Is there any way to change the icon of for primefaces 5.3? I checked the answer in here and searched on the web, but could not figure it out.
overwrite your the styles in your CSS and point to your icon image:
.ui-row-editor > .ui-icon-pencil {
background-image: url(../images/myPencil.png) !important;
height: 20px;
width:20px;
}
