<br>
Since making the actual HandMorph & real cursor do gridding seemed a bit of a heavyweight thing to impose on everything else, I’m attempting to do it by handling mousemove events within my painting canvas morph. It *almost* works but there is something very odd going on at far too frequent occasions.<br>
<br>
So far as I can currently tell the event handling code up in Morph & HandMorph is sometimes deciding that the mouse has left my morph and thus sends me a mouseleave event instead of a a move. Then as soon as the cursor moves, I get a new mouseenter and more moves until whatever it is upsets things again. There’s some unpleasantly complex code up at MouseOverHandler>processMouseOver: for example that appears to be in the middle of my problem - best I can tell is that ‘leftMorphs’ is somehow including my morph when the mouse is still right there in the middle of it.<br>
<br>
My basic scheme is to create a suitable ImageMorph on the mouseEnter, change its position with each mouseMove and then delete it on mouseLeave. I have implemented handlesMouseMove: to always return true, so I seem to get all the move events.<br>
<br>
Any idea about why I get the dud mouseLeave events? Has anyone else done a scaled-up-grid-cursor thingy?<br>
