/**
|
* Simple plugin for using an Ext.tip.Tip with a slider to show the slider value. In general this class is not created
|
* directly, instead pass the {@link Ext.slider.Multi#useTips} and {@link Ext.slider.Multi#tipText} configuration
|
* options to the slider directly.
|
*
|
* @example
|
* Ext.create('Ext.slider.Single', {
|
* width: 214,
|
* minValue: 0,
|
* maxValue: 100,
|
* useTips: true,
|
* renderTo: Ext.getBody()
|
* });
|
*
|
* Optionally provide your own tip text by passing tipText:
|
*
|
* @example
|
* Ext.create('Ext.slider.Single', {
|
* width: 214,
|
* minValue: 0,
|
* maxValue: 100,
|
* useTips: true,
|
* tipText: function(thumb){
|
* return Ext.String.format('**{0}% complete**', thumb.value);
|
* },
|
* renderTo: Ext.getBody()
|
* });
