Creates a hidden window with supplied window proc registering the class for
|
||
|
|
it if necessary (i.e. the first time only). Caller is responsible for
|
||
|
|
destroying the window and unregistering the class (note that this must be
|
||
|
|
done because wxWidgets may be used as a DLL and so may be loaded/unloaded
|
||
|
|
multiple times into/from the same process so we can't rely on automatic
|
||
|
|
Windows class unregistration).
|
||
|
|
|
||
|
|
pclassname is a pointer to a caller stored classname, which must initially be
|
||
|
|
NULL. classname is the desired wndclass classname. If function successfully
|
||
|
|
registers the class, pclassname will be set to classname.
