Hi Gordon,
Thank you for your help.
I modified following codes in order to make it work:
Fusion.Layers.Group = OpenLayers.Class(Fusion.Lib.EventMgr, {
...
show: function (noDraw) {
if (this.visible) {
return;
}
this.oMap.showGroup(this, noDraw ? true : false);
this.set('visible', true);
if (this.legend && this.legend.treeItem) {
this.legend.treeItem.check(true);
}
},
hide: function (noDraw) {
if (!this.visible) {
return;
}
this.oMap.hideGroup(this, noDraw ? true : false);
this.set('visible', false);
if (this.legend && this.legend.treeItem) {
this.legend.treeItem.check(false);
}
},
...
Fusion.Layers.Layer = OpenLayers.Class(Fusion.Lib.EventMgr, {...
show: function (noDraw) {
console.log('showLY: function (noDraw) ');
if (this.visible) {
return;
}
this.set('visible', true);
this.oMap.showLayer(this, noDraw ? true : false);
if (this.legend && this.legend.treeItem) {
this.legend.treeItem.check(true);
}
},
hide: function (noDraw) {
console.log('hideLY: function (noDraw) ');
if (!this.visible) {
return;
}
this.set('visible', false);
this.oMap.hideLayer(this, noDraw ? true : false);
if (this.legend && this.legend.treeItem) {
this.legend.treeItem.check(false);
}
},
...
initialize: function (legend, widgetTag) {...
layerPropertyChanged: function (eventID, layer) {
console.log('layerPropertyChanged');
if (typeof layer.legend.treeItem != 'undefined') {
layer.legend.treeItem.check(layer.isVisible());
}
},
...
