Call this member function to modify a window's style.
UINT nFlags = 0
Specifies window styles to be removed during style modification.
Specifies window styles to be added during style modification.
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.
Nonzero if style was successfully modified; otherwise, 0.
Styles to be added or removed can be combined by using the bitwise OR (|) operator. See the topics
Window Styles and CreateWindow in the Windows SDK for information about the available window styles.
nFlags is nonzero, ModifyStyle calls the Windows API function SetWindowPos 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
For some styles in certain controls (the
ES_READONLY style in the edit control, for example), ModifyStyle may not properly change the style because the control may need to perform special internal processing. In these cases, a corresponding message to change the style will be available ( EM_SETREADONLY in the example mentioned).
// This example adds the WS_CLIPCHILDREN style to the window.
// No Styles are removed from the window.
