Interface IUIWindow3

interface IUIWindow3
Extends IUIWindow2 This interface extends IUIWindow2 to provide active keyboard-focus control. All methods of this interface, like IUIWindow, must be called on the UI thread.

Methods

setKeyboardFocus()

void setKeyboardFocus()
Requests the window manager to set keyboard focus on this window. Behavior, reset conditions, and the parent-child constraint are as documented on com.amazon.kepler.graphics.IWindow3::setKeyboardFocus, which this method delegates to.

Throws

  • BaseError — if the request cannot be fulfilled or the window is not in a valid state.
