Re: Capture arrowkeys

[James E Stover <stoverje@worldnet.att.net>]

Hi Jakob!

I am using the following technique to do what you want.

In your Form .h file, add the following line to your Private section:

    void __fastcall CMDialogKey(TWMKey &message);

Next, in your header file, at the following as a Message Map Handler to
your Form class:

BEGIN_MESSAGE_MAP
MESSAGE_HANDLER(CM_DIALOGKEY, TWMKey, CMDialogKey)
END_MESSAGE_MAP(TForm)


Then, in your Form .cpp file, add a function to handle CMDialogKey:

void __fastcall TYourForm::CMDialogKey(TWMKey &message)
{
   int myKey = message.CharCode;

   if(myKey == VK_RIGHT)
      SendMessage(hWnd, WM_HSCROLL, SB_PAGEDOWN, NULL);
   if(myKey == VK_LEFT)
      SendMessage(hWnd, WM_HSCROLL, SB_PAGEUP, NULL);
  }

where hWnd is the window handle of a control I am scrolling left and right
in this case.


Hope this helps you,
Jim Stover
