Special Aspects for Menus with a Default Button

• If the menu arrow is clicked, event menu_button is triggered.
• If the default button is clicked, event user_command is triggered.

For both events, the system passes the function code that you assigned in the function field. So if you want to assign a menu function to the default button, the function code for the menu must be identical to that of the menu function. In the MENU_BUTTON event, you then build the menu, while in the USER_COMMAND event, you can directly query the function code for the default function.
