Remarks

Important

Although this interface is public, it is not intended to be implemented in application or framework-building scenarios. This interface is public because of the inheritance requirements for connecting the WPF core to the WPF framework. You can also use this interface as a casting mechanism to enforce that the input events and properties will come from either a FrameworkElement or FrameworkContentElement, which can be handled in the same input model. For more information, see WPF Architecture and also see Base Elements Overview.

Properties

Focusable	Gets or sets a value that indicates whether focus can be set to this element.
IsEnabled	Gets a value that indicates whether this element is enabled in the user interface (UI).
IsKeyboardFocused	Gets a value that indicates whether this element has keyboard focus.
IsKeyboardFocusWithin	Gets a value that indicates whether keyboard focus is anywhere inside the element bounds, including if keyboard focus is inside the bounds of any visual child elements.
IsMouseCaptured	Gets a value that indicates whether the mouse is captured to this element.
IsMouseDirectlyOver	Gets a value that indicates whether the mouse pointer is over this element in the strictest hit testing sense.
IsMouseOver	Gets a value that indicates whether the mouse pointer is located over this element (including visual children elements that are inside its bounds).
IsStylusCaptured	Gets a value that indicates whether the stylus is captured to this element.
IsStylusDirectlyOver	Gets a value that indicates whether the stylus is over this element in the strictest hit testing sense.
IsStylusOver	Gets a value that indicates whether the stylus is located over this element (or over visual child elements that are inside its bounds).
