Menu items have the following events:
Clicked Typically, your application will contain Clicked scripts for each menu item in a drop-down or cascading menu. For example, the script for the Clicked event for the Open menu item on the File menu opens a file.
Help You can provide Help on a menu item when a user presses the F1 key, or when the user clicks the context Help button [?] on the title bar of the window with which the menu is associated, and then clicks on a menu item.
Selected You will probably use few Selected scripts since users do not expect things to happen when they simply highlight a menu item. One use of Selected scripts is to change MicroHelp displayed in an MDI application as the user scrolls through a menu.
The Clicked event is triggered whenever:
The user clicks the menu item
The user selects (highlights) the menu item using the keyboard and then presses ENTER
The user presses the shortcut key for the menu item
The menu containing the menu item is displayed and the user presses the accelerator key Alt+key.
When a script executes the PopMenu function and displays a pop-up menu
A menu item responds to a mouse-click or the keyboard only if both its Visible and Enabled properties are set to “true”.
If the menu item has a drop-down or cascading menu under it, the script for its Clicked event (if any) is executed when the mouse button is pressed, and then the drop-down or cascading menu displays. If the menu item does not have a menu under it, the script for the Clicked event is executed when the mouse button is released.
Using the Clicked event to specify menu item properties
When the user clicks an item on the menu bar to display a
drop-down menu, the Clicked event for the menu item on the menu
bar is triggered and then the drop-down menu is displayed.
You can use the menu bar's Clicked event to specify the properties of the menu items in the drop-down menu. For example, if you want to disable items in a drop-down menu, you can disable them in the script for the Clicked event for the menu item in the menu bar.
The Help event is triggered when the user presses F1or clicks the context Help button [?] on a window’s title bar and then points and clicks on a menu item.
The Selected event is triggered when the user selects a menu item.
