[Users] custom text for ZoomSliderTip

[Moen Endre]

Thanks Chris! That works. I extended the data object that was already in getText with 
  region: zoomSliderRegionLookup[thumb.value]

Cheers
Endre

Hi Endre,

at the moment there is no out-of-the-box solution for this neither in GeoExt 1.x nor in GeoExt 2.x. According to your sample code I guess that you use GeoExt 1.x ?

You can achieve this by defining a lookup object mapping e. g. the zoom level to a text:

var lookup = {
    0: "International" ,
    1: "National",
    // ...
}

and read the text defined by the zoom level and pass it via the 'getText' function of the slider's tip , like this (untested):

...

     plugins: new Ext.slider.Tip({
         getText: function(thumb){
             return String.format('{0}', lookup[thumb.value]);
         }
     })

...

Hope this helps as a kind of kickstart.

Cheers,
Chris

But the only variables that can be used is {scale}, {resolution} and {zoom}. How is the best way of adding these new text strings? E.g. I would like International to be associated with zoom level 0,1, and 2.
