3. GXM Buttons

In the previous section we finished with an application consisting of a Map and a LayerList managed inside of a TabPanel.

Next we want to enhance the map application by adding additional controls to the Map. These controls shall be managed by Button which we want to attach to a new Toolbar located at the bottom of the Map.

We’ll accomplish this in three steps

• 3.1. Add zooming-controls and appropriate buttons,
• 3.2. Add digitizing/redlining controls and buttons,
• 3.3. Add a geolocation button.
