Menu item events – PB Docs 2022

• 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 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

• 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.
