<p>
|
|
|
|
<p> The <a href="ntqaction.html">TQAction</a> class provides a way of associating user input from different
|
|
|
|
user interface elements with abstract high level actions. This approach makes
|
|
|
|
it easy to customize applications for different types of users.
|
|
|
|
<p> This example program is just like the
|
|
|
|
<a href="simple-application-example.html">application example</a>,
|
|
|
|
but uses TQAction to build the menu and the toolbar.
