* value in a window's extra memory.
|
|
*
|
|
* The _hwnd_ parameter specifies the window. is the handle to a

* window that has extra memory. The _newval_ parameter contains the
|
|
* new attribute or extra memory value. If positive, the _offset_
|
|
* parameter is the byte-addressed location in the window's extra
|
|
* memory to set. If negative, _offset_ specifies the window
|
|
* attribute to set, and should be one of the following values:
|
|
*
|
|
* GWL_EXSTYLE The window's extended window style
|
|
*
|
|
* GWL_STYLE The window's window style.
|
|
*
|
|
* GWL_WNDPROC Pointer to the window's window procedure.
|
|
*
|
|
* GWL_HINSTANCE The window's pplication instance handle.
|
|
*
|
|
* GWL_ID The window's identifier.
|
|
*
|
|
* GWL_USERDATA The window's user-specified data.
|
|
*
|
|
* If the window is a dialog box, the _offset_ parameter can be one of
|
|
* the following values:
|
|
*
|
|
* DWL_DLGPROC The address of the window's dialog box procedure.
|
|
*
|
|
* DWL_MSGRESULT The return value of a message

* that the dialog box procedure processed.
|
|
*
|
|
* DWL_USER Application specific information.
|
|
*
|
|
* RETURNS
|
|
*
|
|
* If successful, returns the previous value located at _offset_. Otherwise,
|

* returns 0.
|
|
*
|
|
* NOTES
|
|
*
|
|
* Extra memory for a window class is specified by a nonzero cbWndExtra
|
|
* parameter of the WNDCLASS structure passed to RegisterClass() at the
|
|
* time of class creation.
|
|
*
|
|
* Using GWL_WNDPROC to set a new window procedure effectively creates
|
|
* a window subclass. Use CallWindowProc() in the new windows procedure
|
|
* to pass messages to the superclass's window procedure.
|
|
*
|
|
* The user data is reserved for use by the application which created
|
|
* the window.
|
|
*
|
|
* Do not use GWL_STYLE to change the window's WS_DISABLE style;
|
|
* instead, call the EnableWindow() function to change the window's
|
|
* disabled state.
|
|
*
|
|
* Do not use GWL_HWNDPARENT to reset the window's parent, use
|
|
* SetParent() instead.
|
|
*
|
|
* Win95:
|
|
* When offset is GWL_STYLE and the calling app's ver is 4.0,
|
|
* it sends WM_STYLECHANGING before changing the settings
|
|
* and WM_STYLECHANGED afterwards.
|
|
* App ver 4.0 can't use SetWindowLong to change WS_EX_TOPMOST.
|
|
*
|
|
* BUGS
|
|
*
|
|
* GWL_STYLE does not dispatch WM_STYLE... messages.
|
|
*
|
|
* CONFORMANCE
