              xtype: 'hr_layerlegendpanel',
              defaults: {
                      useScaleParameter : false,
                      baseParams: {
                          // Override default image/gif in WMS GetLegendGraphic
                              FORMAT: 'image/png'
                      }
              },
              hropts: {
                      // Preload Legends on initial startup
                      // Will fire WMS GetLegendGraphic's for WMS Legends
                      // Otherwise Legends will be loaded only when Layer
                      // becomes visible. Default: false
                      prefetchLegends: false
              }
      }
