Difference between mouse and keyboard

[MarcoBoschi]

Hi,
please compile this little sample program.

Code: Select all | Expand

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVar := SPACE(10)

    CGETFILE( "*.*", "Select a file" )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVar

    @ 2, 1 BUTTON "Button1"
    @ 3, 1 BUTTON "Button2"

    ACTIVATE DIALOG oDlg

    RETURN NIL

First time use keyboard to select file into CGETFILE dialog ( you can use mouse and press keyboard just one time)

When you return to dialog oDlg and you change focus into Button1 everything works fine.



Second time use only mouse (please do not touch keyboard)
When Button1 gets focus it does not appear in the right way


Any suggestions?
Marco

Marco,

If you press "Alt" then the dotted line will appear.

Somehow, Windows seems not to show it if only using the mouse.

[MarcoBoschi]

Antonio,
the solution is to simulate an "Alt" press?
Thanks

[Antonio Linares]

Marco,

The problem is that we can not simulate an "Alt" key

We are trying many different ways, but no success. We just need a simple "Alt" simulation there...

    oBtn:bGotFocus = { || oBtn:PostMsg( WM_SYSCOMMAND, SC_KEYMENU ) }
    
    @ 3, 1 BUTTON "Button2"

    ACTIVATE DIALOG oDlg CENTER

    RETURN NIL

Hi,

See if this works to you :

Code: Select all | Expand

#include "Fivewin.ch"

#define VK_LMENU  164
#define VK_A       65

FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVar := SPACE(10)

    CGETFILE( "*.*", "Select a file" )

    DEFINE DIALOG oDlg

    @ 1, 1 GET cVar

    @ 2, 1 BUTTON oBtn PROMPT "Button1"
    oBtn:bGotFocus = { || SetStateKey( VK_LMENU, .T. ), ;
                          SetStateKey( VK_A, .T. ), ;
                          SetStateKey( VK_LMENU, .F. ) }
   
    @ 3, 1 BUTTON "Button2"

    ACTIVATE DIALOG oDlg

RETURN NIL

#pragma begindump

#include <windows.h>
#include <hbapi.h>

HB_FUNC( SETSTATEKEY )
{
  if( hb_parl(2) )
      keybd_event( hb_parvnl(1), 0x45, KEYEVENTF_EXTENDEDKEY | 0, 0 );
  else
      keybd_event( hb_parvnl(1), 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
}

#pragma enddump

Rossine,

Very good!

many thanks!

When compiled, I got an error message Unresolved external '_hb_parvnl'. What lib am I missing?

[Antonio Linares]

Hua,

Please change hb_parvnl() with hb_parnl() calls

[hua]

Please change hb_parvnl() with hb_parnl() calls

It worked. Thanks.

Hello,
just now I read your answers.
Thanks a lot.
I've tried it but if I press return key in the field it does not work.
It works only if I press TAB button to exit get field.
Anyway, thanks a lot
