Hi Lucia,
Could you share a small minimized demo (ideally a live one) of what
you're doing ? That way, it would be easier to help.
Regards,
Alexandre

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
