The Dojo Mobile Android and iPhone themes contain default icons that can be used in widgets, such as dojox.mobile.ListItem and dojox.mobile.ToolBarButton widgets. These icons all start with the prefix “mblDomButton”. I could not find a detailed list of these icons, so I searched through the Android and iPhone CSS files to find everything with the mblDomButton prefix. I have an Android and iPhone page listing these icons and displaying them, both shown below.
