Action when closing a window

[Wolfgang Ciriack]

Hello,
how can i assign a action to closing a window, someting like ON CLOSE ?
Can i decide with the return value of this action to close the window or to stay in the window ?

Wolfang,

Use the VALID clause:

ACTIVATE WINDOW oWnd VALID MsgYesNo( "Want to end ?" )

the expression used with VALID has to return a logical value
