mouseMoved to ignore QCursor.setPos()?

I'm calling QCursor.setPos() while the cursor is inside my widget. When I do, mouseMoveEvent is called, when I don't want it to be. In Java/Swing I can move the cursor without sending events. Can I do something similar so calls to QCursor.setPos() so don't send a mouseMoveEvent?

This seems to work for me:

myWidget->clearFocus();
QCursor::setPos(pos);
myWidget->setFocus();

I ended up just keeping track of the difference in between mouse movements, so if I get a mouse movement of 5 to the right, for example, I store the five and ignore the next event if it moves me 5 to the left (which means it's probably called by setPos). Not really elegant, but it appears to work reliably.

Looks like there is no way to setPos without trigger mouseMoveEvent, maybe you consider create a :

bool disableMoveProcess;

and make it as a flag for provent your logic running?

I use this method for calling QListWidgetItem::setSelected without make QListWidget::itemSelectionChanged trigger my code.
