ACTIVE-WINDOW system handle

A handle to the last ABL application window to receive an ENTRY event. You cannot set the ACTIVE-WINDOW handle, but you can read and write values for the attributes of the ACTIVE-WINDOW.

Syntax 

 

ACTIVE-WINDOW [ :attribute ]

attribute

An attribute of the ACTIVE-WINDOW.

Attributes

The ACTIVE-WINDOW handle has all the attributes of a window widget.

Notes 

In a character interface, the ACTIVE-WINDOW, CURRENT-WINDOW, and DEFAULT-WINDOW handles return the handle of the static window for the current ABL session.

The initial value of the ACTIVE-WINDOW handle is the CURRENT-WINDOW handle.

The ACTIVE-WINDOW handle monitors the active window in the ABL session only. It does not monitor the active window for the window system. Accessing a non‑ABL window does not affect the state of the ACTIVE-WINDOW handle.

You can enable or disable the current window by changing ACTIVE-WINDOW:SENSITIVE.

You can set the menu bar for the active window by assigning the handle of a menu bar to ACTIVE-WINDOW:MENUBAR.
