Example: Check social security entries
Suppose you have an application like the following:
This application has a window as its parent part. And it has the following child parts:
• An Add Data push button

4. Click on the window.
5. From the displayed pop-up menu, select All Features.
6. From the displayed window, select the attribute self and then OK.
Now, complete steps similar to steps 2 through 6 to make three more connections:
• Connect the clicked event of the push button to the check action of the Form Input Checker.
• Connect the checkFailed event of the Form Input Checkerto its showErrorToUser action. (This connection appears as a green, triangle-shaped arrow on the Form Input Checker part.)
• Connect the checkSucceeded event of the Form Input Checker to the closeWidget action of the window.
Finally, run the application. If you enter nine digits in the text pane and click on Add Data, the window closes. If you enter invalid data for the Social Security Number type--such as letters--and click on Add Data, a message box saying "Invalid Social Security Number" is displayed.
