Drawing a virtual mouse cursor
Hello, my question is related to a previous one I asked recently. Although I've made progress with restricting the mouse cursor to a certain area, there are artifacts that bug me and I wish to fix them.
- When the cursor is leaving the window I get a resize icon shown that I wish to avoid. Unfortunately, the resize cursor is not managed by Qt but by the window manager instead.
- There is significant flicker at the edges, especially if the mouse movement is fast. I attribute this to the way events are handled - after the cursor changes position, Qt is notified, it creates and dispatches the mouse event, in which I'm setting the cursor position anew, to the correct coordinates - if I'm wrong please correct me. This means that I'm actually intercepting the event after the OS has handled the cursor movement and this leads to flicker.
@Chris-Kawa has suggested that I implement a virtual cursor and intercept and dispatch the mouse events by myself. This if fine with me. The question is how to draw the virtual cursor. Is it supposed to be a widget that I'll be moving around, a pix/bitmap that I should draw directly on the screen? One other thing I was wondering about is, whether I could use the system cursor (image) in some way (I don't intend to change its appearance). Any suggestion on how to go about drawing the cursor is greatly appreciated.
