Re: [platform-swt-dev] popup menu

[Frédéric Dreier <lists@xxxxxxxxx>]

Hi Steve,

I do not use key listener (or I don't know that I do). I have based my
menu on an example of the Book "SWT/JFace in action" using the
MenuManager. I use such code with Tree without getting this effect. Here is an example :


import org.eclipse.jface.action.Action;
import org.eclipse.jface.action.IMenuListener;
import org.eclipse.jface.action.IMenuManager;
import org.eclipse.jface.action.MenuManager;
import org.eclipse.jface.window.ApplicationWindow;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.MouseEvent;
import org.eclipse.swt.events.MouseListener;
import org.eclipse.swt.events.PaintEvent;
import org.eclipse.swt.events.PaintListener;
import org.eclipse.swt.graphics.GC;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Canvas;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Menu;

/**
 * @since XXX
 */
public class MyCanevas extends Canvas implements PaintListener,
MouseListener {
    MenuManager manager;

    static int counter= 0;

    public MyCanevas (final Composite parent, int style) {
        super(parent, style);
        addPaintListener(this);
        setBounds(0, 0, 100, 100);
        addMouseListener(this);
    }

    public void paintControl (PaintEvent arg0) {
        GC gc= arg0.gc;
       
gc.setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_BLUE));
       
gc.setForeground(Display.getCurrent().getSystemColor(SWT.COLOR_BLUE));
        gc.fillRectangle(getBounds());
       
gc.setForeground(Display.getCurrent().getSystemColor(SWT.COLOR_RED));
       
gc.setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_RED));
        gc.fillRectangle(35, 40, 30, 20);
        //       
        manager= new MenuManager("#PopupMenu");
        manager.setRemoveAllWhenShown(false);
        manager.addMenuListener(new IMenuListener() {
            public void menuAboutToShow (IMenuManager manager) {
                System.out.println("about to show...");
                manager.add(new DummyAction("[" + counter + "]"));
                counter++;
                System.out.println(">>> " + manager.getItems().length);
            }
        });
    }

    public void mouseDoubleClick (MouseEvent arg0) {
    }

    public void mouseDown (MouseEvent arg0) {
        System.out.println("mouse down");
        setMenu(manager.createContextMenu(this));

    }

    public void mouseUp (MouseEvent arg0) {
    }

    public static class DummyAction extends Action {
        public DummyAction (String text) {
            super(text);
        }
    }

    public static void main (String[] args) {
        Win wwin= new Win();
        wwin.setBlockOnOpen(true);
        wwin.open();
        Display.getCurrent().dispose();
        System.exit(0);
    }

    public static class Win extends ApplicationWindow {
        public Win () {
            super(null);
        }

        protected Control createContents (Composite parent) {
            new Container(parent);
            parent.setLocation(100, 100);
            return parent;
        }
    }

    public static class Container extends Composite {
        public Container (Composite parent) {
            super(parent, SWT.NONE);
            setLayout(new FillLayout());
            MyCanevas c= new MyCanevas(this, SWT.BORDER | SWT.V_SCROLL |
SWT.H_SCROLL
                | SWT.NO_BACKGROUND);
            c.setBounds(0, 0, 100, 100);
            setBounds(0, 0, 100, 100);

            pack();
        }
    }
}
