CWindow::ResizeClient() Function for CWnd (or derived classes)

Posted by Christian Perger on January 26th, 2001
With this Function you can resize the window to the specified client area size of your CWnd or derived classes like the CWindow::ResizeClient() function.

Example

You have a dialog based application and the client rect of the dialog depends on the size of a bitmap.

Source Code

BOOL CYourWndOrDialog::ResizeClient (int nWidth, 
                                     int nHeight, 
                                     BOOL bRedraw)
{
 RECT rcWnd;
 GetClientRect (&rcWnd);

 if(nWidth != -1)
  rcWnd.right = nWidth;
 
 if(nHeight != -1)
  rcWnd.bottom = nHeight;

 if(!::AdjustWindowRectEx(&rcWnd, 
                          GetStyle(), 
                          (!(GetStyle() & WS_CHILD) 
 && GetMenu() != NULL)), GetExStyle()))
  return FALSE;

 UINT uFlags = SWP_NOZORDER | SWP_NOMOVE;

 if(!bRedraw)
  uFlags |= SWP_NOREDRAW;

 return SetWindowPos(NULL, 
                     0, 0, 
                     rcWnd.right - rcWnd.left, 
                     rcWnd.bottom - rcWnd.top, 
                     uFlags);
} // CYourWndOrDialog::ResizeClient
