Class QtRepaintThread

Implemented Interfaces:
Runnable
public class QtRepaintThread
extends Thread
This class does repainting of Component back-buffers. It is undesirable to do this directly from the paint callback in QtComponentPeer, because that is executed from the main thread. Thus, if a call is made at the same time which requires execution by the main thread, and this is sharing a lock with paint(), then a deadlock will occur, which must be avoided. In general, the main Qt thread should avoid calling into java code as far as possible.
