owner draw...

I'm trying to make an owner drawed button, but no luck yet...

I've been following the msdn example, but it's weird and doesn't work:

Can someone give me a working example without using classes?




Thank you.

Code:

---

CreateWindow( "Button", "My Button", WS_CHILD|WS_VISIBLE, 10, 10, 60, 30, hwndParent, (HMENU)MY_BUTTON_ID, hInstance, NULL );

...
case WM_DRAWITEM: {
 
  DRAWITEMSTRUCT *dis = (DRAWITEMSTRUCT*)lParam;
  RECT rc;
  GetWindowRect( hwnd, &rc );
  rc.right-=rc.left
  rc.bottom-=rc.top;
  rc.top = rc.left = 0;
 
  HBRUSH red = CreateSolidBrush( RGB( 255,0,0 ) );
  HBRUSH green = CreateSolidBrush( RGB( 0,255,0 ) );
 
  if ( dis->itemAction&ODA_FOCUS && dis->itemStat&ODS_FOCUS ) {
     
      FillRect( dis->hDC, &rc, green );
     
  }else if ( dis->itemAction&ODA_FOCUS ) {
     
      FillRect( dis->hDC, &rc, red );
     
  }
 
 
  SetBkMode( dis->hDC, TRANSPARENT );
  int txtLen = GetWindowTextLength( hwnd );
  char buff[txtLen];
  GetWindowText( hwnd, buff, txtLen);
  DrawText( dis->hDC, buff, txtLen, &rc,  DT_CENTER|DT_VCENTER|DT_SINGLELINE );
  DeleteObject( red );
  DeleteObject( green );
 
  return TRUE;
}
...

That's a pretty lame example, if it even works... There are a few things that you would not do there, like use GetWindowRect() normally because it supplies a rect but I wasn't sure if it was client or screen so I didn't use it.. That is essentially all you need though.

I'm not sure if the dc is released for you either, the documentation didn't say. Probably best to do that as well.

can you please give me an example with bitmap buttons?

uhmm.... if you know anything about bitmaps, you can take that example and apply bitmaps to it, all you have to do is get a device context,etc. like a bitmap.

Well, to add a bitmap use BitBlt() ...

Say you've loaded your bitmap and it's called hBmp.

Code:

---

...
HDC tmpDC = CreateCompatibleDC( dc );
SelectObject( tmpDC, hBmp );
BitBlt( dc, x1, y1, cx, cy, tmpDC, 0,0, SRCCOPY );
...

x1 and y1 would be where you want the top left point of the bitmap to be, cx and cy are the width and height of the bitmap respectively ...

Here's an example of owner-drawn buttons using bitmaps.

Note: The bitmaps should be in the same directory as the program.

Edit: You may also notice that the buttons don't respond well to double-clicks. The solution is simple, just subclass the buttons and handle the WM_LBUTTONDBLCLK message by sending a WM_LBUTTONDOWN message.

got it, thanks
