Hello,everyone,I'm new here..and I'm new for easyui.
I have two questions:
How can I set the icon use my png file?
And How can I get all of the internal icon name,like 'icon-edit','icon-ok',etc.
Can I get the name list? thanks!

The icon CSS is defined in 'themes/icon.css' file. It looks like this:

Code:

.icon-add{
	background:url('icons/edit_add.png') no-repeat center center;
}
.icon-clear{
	background:url('icons/clear.png') no-repeat center center;
}
