Event handling

All the time when you interact with User Interface different events occur. According to occurred events, the appropriate event-handling code is executed. To define what event occurs you need to add the related event handlers.

To get a list of available events you should make the following steps:

• In the Components tree select a component which related events you wish to get.
• From the bottom bar of the Properties/events pane click on the Events item.
  
  To add event handler:
• Check an event you wish to handle.
• After you check an event, a window with the initial event-handling code will be opened.
• In the opened window write the desired event-handling code and click the button Save to save changes or Cancel to cancel them.
  
  To edit event handler:
• In a row with the appropriate event, click on the Edit item. A window with the event-handling code will be opened.
• In the opened window write the desired code and click the button Save to save changes or Cancel to cancel them.
  
  To delete event handler:
• Uncheck an event which handler you wish to delete.
