Why does examine mouse:

+-+ Prevent the cursor from leaving the window
+-+ Hide the default cursor

Is there a way to stop both those effects?

Thanks,

Ori

Because ExamineMouse is for Games. If u do not use a screen use other commands. (Look Window Lib Help)

Correct see the manual this snipit from the help file:

Code: Select all

PureBasic provides a full access to mices plugged to the computer. It supports standard mouses upto 3 buttons. This library is optimized and use very low level functions especially for use with games. Don't use the commands of this library in a regular application, in this case carry out the mouse query with WindowMouseX(), WindowMouseY() and EventType(). Under Windows the DirectX technology is used.

Well, with a windowed screen, the cursor just refuses the leave the screen, so i need to be able to move the cursor OUT of the screen and still have the screen functioning.

If you need access to the whole desktop when you're running a windowed screen application or game, you can't do InitMouse() and ExamineMouse() and you can't use the commands in the Mouse library. PureBasic or API substitutes exist for all these commands and you'll need to use those:

MouseX(), MouseY(): WindowMouseX(), WindowMouseY()
MouseDeltaX(), MouseDeltaY(): compute these with code from earlier values
MouseLocate(): MapWindowPoints_(), SetCursorPos_()
MouseButton(): GetAsyncKeyState_(#VK_LBUTTON), GetAsyncKeyState_(#VK_RBUTTON)

Ah-ha, sweet. So it was acctualy my engine and not the functions screwing up on me.

I've re-written my engine to work with these functions instead, although i've found that WindowMouseX()/WindowMouseY() wont be reported unless the mouse has acctualy moved in the window.

I'm thinking of something that may fix this, any advice would be good.

Edit: No, it did not work.

Thanks, but i said i figured that out.

What i was saying is that i don't seem to get any response from WindowMouseX/WindowMouseY unless the mouse has done an action (leftclick/move)

Posted: **Fri Aug 25, 2006 8:06 am**

In the code I posted, the mouse position is being reported and displayed in each loop. If WindowMouseX() or Y() were not testing correctly, it would display 0,0 right away. As the coordinates always display correct, it is working. If it isn't working for you, perhaps you could post some code.

Thanks, but i said i figured that out.

Didn't mean to offend - just might as well post it all as post cut-out pieces of a demo.

Hmm, interesting. I just had a look at your example with the debug and it seems to do what i was hoping mine would do... I'll keep looking through mine, will edit when if something comes up.

Edit:

...WindowWaitEvent()...*Rolls Eyes* - EVIL!!

Argh, sorry for wasting your time or offending you(if i did) netmaestro.

Thanks alot for the help, i hope i can pay you back one day.
