As shown previously, the Graphics Composer Event Manager, Events sub-tab supports screen events when the screen is visible (On Show) and hidden (On Hide). These events can define event handlers based on Template actions or Custom, user-defined code.

Not all widgets can generate an event. For example, a Label Widget has nothing to generate, it just sits there on the screen, labeling. Here is a list of the widgets that can generate an event:

• Button – Pressed and Released events
• Check Box – Checked and Unchecked events
• Draw Surface – Draw Notification event
• Image Sequence – Image Changed event
• Key Pad – Key Click event
• List Wheel – Select Item Changed event
• List – Selection Changed event
• Progress Bar – Value Changed event
• Radio Button – Selected and Deselected event
• Scroll Bar – Value Changed event
• Slider Widget – Value Changed event
• Text Field – Text Changed event
• Touch Test – Point Added event
