Specified by:

setAccessKey in interface Focusable

Parameters:

key - the widget's access key

setFocus

public void setFocus(boolean focused)

Description copied from interface: Focusable

Explicitly focus/unfocus this widget. Only one widget can have focus at a time, and the widget that does will receive all keyboard events. NOTE: Most browsers fire FocusEvents asynchronously. Especially within GWT tests, you'll need to make your test asynchronous to properly do verifications. See GWTTestCase#delayTestFinish for more information on how to do this.

Specified by:

setFocus in interface Focusable

Parameters:

focused - whether this widget should take focus or release it

setTabIndex

public void setTabIndex(int index)

Description copied from interface: Focusable

Sets the widget's position in the tab index. If more than one widget has the same tab index, each such widget will receive focus in an arbitrary order. Setting the tab index to -1 will cause this widget to be removed from the tab order.

Specified by:

setTabIndex in interface Focusable

Parameters:

index - the widget's tab index
