ListViewA vertically scrollable area that only creates visual elements for visible items while allowing the binding of many more items. As the user scrolls, visual elements are recycled and re-bound to new data items.
ManipulatorBase class for objects that define user interaction with a VisualElement. Most often manipulators hold state for complex interactions, for example interactions that require a mouse down, mouse move mouse up sequence.
MinMaxSliderA min/max slider containing a representation of a range.
MouseCaptureControllerClass that manages capturing mouse events.
MouseCaptureEventEvent sent after a handler starts capturing the mouse.
MouseCaptureEventBase<T0>Event sent when the handler capturing the mouse changes.
