View Full Version : access variable from a function

7 Sep 2015, 6:48 AM
This is probably a silly question but I can not figure the answer.
Let's say I am defining a column for a grid in initComponent function

this.columns = [{
text: 'Name',
customVariable: "Something"
listeners: {
'focus' : function(comp, evObj, opts){
//access custom variable here

Can do I have access to customVariable from inside the listener's function?
comp.customVariable does not work and this.customVariable is refering to panel's scope.

Seems like the customVariable is defined on the column config. So, comp.columns[0].customVariable should work. Although, I am curious, how exactly is the 'focus' on the column getting fired? Also, why exactly would you need to access a varialble in such a way?

I needed to define a Ext.tip.ToolTip as a column variable in order to manually show when cell was on focus.
