iconCls in ActionColumn not working

[serverfreak1982]

Hi again,

I want to use a CSS class to display icons in my ActionColumn but they won't show up.

What's the matter?

{
  xtype: 'actioncolumn',
  header: 'Aktion',
  menuDisabled: true,
  width: 25,
  items: [
  {
   iconCls: 'email_edit',
   tooltip: 'Mailbox bearbeiten',
   handler: function(grid, rowIndex, colIndex) {

    }
},

.email_edit{background-image:url(images/icons/email_edit.png); background-repeat: no-repeat;}

Already found an answer in the forum:

ActionColumn doesn't define a standard icon size, so you also need:

.x-action-col-cell img { height: 16px; width: 16px; }

(assuming your images are 16x16px)
