void com.google.scrollview.ui.SVPopupMenu.actionPerformed

(

ActionEvent

e

)

[inline]

A click on one of the items in our menubar has occured. Forward it to the item itself to let it decide what happens.

Definition at line 129 of file SVPopupMenu.java.

                                             {

    // Get the corresponding menuitem
    SVAbstractMenuItem svm = items.get(e.getActionCommand());

   svm.performAction(svWindow, SVEventType.SVET_POPUP);
  }

void com.google.scrollview.ui.SVPopupMenu.add	(	String	parent,
		String	name,
		int	id
	)		[inline]

Add a new entry to the menubar. For these items, the server will poll the client to ask what to do.

Parameters:

parent	The menu we add our new entry to (should have been defined before). If the parent is "", we will add the entry to the root (top-level)
name	The caption of the new entry.
id	The Id of the new entry. If it is -1, the entry will be treated as a menu.

                                                      {
    // A duplicate entry - we just throw it away, since its already in.
    if (items.get(name) != null) { return; }
    // A new submenu at the top-level
    if (parent.equals("")) {
      JMenu jli = new JMenu(name);
      SVAbstractMenuItem mli = new SVSubMenuItem(name, jli);
      items.put(name, mli);
      root.add(jli);
    }
    // A new sub-submenu
    else if (id == -1) {
      SVAbstractMenuItem jmi = items.get(parent);
      JMenu jli = new JMenu(name);
      SVAbstractMenuItem mli = new SVSubMenuItem(name, jli);
      items.put(name, mli);
      jmi.add(jli);
    }
    // A new child entry. Add to appropriate parent.
    else {
      SVAbstractMenuItem jmi = items.get(parent);
      if (jmi == null) {
        System.out.println("ERROR: Unknown parent " + parent);
        System.exit(1);
      }
      SVAbstractMenuItem mli = new SVEmptyMenuItem(id, name);
      mli.mi.addActionListener(this);
      items.put(name, mli);
      jmi.add(mli);
    }
  }

void com.google.scrollview.ui.SVPopupMenu.add	(	String	parent,
		String	name,
		int	id,
		String	value,
		String	desc
	)		[inline]

Add a new entry to the menubar. In this case, we also know its value and possibly even have a description. For these items, the server will not poll the client to ask what to do, but just show an input dialog and send a message with the new value.

Parameters:

parent	The menu we add our new entry to (should have been defined before). If the parent is "", we will add the entry to the root (top-level)
name	The caption of the new entry.
id	The Id of the new entry. If it is -1, the entry will be treated as a menu.
value	The value of the new entry.
desc	The description of the new entry.

    SVAbstractMenuItem jmi = items.get(parent);
    SVMenuItem mli = new SVMenuItem(id, name, value, desc);
    mli.mi.addActionListener(this);
    items.put(name, mli);
    if (jmi == null) { // add to root
      root.add(mli.mi);
    } else { // add to parent
      jmi.add(mli);
    }
  }

		int	x,
		int	y
	)		[inline]

Gets called by the SVEventHandler of the window to actually show the content of the popup menu.

Definition at line 141 of file SVPopupMenu.java.
