To add a statement to your openFile script that changes the
window title, use the Subpart Features Syntax tool,
.
To set the title to the file name that the user selected, add the following statement to the end of your script:
(self subpartNamed: 'Window') title: file.
Because connections are also VisualAge parts, you can add event-to-script connections to a connection. Add the following new script to the fileSelection category and make it run when the result event occurs:
beep "beeps just to try out event-to-script connections" CgDisplay default bell: 20.
Create the connection by clicking mouse button 2 (mouse button 3 on UNIX systems) on the event-to-script connection line that you already created, and then select Connect > normalResult. Click mouse button 1 on the free-form surface. Select Event to Script from the pop-up menu. Select beep from the method list and then select OK.
If you have made the connection properly, you should see a new connection line from the middle of your first connection to an icon representing the beep script. When you test your view, you should hear a beep when the file is opened.
When creating an "attribute changed" event-to-script connection, do not try to use an attribute-to-attribute connection to the changing attribute to pass a parameter on the event-to-script connection. The attribute might not actually be changed yet. Use the value that is passed as a parameter on the event notification instead.
Try moving the beep script created above to a new category. Select the beep script and then select Categorize > Change Categories from the method list pop-up menu. Select <new category> in the Selection Required window and then select OK. In the prompter window, type in aNewCategory and select OK. Now, test your window again. VisualAge maintains all connections when a script is moved.
Try moving the beep script back to the fileSelection category. VisualAge shows you that the category aNewCategory is now empty.
