
managed children and calls the realize procedures.
|
|
Primitive widgets that instantiate children are responsible for realizing
|
|
those children themselves.
|
|
.IP \- 5
|
|
Maps all of the managed children windows that have mapped_when_managed
|
|
.ZN True .
|
|
(If a widget is managed but mapped_when_managed is
|
|
.ZN False ,
|
|
the widget is allocated visual space but is not displayed.
|
|
Some people seem to like this to indicate certain states.)
|
|
.RE
|
|
.LP
|
|
If the widget is a top-level shell widget (that is, it has no parent), and
|
|
mapped_when_managed is
|
|
.ZN True ,
|
|
.ZN XtRealizeWidget
|
|
maps the widget window.
|
|
.LP
|
|
The
|
|
.ZN XtIsRealized
|
|
function returns
|
|
.ZN True
|
|
if the widget has been realized,
|
|
that is, if the widget has a nonzero X window ID.
|
|
.LP
|
|
Some widget procedures (for example, set_values) might wish to
|
|
operate differently
|
|
after the widget has been realized.
|
|
.LP
|
|
The
|
|
.ZN XtUnrealizeWidget
|
|
function destroys the windows of an existing widget and all of its
|
|
children (recursively down the widget tree).
|
|
To recreate the windows at a later time,
|
|
call
|
|
.ZN XtRealizeWidget
|
|
again.
|
|
If the widget was managed,
|
|
it will be unmanaged automatically before its window is freed.
