Shell Events
<![CDATA[
Shells can generate a unique type of event: shell events (ShellEvent).
A shell event is generated when a shell is minimized, maximized, activated, deactivated, or closed.
To add a shell listener to a shell, use this method:
public void addShellListener(ShellListener listener)
To remove a shell listener from a shell, use this method:
public void removeShellListener(ShellListener listener)
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.ShellEvent;
import org.eclipse.swt.events.ShellListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class ShellEvents {
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display, SWT.SHELL_TRIM);
shell.setLayout(new FillLayout());
shell.addShellListener(new ShellListener() {
public void shellActivated(ShellEvent event) {
System.out.println("activate");
}
public void shellClosed(ShellEvent arg0) {
System.out.println("close");
}
public void shellDeactivated(ShellEvent arg0) {
}
public void shellDeiconified(ShellEvent arg0) {
}
public void shellIconified(ShellEvent arg0) {
}
});
shell.open();
// Set up the event loop.
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
// If no more entries in event queue
display.sleep();
}
}
display.dispose();
}
}
