How many different setups of the mouse is there?

I have been playing around with my mouse code - the one I used to use made the mouse trapped inside the window even if I was in windowed mode, so that obviously needed a change.

So now - using code like this to set up the mouse:

  enable_hardware_cursor();

  set_mouse_sprite(somebitmap);

and gfx_capabilities returns no HW_CURSOR and no SYSTEM_CURSOR, but still I got a mousepointer that is visible "outside" of the window in windowed mode when moved to the edges. Is this expected?

I mean - the full bitmap that is used as a mouse pointer is visible over the desktop when moved to the right and bottom edges even if a normal allegro bitmap would be cut and limited to the window.

I am on my Debian Etch using Allegro 4.2.1 (the version meant for testing that were uploaded on the mailinglist or if it was the forum a while ago).

Anyway - The main question is - Am I just "lucky" being on an X system, and this isn't reproducible on other platforms - I think I saw something like that mentioned concerning DirectX Fullscreen at least.

Hi attach a screenshot; my mouse sprite doesn't go out of the window!

EDITED: Well I've just seen that pic and of course mouse doesn't appear jaja but I ensure you it doesn't go out..

Heh - Yeah - seems harder than one might think to get a screenshot of this... both Gnome-screenshot and Gimp seem to remove the Mouse before saving the image...

[Edit]

Self-made screenshot attached. -this is exactly what it looks like - but since there are troubles including the mouse in the screen-capture I made the effect by hand.

(the disk is the mouse pointer.)

When are you testing gfx_capabilities? The HW_CURSOR and SYSTEM_CURSOR flags are only set after you call show_mouse(). Anyway, if the cursor shows over the edge of the screen (as opposed to being clipped against the window edge), it is a hardware cursor.
Also check what the test program says about having or not having a hardware cursor.

X11 always supports hardware cursors in both windowed mode and fullscreen mode if the proper X11 extensions are available, but they interfere with get_mouse_mickeys(), which wants to trap the physical cursor in the centre of the window to get an infinate range of mouse movement. So they are disabled by default.
Actually, I think DirectX fullscreen is the only platform that doesn't do hardware cursors at all.

Ah - Yeah, its my confusion that has gotten into play once again

I thought that I should use the gfx_capabilities to make sure I could make use of a hardware cursor, when it actually represents if you are using it or not (by previously setting it using enable_hardware_cursor).

Anyway - Thanks Evert!

That's what one would normally expect, but unfortunately it can't reliably work that way: in Windows, for instance, you can only use hardware cursors under certain conditions (there are size restrictions) and you don't know if you can get a hardware cursor until you try.

You're welcome.
