How to implement GETACTIVE()?

[Enrico Maria Giordano]

I need to implemente a generic GETACTIVE() function (just like the old Clipper one). Any suggestion? This is a sample of what I need:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVr1 := SPACE( 30 )
    LOCAL cVr2 := SPACE( 30 )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVr1 VALID !EMPTY( GETACTIVE():VarGet() )  // !EMPTY( cVr1 )
    @ 3, 1 GET cVr2

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL

Something like that?

Code: Select all  Expand view

Function GetActive( oDlg )

   local oObj
   local x
   For x = 1 to Len( oDlg:aControls )
      if oDlg:aControls[ x ]:HasFocus()
         oObj  := oDlg:aControls[ x ]
         Exit
      endif
   Next x
/*
   AEVal( oDlg:aControls, { | o | if( o:HasFocus(), oObj := o, ) } )
*/
/*
   hb_ForNext( 1, Len( oDlg:aControls ), { | i | if( oDlg:aControls[ i ]:HasFocus(), oObj := oDlg:aControls[ i ],  ) }, 1 )
*/

Return oObj

Thank you. Unfortunately, it doesn't work as the focused GET is the next, not the current. Try this sample:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVr1 := SPACE( 30 )
    LOCAL cVr2 := SPACE( 30 )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVr1 VALID !EMPTY( GETACTIVE( oDlg ):VarGet() )
    @ 3, 1 GET cVr2

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL


FUNCTION GETACTIVE( oDlg )

    LOCAL i

    FOR i = 1 TO LEN( oDlg:aControls )
        IF oDlg:aControls[ i ]:HasFocus()
            RETURN oDlg:aControls[ i ]
        ENDIF
    NEXT

    RETURN NIL

Try

Code: Select all  Expand view

    FOR i = 1 TO LEN( oDlg:aControls )
        IF oDlg:aControls[ i ]:HasFocus()
            RETURN oDlg:aControls[ i - if( i = 1, 0, 1 ) ]
        ENDIF
    NEXT

No, it cannot work, sorry. First, because it is a generic function, not necessarily used inside VALID. And second, because the previous control doesn't have to be a GET but any controls.

This, obviously, is for the VALID clause of your example, in any other case, with HasFocus () is enough, as in my first example.

[Enrico Maria Giordano]

No, it is not. Try this sample. Neither of the two functions will work:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVr1 := SPACE( 30 )
    LOCAL cVr2 := SPACE( 30 )

    DEFINE DIALOG oDlg

    @ 1, 1 SAY "Test 1:" GET cVr1 VALID !EMPTY( GETACTIVE( oDlg ):VarGet() )
    @ 3, 1 SAY "Test 2:" GET cVr2

    ACTIVATE DIALOG oDlg;
             CENTER

    RETURN NIL


FUNCTION GETACTIVE( oDlg )

    LOCAL i

    FOR i = 1 TO LEN( oDlg:aControls )
        IF oDlg:aControls[ i ]:HasFocus()
            RETURN oDlg:aControls[ i - IF( i = 1, 0, 1 ) ]
        ENDIF
    NEXT

    RETURN NIL

Your example works fine.
What is it that I don't understand about your problem?

[Enrico Maria Giordano]

No, it doesn't work. You can move the focus from the first GET even if it is empty. Please note the VALID clause.

[cnavarro]

No, it doesn't work. You can move the focus from the first GET even if it is empty. Please note the VALID clause.

Enrico, I know this, and your sample run OK
Valid clause not allow move to second GET if GetVar() is empty

If you use xHarbour, you may have to use (GetActive (oDlg): oGet: VarGet ()) in case of GETs controls

Ciao Enrico,

try this

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()
        LOCAL oDlg
        LOCAL cVr1 := "FIRST" + SPACE( 15 )
        LOCAL cVr2 := "SECOND" + SPACE( 14 )
       
        SET KEY VK_F2 TO MYGET()
       
        DEFINE DIALOG oDlg TITLE "TEST"
       
        // @ 1, 1 GET cVr1 VALID !EMPTY( MYGETACTIVE():GetText() )  // !EMPTY( cVr1 )
        @ 1, 1 GET cVr1
        @ 3, 1 GET cVr2
       
        ACTIVATE DIALOG oDlg CENTER
RETURN NIL

STATIC FUNCTION MYGETACTIVE()
        LOCAL   oGet
       
        oGet := oWndFromhWnd( GetFocus() )
        IF oGet <> NIL
                IF oGet:ClassName() <> "TGET"
                        oGet := NIL
                ENDIF                
        ENDIF
RETURN oGet

STATIC FUNCTION MYGET()
        LOCAL   cBuf, oGet

        oGet := MYGETACTIVE()
        IF oGet <> NIL
            cBuf := oGet:GetText()
            MsgStop( cBuf )
        ENDIF
RETURN NIL

The problem is that when you use the function on valid the focus is already on the next field

Yes, yes, run OK, loo

You are not trying my last code. Try it, please. It is not working.
