Highlight behavior

Highlighting helps users identify the item that they are initiating an action on. The highlight on a component behaves differently depending on the component and the context. If you use BlackBerry UI components, the highlight behaviour is built into the component.

Best practices for custom UI components

• If the expected interaction is binary, highlight the component when users touch it. Remove the highlight when users release their finger.
• If users scroll through a list or view (for example, a grid view), do not highlight individual items.
• If an item requires continuous interaction (for example, a slider), highlight the item until users release their finger. In this case, you might need to lock other items that allow scrolling, such as lists.
• Don't allow users to highlight items that they cannot initiate an action on. Disable (dim) components or remove them from the screen.
