Creating a tab button through a script
Typically, you will want to create Scripts within a profile Package.
If you apply a Script to a diagram type, you will not be able to use that diagram type's standard diagram tab with any diagrams of that type. If this is a problem, use a Stereotype to apply the button to specific diagrams. See Creating a toolbar button through a stereotype.

8. If you want the customized button to be part of a group of buttons, type the value of the group in the Group box. All buttons that appear on the tab and have the same group value will appear as buttons of the same split button, such as, the Dependency buttons on the Class Diagram tab.

10. In the Status Bar Text box, type the text you want to appear in the status bar when you rest the mouse pointer over the button. If you want to use the status bar text of the button on which the customized button is based, leave the Status Bar Text box blank.
11. If you want the customized button to use an icon that is different from that of the button on which it is based, click the Edit button, and then select the icon you want to use.
12. If you want the customized button to be added to the target diagram's tab buttons, rather than replacing all the target tab’s buttons, select the Additive check box.

14. Click the Script tab.
15. In the box, type the script you want to run after the button has been used to add an item to a diagram.
