Method Detail

tabIndex

C tabIndex(int tabIndex)

Sets the tabindex attribute in the component. The tabIndex indicates if its element can be focused, and if/where it participates in sequential keyboard navigation:

• A negative value (usually tabindex = -1 means that the component should be focusable, but should not be reachable via sequential keyboard navigation.
• tabindex = 0 means that the component should be focusable in sequential keyboard navigation, but its order is defined by the document's source order.
• A positive value means the component should be focusable in sequential keyboard navigation, with its order defined by the value of the number. That is, tabindex = 4 would be focused before tabindex = 5, but after tabindex = 3. If multiple components share the same positive tabindex value, their order relative to each other follows their position in the document source.

Parameters:

tabIndex - The tab index to set

Returns:
