I know this is a pretty old thread, but i just started with Yii and love it so far.
I stumbled over this nice little extension. I’m not that experienced in OOP-PHP, so i don’t want to mess around in the class-file.
In my GridView i don’t use any icon-images for the CButtonColumn. Instead i use Fontawesom. (for example: [font=“Courier New”]‘label’=>’<i class=“fa fa-search”></i>’[/font] shows a search icon)
Is there any way to use Fontawesome instead of an image for the filter button? Even if i try [font=“Courier New”]‘imageUrl’=>false[/font], the nasty little delete.png is shown, instead of the label (though the readme says: “[font=“Courier New”]imageUrl: image URL of the button. If not set or false, a text link is used Default is: $this->grid->baseScriptUrl.’/delete.png’[/font]”.
There is only a textlink, if i set an fantasy name as imageUrl.
The original CButtons can handle HTML in the label, so i can use fontawesome. At the moment i do a hack using jquery to replace the img-tag. It works, but i’d like to do it right 
Any ideas?
