mouse position inside canvas

Hi !
Is there a method to have the mouse position inside a canvas if you not move the mouse or interact with it. (the mouse pointer is just on the canvas) ?
Thanks !

I'm at the work at the moment, but if I remember a canvas should emitt (if setted with EVENT_MOUSEMOVE) an event, and then you can read the result with EventX() EventY()

i'm ok with this, it's maybe a stupid question. But do you must store the mouse coord in you own variables (for example mx = eventx() and my=eventy()). Because if the mouse not move, not event is generated for the mouse so you can't check eventx() or eventy() !?!

in fact to move an object on the screen i need to determine deltax and deltay, (how many pixels mouse moved from last position)

yes, store them. I typically use ex and ey.

How to determine dx and dy ? (how many pixels mouse moved from last position) Where reinit dx=0,dy=0 when the mouse doesn't move ? Thanks to help me !

Thanks for your help. Finaly i have coded this. It's ok for my game editor.
