I used to think that Thread.yield() did the trick, and it did in one
working example I had.
But then I used the exact same code in a piece of production code, and
it *didn't* work - mouse movement (ie, a Gtk event) required. Grr.
I recalled a comment someone made on IRC, and in a flash of inspiration,
speculated that if a GtkTimer was running, maybe it awakening would
cause an event which would get the main loop to fire.
This seems to work.
Code snippet:
Timer _ticker = null
int INTERVAL = 50;
...
_ticker = new Timer(INTERVAL, new Fireable() {
private long last;
public boolean fire() {
long now = System.currentTimeMillis();
System.err.println("Timer fired. Elapsed " + (now - last) + ", compared to interval "+INTERVAL);
last = now;
return true;
}
});
_ticker.start();
I know others have discussed the fundamental bug lurking down in the way
that CustomEvents is hooked into the main loop, but I don't off hand
know what that diagnosis is.
