Hello GeoExt users,
after long searching for a solution I found the OpacitySliderPlugin, now
renamed to ContextMenuPlugin to integrate into the LayerTree.
I inserted the ContextMenuPlugin with a LayerOpacitySliderTip-Plugin in the
LayerTreeBuilder.js and now it does what I want:
Code snippet of LayerTreeBuilder.js:
initComponent: function(){
this.addEvents(this.CUSTOM_EVENTS);
this.plugins = this.plugins || [];
this.plugins.push({ptype: "gx_treenodecomponent"});
this.plugins.push(new GeoExt.ux.plugins.LayerTreeBuilderNodeAgent());
//Context menu with opacity slider, added by Lucia:
this.plugins.push(new GeoExt.tree.ContextMenuPlugin({
sliderOptions:{
aggressive: true,
plugins: new GeoExt.LayerOpacitySliderTip()
}
})
);
GeoExt.ux.tree.LayerTreeBuilder.superclass.initComponent.call(this);
if(!this.layerStore) {
this.layerStore = GeoExt.MapPanel.guess().layers;
}
this.layerStore.on({
"add": this.onLayerAdded,
"remove": this.onLayerRemoved,
scope: this
});
this.layerStore.treeBuilder = this;
},
Three remarks:
1. It's hard to find new developments. I'm searching always with key words like
"opacity slider" "layertree" and similar. In my opinion there is a lack of
finding the latest improvements. The code examples are not linked to these key
words, isn't it?
2.It would be nice for a boolean option of the LayerTreeBuilder to set
"ContextMenu: true/false", without manipulating the code of the
LayerTreeBuilder.js itself. Maybe also with SliderOptions for a possible
integrating of the very useful LayerOpacitySliderTip.
3. There is a Error executing the new code: "this.dom.style is null or not an
object" referring to ext-all.js.
Does anybody know how to fix it?
Thanks
Lucia

Betreff: [Users] OpacitySlider for each Layer in a LayerTree(LayerTreeBuilder)
Hi GeoExt users,
I have a second question:
Do anybody know how to combine LayerTreeBuilder with a OpacitySlider for each
visible layer in the tree?
I managed only either legend or OpacitySlider, but I want both!
Thank you
Lucia
