| Code: |
int thread()
{
int i = 0;
while(!wants_to_quit) {
synchronized {
label.setLabel(std.string.toString(i));
}
writefln("i=?d", i);
++i;
std.c.time.sleep(1);
}
return 0;
}
|
This simple thread code makes the app window stop responding after some time. I can use it for a little while, while watching the label change, and soon it stops responding at all, it not even redraws on an expose. The thread continues to run, tough, as it continue to print on stdout. Then I have to ctrl-C on the console to stop it and close the stalled window.
Does (dyn)DUI plays nice with threads?
Am I doing something wrong?
Does the 'synchronized' use makes any sense?
Will my mp3 mplayer ever take off from ground? |

Threads are a known problem on DUI.
I'm not sure what's the problem.
Any help is welcome.

Ok, I found a way to workaround the problem:
| Code: | int thread() {
int i = 0;
while(running) {
new_label = std.string.toString(i);
++i;
std.c.time.sleep(1);
}
return 0;
}
void go() { // this is called instead of DUI.dui.go()
while(running) {
DUI.dui().processPendingEvents();
std.c.time.usleep(10000);
if(new_label != label.getLabel())
label.setLabel(new_label);
}
}
