WebRenderer JMenus

 

 

 

 Using JMenus with WebRenderer  - click here to download complete JMenu example code

 

Java JMenus are particularly useful in creating default context menus for right-click activation.

We have constructed a small example application demonstrating the use of JMenus and WebRenderer. When the menu items are clicked a message will be output to the command line from each menu item.

The core pieces of the code are as follows:

 

             IBrowserCanvas browser = BrowserFactory.spawnMozilla();
            /*
             * Disabling the default context menu right-click menu)
            */
            browser.enableDefaultContextMenu(false);

           JPopupMenu menu = new JPopupMenu("Context Menu");
           JMenuItem menuItem1 = new JMenuItem("Menu Item 1");
           JMenuItem menuItem2 = new JMenuItem("Menu Item 2");
           JMenuItem menuItem3 = new JMenuItem("Menu Item 3");
 
           menu.add(menuItem1);
           menu.add(menuItem2);
           menu.add(menuItem3);
 
           /*
            * Making the menu heavyweight - this prevents the menu going behind
            * the canvas. This is a bug with Swing menus,other Swing components do
            * not have this issue.
           */
           menu.setLightWeightPopupEnabled(false);
 
           //Nesting a MouseListener for the WebRenderer browser
           browser.addMouseListener(new MouseAdapter() {
                       public void onMouseDown(MouseEvent e) {
                                //Check if it is a right click
                                if (e.getModifiers() == 4) {
                                        //If it is a right click then show the menu
                                        int x = e.getX();
                                        int y = e.getY();
                                        menu.show(browser.getCanvas(), x, y);
                                        menu.repaint();
                                } else {
                                        menu.setVisible(false);
                                }
                        }
                });

Core code
 
Making the PopupMenu a heavyweight component is essential to ensure that the component shows above WebRenderer. setLightWeightPopupEnabled(false) sets the popup menu to heavyweight and has the correct Z-Order.
