CURRENT-WINDOW system handle

A handle to the default window for the current ABL session. This window is the default parent for all frames, dialog boxes, alert boxes, and messages. Set or examine the attributes of the CURRENT-WINDOW handle to modify or get information on the current default window.

Syntax 

 

CURRENT-WINDOW [ :attribute ]

attribute

An attribute of the CURRENT-WINDOW.

Attributes

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

Notes 

The default value of the CURRENT-WINDOW handle is the static session window referenced by the DEFAULT-WINDOW handle. You can change the default window for the current session by assigning the handle of a window to CURRENT WINDOW.

The IN WINDOW phrase allows you to explicitly assign a window as a parent for a frame, dialog box, alert box, or message.

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 CURRENT-WINDOW attribute of a procedure allows you to specify a default window for the procedure block. The CURRENT-WINDOW attribute of a procedure overrides the CURRENT-WINDOW handle for the procedure block.

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

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

You can make the current window visible or invisible by changing the value of CURRENT-WINDOW:VISIBLE.

Because CURRENT-WINDOW is the general default parent for ABL frames, you cannot set CURRENT-WINDOW to the handle of a .NET form’s shadow window. If allowed, this would make the associated .NET form a default parent for ABL frames, and ABL cannot parent ABL frames to .NET forms. A .NET form’s shadow window handle is provided by the ProWinHandle property of the Progress.Windows.Form class, which an OpenEdge .NET class designed for instantiating .NET forms in an ABL session. Therefore, any attempt to set CURRENT-WINDOW to a ProWinHandle property value raises a run-time error.
