Two ways. This works as long as both coordinates are positive:
lParam = (y << 16) | x
The more robust way is like this:
lParam = struct.unpack( 'L', struct.unpack( 'hh', x, y ) )[0]
However, it would be much better to talk to the tab control directly.
Are you doing this from inside the owning wx application? If so, you
should be able to get the tab control object and call the methods
directly. Even if you can only get the handle, you can use TCM_SETCURSEL.
