[Users] Transparencyslider on rightclick

[Dan Ramage]

Here: http://rcoos.org/carolinasrcoosrev2/secoora_interactive_tst.html is my
testing site.

The main javascript is here:
http://rcoos.org/carolinasrcoosrev2/lib/secoora_interactive_tst.js, but most
of the code dealing with the tree is here:

http://rcoos.org/carolinasrcoosrev2/lib/olMap1.0.js

 

 The slider is here:
http://rcoos.org/carolinasrcoosrev2/lib/GeoExt-1.0/lib/GeoExt/widgets/tree/L
ayerOpacitySliderPlugin.js

The mixin to make it work is here:
http://rcoos.org/carolinasrcoosrev2/lib/GeoExt-1.0/lib/GeoExt/widgets/tree/T
reeNodeUIEventMixinExtended.js

For my mixin, I basically just copied the base one, I couldn't seem to get
the Ext.extend() working and didn't want to spend a lot of time on that just
yet.

 

When I create my layers I have a couple of hash tags I add in the options
parameter to specify whether I want the slider or not.

In the olMap1.0.js, at the very top is my GeoExt.tree.layerLoaderExtended
where I make sure only the tree nodes that have the option set to have a
slider get them. If I didn't do this, every layer in that layercontainer
node would have a slider.

 

In the LayerOpacitySliderPlugin.js, the onRenderNode is where most of the
work gets done. I used the RadioButtonPlugin.js as a guide on how to go
about doing this. I used the Ext.Slider() widget.

 

This was a big learning experience for me, I am still not anywhere as
knowledgeable about javascript as I would like.

Sure, do you have example-code or a description

I implement a slider in the layer tree. Not sure if that is helpful or not.

Hi

Nice, then we have the min/max scale. 

Is there anyone who implemented the transparencyslider on rightclick as
vell?

Looking forward to get rid of MapFish in the client.
