MOUSE_MOVE Event on PlayBook

Hi guys,

 

I know this has been mentioned before in the forum but I want to make sure MOUSE_MOVE event is fully supported by the PlayBook.

 

I am simulating a "custom" dragging behavior using this sort of mouseEvent and I would like to know if anyone has implemented this. I see in simulator it works fine.

 

Thanks,

Re: MOUSE_MOVE Event on PlayBook

Sure it's supported, why not?  I don't recall any threads saying it might not be.

 

The thing is, MOUSE_MOVE events are generated at a high rate.  In the simulator, that's at least 100Hz... way way more than you need if you're merely doing dragging.

 

In such a case, you're likely better off (if the standard startDrag() stuff isn't okay for you) to set/clear a flag in MOUSE_DOWN/MOUSE_UP, and in an ENTER_FRAME handler (which runs at your frameRate) you handle the dragging stuff if the flag is set.

 

(Also best to add/remove that enterFrame handler when not dragging, if you don't have another purpose for it.)
