PUSH POPUP Command
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.
DEFINE POPUP popExam FROM 5,5
DEFINE BAR 1 OF popExam PROMPT 'One'
DEFINE BAR 2 OF popExam PROMPT 'Two'
DEFINE BAR 3 OF popExam PROMPT 'Three'
DEFINE BAR 4 OF popExam PROMPT 'Four'
