hello all, I'm trying to put together a function to mdi windows, where I can pass the object and a baction as parameters, so that when opened by a User registration screen and not close, and try to open again, just bring that window already mdi created.

REDEFINE BUTTON BTNCAD ID 50 OF OWNDPRINCIPAL ACTION ( Abremdi ("clients", {| | Register ()) )

Abremdi function (OWND, bAction)

IF &OWND == NIL
EVAL (baction)
ELSE
&OWND: SetFocus ()
ENDIF
RETURN (. T.)

most always returns the last variable in OWND not exist.
if anyone has any function for treatment of mdi can share and appreciate.

This is the way I do:

Code: Select all

STATIC nJane
STATIC oWndCh

FUNCTION MyFunction

IF nJane != 1
    DEFINE WINDOW oWndCh CHILD OF wndMain()
    
    ACTIVATE WINDOW oWndCh VALID ( nJane := NIL, .T. ) ON INIT ( nJane := 1 )
ELSE
    oWndCh:Restore()
ENDIF
RETURN ( NIL )
