Member Function Documentation

actionPerformed()

void com.google.scrollview.ui.SVPopupMenu.actionPerformed ( ActionEvent  e )

inline

A click on one of the items in our menubar has occurred. 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);
  }

add() [1/2]

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);
    }
  }

add() [2/2]

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);
    }
  }

show()

void com.google.scrollview.ui.SVPopupMenu.show ( Component  Invoker, 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.
