SWT Event Handling with Displays : Display « SWT « Java Tutorial





The readAndDispatch reads events from the operating system's event queue and then dispatches them appropriately.

import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class SWTEventHandlingDisplay {

  public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setText("Hello, world!");
    shell.open();

    while(! shell.isDisposed()) { // Event loop.
        if(! display.readAndDispatch())
          display.sleep();
    }
    display.dispose();
  }

}
