ChangeMenu

PowerScript function

Description

Changes the menu associated with a window. If the window is an MDI
frame window, ChangeMenu appends the list of open sheets to the currently
active menu.

Applies to

Window objects

Syntax

Argument

Description

windowname

The name of the window for which you want to change the
menu.

menuname

The name of the menu you want to make the current
menu.

position (MDI frame windows only)

The number of the item on the menu bar to which you want
to append the names of the open sheets. Items on the menu bar
are numbered from the left, beginning with 1. The default is 0,
which lists the open sheets on the menu bar’s next-to-last menu
(or the last menu if there is only one available).

Return value

Integer.

Returns 1 if it succeeds and -1 if an error occurs. If any
argument’s value is null, ChangeMenu returns null. The return value is
usually not used.

Usage

If you are changing the menu associated with an MDI frame window,
the new menu will not be visible if an open sheet with its own menu is
active. When a sheet has its own menu, the list of open sheets appears on
its menu, as well as on the hidden menu for the frame.

In an MDI frame window, if you change to a menu with a different
menu and toolbar style (traditional or contemporary), the style of the
menu changes but the style of the toolbar does not.

Examples

This statement changes the top-level menu of the w_Employee window
to m_Emp1:
