<H3><A NAME="M19">DESCRIPTION</A></H3>
|
|
The <B>toplevel</B> procedure creates a new toplevel widget (given
|
|
by the <I>widget-name</I> argument). Additional
|
|
options, described above, may be specified on the procedure line
|
|
or in the option database
|
|
to configure aspects of the toplevel such as its background color
|
|
and relief. The <B>toplevel</B> procedure returns the
|
|
path name of the new window.
|
|
<P>
|
|
A toplevel is similar to a frame except that it is created as a
|
|
top-level window: its X parent is the root window of a screen
|
|
rather than the logical parent from its path name. The primary
|
|
purpose of a toplevel is to serve as a container for dialog boxes
|
|
and other collections of widgets. The only visible features
|
|
of a toplevel are its background color and an optional 3-D border
|
|
to make the toplevel appear raised or sunken.
|
|
|
|
<H3><A NAME="M20">WIDGET PROCEDURE</A></H3>
|
|
The <B>toplevel</B> procedure creates a new STk procedure whose
|
|
name is the same as the path name of the toplevel's window. This
|
|
procedure may be used to invoke various
|
|
operations on the widget. It has the following general form:
|
|
<PRE>(<I>widget-name option </I>?<I>arg arg ...</I>?)</PRE>
|
|
<I>PathName</I> is the name of the procedure, which is the same as
|
|
the toplevel widget's path name. <I>Option</I> and the <I>arg</I>s
|
|
determine the exact behavior of the procedure. The following
|
|
procedures are possible for toplevel widgets:
|
|
<P>
|
|
<DL>
|
|
<DT><A NAME="M21">(<I>widget-name '</I><B>cget</B> <I>option</I>)</A><DD>
|
|
Returns the current value of the configuration option given
|
|
by <I>option</I>.
|
|
<I>Option</I> may have any of the values accepted by the <B>toplevel</B>
|
|
procedure.
|
|
<P>
|
|
<DT><A NAME="M22">(<I>widget-name '</I><B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?)</A><DD>
|
|
Query or modify the configuration options of the widget.
|
|
If no <I>option</I> is specified, returns a list describing all of
|
|
the available options for <I>widget-name</I> (see <B>Tk_ConfigureInfo</B> for
|
|
information on the format of this list). If <I>option</I> is specified
|
|
with no <I>value</I>, then the procedure returns a list describing the
|
|
one named option (this list will be identical to the corresponding
|
|
sublist of the value returned if no <I>option</I> is specified). If
|
|
one or more <I>option-value</I> pairs are specified, then the procedure
|
|
modifies the given widget option(s) to have the given value(s); in
|
|
this case the procedure returns an empty string.
|
|
<I>Option</I> may have any of the values accepted by the <B>toplevel</B>
|
|
procedure.
|
|
|
|
<P>

<H3><A NAME="M23">BINDINGS</A></H3>
|
|
When a new toplevel is created, it has no default event bindings:
|
|
toplevels are not intended to be interactive.
