qgraphicsview cursor setting logic

[wysota]

With singleShot timer, I can get the delay but the single/slot does not allow any arguments, eg new cursorMask . . . but I can probably work around that.
With invokeMethod, I can call the needed method with the proper argument, but I do not see a way to specify a delay? Am I missing something? Or are you saying to just use a 20 ms sleep?

No, no sleep(). You can store the "argument" in some member variable and then fetch it from there when the timer fires.

Right, no sleep . . . was just thinking how to use the invokeMethod.

I implemented the singleShot timer, and while it works with my linux laptop, it does not seem to work on my windows test machine. The cursor changes, but once I move the mouse it reverts to the previous cursor again.

I did find QTBUG-3732 and QTBUG-4190 in the Qt bug reports, which both seem exactly related to what I am seeing. However, they are both closed (2009/2010). What is the best procedure to re-open these bugs, because it looks like an obvious logic problem with the cursor and graphicsview. My suggestion would be to get rid of the internal originalCursor and use the cursor of the GraphicsView, since that it not really used anywhere, for the cursor of the viewport. I guess in the meantime I need to abort what I am trying to accomplish or try to "fix" graphicsview with my oen code.

Also, when I was working in windows, I noticed that the cursors are really unusable with a view that is mostly black (especially CrossCursor) . . . the cursor just "disappears". Do I need to use a custom cursor to get the same feel as with linux and X11?
