js editor
Web development
Places a menu definition on a stack of menu definitions in memory.
PUSH POPUP MenuName |
Parameters
- MenuName
- Specifies the name of the menu whose definition is placed on the stack. The menu can also be a Visual FoxPro system menu.
Remarks
When used with POP POPUP, PUSH POPUP makes it possible for you to save a menu definition, make changes to the menu definition, and then restore the menu definition to its original state.
Menu definitions are placed on and removed from the stack in last-in, first-out order. Menu definitions take up memory, so every PUSH POPUP should have a corresponding POP POPUP to make sure your application's memory usage does not grow unnecessarily.
Example
In the following example, a menu named popExam is created. The menu definition is pushed to the stack and then modified. The original menu is then restored by popping it off the stack.
