IWpfKeyboardTrackingService Interface

Definition

Important

This API is not CLS-compliant.

Defines a MEF service responsible for tracking the keyboard in hosts of the WPF editor. Keyboard tracking is necessary as some hosts (such as VisualStudio) do their own keyboard handling, causing inconsistent behavior of WPF elements, even when they have keyboard focus. By tracking the keyboard, all keyboard events will be routed to WPF first, giving focused WPF controls a shot at handling keyboard events.

Attributes

Remarks

Keyboard tracking is necessary because some hosts, such as VisualStudio, do their own keyboard handling, causing inconsistent behavior with WPF elements even when they have keyboard focus. By tracking the keyboard, all keyboard events will be routed to WPF first, giving focused WPF controls a chance to handle keyboard events in a consistent manner.

Methods

BeginTrackingKeyboard(IntPtr, IList<UInt32>)

Starts tracking the keyboard. Once called, all keyboard events will be routed to WPF first, before the host application sees them.

EndTrackingKeyboard()

Stops tracking the keyboard.
