My Canvas like this:
public class somec extends Canvas implements Runnable{
.....
public void showNotify(){
running = true;
new Thread(this).start();
}
......
public void run(){
while(running){
....
repaint();
callSerially(this) //Warning here,"this" is not Runnable?!!
.......
}
}
public void paint(Graphics g){
.....
}
}
}
What is the problem here? How can I fix it ?

As stated in "J2ME in a Nutshell" - "The code to be executed in the event thread should be implimented in the run() method of the Runnable passed to the callSerially() method."
What that says to me is if your "this" is not runnable nothing will be executed
