How to hide the entire Ext.selection.CheckboxModel in ExtJS grid

Question

I need to hide the entire column of the check box (Ext.selection.CheckboxModel). I found out to get the columns of the grid to hide, but the columns does not give the checkbox column.

Answer 1

grid.headerCt.items.getAt(0).hide()

Answer 2

This worked for me in 4.2.2. I used a combination of the other answer by Saki and a little traversing through the DOM because the "getAt0).hide()" solution did not work for me either:

grid.headerCt.items.items[0].hidden = true;
