Method OnFocusChanged

Namespace

Alternet.UI

Assembly

Alternet.UI.Maui.dll

OnFocusChanged(bool, FocusSearchDirection, Rect?)

Called by the view system when the focus state of this view changes.

protected override void OnFocusChanged(bool gainFocus, FocusSearchDirection direction, Rect? previouslyFocusedRect)

Parameters

gainFocus bool

True if the View has focus; false otherwise.

direction FocusSearchDirection

The direction focus has moved when requestFocus() is called to give this view focus. Values are #FOCUS_UP, #FOCUS_DOWN, #FOCUS_LEFT, #FOCUS_RIGHT, #FOCUS_FORWARD, or #FOCUS_BACKWARD. It may not always apply, in which case use the default.

previouslyFocusedRect Rect

The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be null otherwise.

Remarks

Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.
