All the mega-widget classes in Tix, such as TixComboBox and
|
|
TixControl, are implemented in the Tix Intrinsics framework. Also,
|
|
you can write new <em>widget classes</em> with the Tix Intrinsics. In
|
|
the next section, I'll go through all the steps of creating a new
|
|
widget class in Tix. I'll illustrate the idea using a new class
|
|
``TixArrowButton'' as an example. TixArrowButton is essentially a
|
|
button that can display an arrow in one of the for directions
|
|
(see figure 6-1).

|
Once you have defined your classes, you can create <em>widget
|
|
instances</em> of these classes. For example, the following code will
|
|
create four instances of your new TixArrowButton class:

|
|
<blockquote> <P><tt> tixArrowButton .up -direction n<BR>
|
|
tixArrowButton .left -direction e<BR>
|
|
tixArrowButton .right -direction w<BR>
|
|
tixArrowButton .down -direction s
|
|
</tt>
