Posted on August 18, 2014 at 07:41Hi,
I have a problem with touchscreen cursor:
When I move my finger on the touchscreen, although the cursor follows me, it remains its trace on the LCD. As if I'm drawing something, like in a Paint program.
My deduction is that the cursor movement does not invalidate area it has been, so emWin does not redraw that area. I added:
WM_InvalidateArea(&myrect);
to the codes, myrect being a rect which covers around where cursor has been. But still there would be traces left uncleaned if I move the cursor fast.
What am I doing wrong? Isn't cursor trace clean up an automatic function?
Thanks,
Ali
