Subject: Allegro mouse pointer with windows
Precedence: bulk

Hi,


I want to devolop a windowing system using allegro. The mouse should have
diff. cusor shapes depending on the window it is over. Now I felt that it wd
be wise to divide the screen into and array of 4x4 or 8x8 blocks, with
each array element storing a pointer (or index) to an allegro mouse sprite.
Then, each window sets the relevant
parts of this array to point to whatever sprite it likes. The advantage is
that this is faster than sending a message/signal to a function with mouse
coords, and that switching the cursor shape. Also, less hassle. However,
this requires shawn to support it (or something similair) in his 3.0
version. Is this worth asking for? Is there a better method? 

Also, Shawn, if u r reading this, is it possible in allegro 3.0 to allow the
user to define a rectange within which the pointer should never be visible
(it should be invisible whenever it is inside the rect, and
visible/invisible outside). I had done this for text mode in 16-bit and
found it extremely helpful.

Bye,
