|
|
A composite widget is made by assembling several widgets (simple
|
|
or even composite widgets):
|
|
</font>
|
|
|
|
<pre>
|
|
(define le (make <Labeled-entry> :value 50 :title "Valeur:"))
|
|
</pre>
|
|
|
|
<font size=+4>
|
|
defines <tt>le</tt> as an instance of the <tt><Labeled-entry></tt>
|
|
class. This object, on a screen, gives:
|
|
<p>
|
|
<center>
|
|
<IMG SRC="Images/compo-all.gif"><P>
|
|
</center>
|
|
<pre>
|
|
|
|
|
|
</pre>
|
|
In fact, this widget is composed if three Tk basic widgets: a
|
|
<i>frame</i>, a <i>label</i> an an <i>entry</i>:
|
|
<pre>
|
|
|
|
</pre>
|
|
<center>
|
|
<IMG SRC=Images/frame.gif> + <IMG SRC=Images/label.gif> + <IMG SRC=Images/entry.gif><P>
|
|
</center>
|
|
|
|
<pre>
|
|
|
|
</pre>
|
|
<ul>
|
|
<li> A demonstration of some composite widgets can be launched from here with:
|
|
<ul>
|
|
<li> the non-installed version of STk
|
|
(<a expr=(system "test-stk -f stklos-widgets.stklos&")><tt>test-stk</tt></a>)
|
|
<li> the installed version of STk
|
|
(<a expr=(system "stk -f stklos-widgets.stklos &")><tt>stk</tt></a>)<p>
|
|
</ul>
|
|
<li> The complete <a href="Lentry.stklos">code</a> of the <tt><Labeled-entry></tt> class is approximatively 60 lines.

</ul>
