CWnd::ModifyStyle

  • Article

BOOL ModifyStyle( DWORD dwRemove**, DWORD** dwAdd**, UINT** nFlags = 0 );

Return Value

Nonzero if style was successfully modified; otherwise, 0.

Parameters

dwRemove

Specifies window styles to be removed during style modification.

dwAdd

Specifies window styles to be added during style modification.

nFlags

Flags to be passed to SetWindowPos, or zero if SetWindowPos should not be called. The default is zero. See the Remarks section for a list of preset flags.

Remarks

Call this member function to modify a window’s style. Styles to be added or removed can be combined by using the bitwise OR (|) operator. See the topics and in the Win32 SDK Programmer’s Reference for information about the available window styles.

If nFlags is nonzero, ModifyStyle calls the Windows API function and redraws the window by combining nFlags with the following four preset flags: 

  • SWP_NOSIZE   Retains the current size.

  • SWP_NOMOVE   Retains the current position.

  • SWP_NOZORDER   Retains the current Z order.

  • SWP_NOACTIVATE   Does not activate the window.

To modify a window’s extended styles, see ModifyStyleEx.

Example

// This example adds the WS_CLIPCHILDREN style to the window.
// No Styles are removed from the window.

void CMyView::OnInitialUpdate()
{
   CView::OnInitialUpdate();
   ModifyStyle(0, WS_CLIPCHILDREN);
}
