CWindow::ModifyStyle
Modifies the window styles of the CWindow object.
BOOL ModifyStyle(
DWORD dwRemove,
DWORD dwAdd,
UINT nFlags = 0
) throw();
Parameters
dwRemove
[in] Specifies the window styles to be removed during style modification.dwAdd
[in] Specifies the window styles to be added during style modification.nFlags
[in] Window-positioning flags. For a list of possible values, see the SetWindowPos function in the Windows SDK.
Return Value
TRUE if the window styles are modified; otherwise, FALSE.
Remarks
Styles to be added or removed can be combined by using the bitwise OR ( | ) operator. See the CreateWindow function in the Windows SDKfor information about the available window styles.
If nFlags is nonzero, ModifyStyle calls the Win32 function SetWindowPos, and redraws the window by combining nFlags with the following four 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, call ModifyStyleEx.
Example
//The following example attaches an HWND to the CWindow object and
//calls CWindow::ModifyStyle() to add and remove the window styles
CWindow myWindow;
myWindow.Attach(hWnd);
//The following line removes the WS_CLIPCHILDREN style from the
//window and adds the WS_CAPTION style to the window
myWindow.ModifyStyle(WS_CLIPCHILDREN, WS_CAPTION);
