Connecting the Open To-Do File button

Now that you have added all the new beans to the free-form surface, you are ready to begin connecting them.

The To-Do List applet should call the readToDoFile() method when a user selects the Open To-Do File button. To implement this, you must connect ReadButton to the readToDoFile() method.

  1. Select ReadButton and click mouse button 2.
  2. Select Connect and then actionPerformed from the pop-up menu that appears.
  3. Click mouse button 1 on the free-form surface and select Event to Code.
  4. In the Event to Code window, select readToDoFile() from the Method list and then select OK. The free-form surface should look like this:

  5. Save your current work in the Visual Composition Editor by selecting Save Bean from the Bean menu. VisualAge for Java generates code to implement the connections you just specified.

Congratulations! You have implemented the Open To-Do File button. Now you are ready to test the work you have done so far on the To-Do List program.
