VISIBLE

Applies to

All controls.

Description

Returns or sets visibility status of specified control. If true, the control is visible at run-time. If false, the control is invisible at run-time

Usage

visiblestate = Get_Property (objectname, "VISIBLE")

existingstate = Set_Property (objectname, "VISIBLE", visiblestate)

Remarks

The visiblestate value passed to Set_Property() can be any of the valid show-window states, (those states accepted by the Windows API function ShowWindow). For example, the Windows SDK file "windows.h" defines SW_RESTORE as 9; this value restores a minimized window to its previous size, equivalent to the "Restore" choice on the Window's system menu.

Note: To hide a menu item, set its visible property to 0. A top level menu (on the menu bar) cannot be hidden this way. To hide it, set its TEXT property to null.

Returns

Values returned by Get_Property and Set_Property:
