Notes On Version 3 Api

Maps V3 api needs outside help due to limited resources currently on other projects at the moment. I am suggesting automating the javascript implementation build process to help us not fall behind on future javascript api version. (Automating is the GWT APIs team idea, Thanks Eric)

• Automate Issue - Lets get the api build process automated so we don't fall behind again!
• Request V3 Issue - Issue for version 3 api.
• V3 Contribution Discussion - V3 contribution, vinray has made a v3 api, but JSIO objects have to be stripped

Demo GWT Maps

The goal is to render or a map with GWT.

• Demo - Simple Maps Demo
• Source - find the source here
• c.Gawkat.com - I use gwt maps api here for my panoramic virtual tours.

Custom Map Controls

Want to add your own control to the map.

    ControlPosition controlPosition = new ControlPosition(ControlAnchor.TOP_LEFT, 100, 0);
    Control handControl = new Control.CustomControl(controlPosition) {
      public boolean isSelectable() {
        return true;
      }
      protected Widget initialize(MapWidget map) {
        Image mhand = new Image(UI_IMAGES.map_hand());
        mhand.addClickHandler(new ClickHandler() {
          public void onClick(ClickEvent event) {
            // do something
          }
        });
        return mhand;
      }
    };
    map.addControl(handControl);

Method example

private void drawMapAddItems() {
    final Image mhand = new Image(UI_IMAGES.map_hand());
    final Image mhandsel = new Image(UI_IMAGES.map_hand_sel());
    
    final Image mpush = new Image(UI_IMAGES.map_add_pushpin());
    final Image mpushsel = new Image(UI_IMAGES.map_add_pushpin_sel());
    
    
    ControlPosition controlPosition = new ControlPosition(ControlAnchor.TOP_LEFT, 100, 0);
    Control handControl = new Control.CustomControl(controlPosition) {
      public boolean isSelectable() {
        return true;
      }
      public Widget initialize(MapWidget map) {  
        return mhand;
      }
    };
    map.addControl(handControl);
    
    ControlPosition controlPosition2 = new ControlPosition(ControlAnchor.TOP_LEFT, 100, 0);
    Control handControl2 = new Control.CustomControl(controlPosition2) {
      public boolean isSelectable() {
        return true;
      }
      public Widget initialize(MapWidget map) {  
        return mhandsel;
      }
    };
    map.addControl(handControl2);
    
    mhand.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        mhand.setVisible(false);
        mhandsel.setVisible(true);
      }
    });
    
    mhandsel.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        mhand.setVisible(true);
        mhandsel.setVisible(false);
      }
    });
    
    mhandsel.setVisible(true);
    mhand.setVisible(false);
  }
