ContentElement::PreviewMouseWheel Event
Occurs when the user rotates the mouse wheel while the mouse pointer is over this element.
Assembly: PresentationCore (in PresentationCore.dll)
public: event MouseWheelEventHandler^ PreviewMouseWheel { virtual void add(MouseWheelEventHandler^ value) sealed; virtual void remove(MouseWheelEventHandler^ value) sealed; }
Implements
IInputElement::PreviewMouseWheelFocus or mouse capture take precedence over where the mouse pointer is; therefore, if you receive this event from a focused or captured element, the mouse pointer might actually be over another element.
This event creates an alias for the Mouse::PreviewMouseWheel attached event for this class, so that PreviewMouseMove is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the PreviewMouseMove event are attached to the underlying Mouse::PreviewMouseWheel attached event and receive the same event data instance.
