Hello
This is the class MyExposeListener:
Quote:
import org.gnu.gtk.event.ExposeEvent;
import org.gnu.gtk.event.ExposeListener;
import com.irex.mobipocket.reader.Utils;
import com.irex.sdk.DisplayUpdate;
public class MyExposeListener implements ExposeListener
{
public boolean exposeEvent(ExposeEvent arg0)
{
if(arg0.isOfType(ExposeEvent.Type.EXPOSE))
{
System.out.println("refresh");
DisplayUpdate displayupdate = DisplayUpdate.getInstance();
displayupdate.dispMainWinFullQ();
}
return true;
}
}
|
This class is invoked as an event by the constructor of class TextBuffer:
Quote:
|
w.addListener(new MyExposeListener());
|
The class TextBuffer runs and sometimes returns following errors and the program ends its execution:

|
These errors depend from the instruction:
Quote:
|
w.addListener(new MyExposeListener());
|
because without this instruction I have no errors during the execution.
How can solve this problem?
Thanks
