QtWin32DirectManipulateHelper

A Qt integration of Win32 Direct Manipulate APIs

Usage

To enable Direct Manipulation on a QWindow, call

QWDMH::DirectManipulationSystem::registerWindow(window);

To disable, call

QWDMH::DirectManipulationSystem::unregisterWindow(window);

After Direct Manipulation is enabled on a QWindow, a QNativeGestureEvent with QNativeGestureEvent::gestureType() to be Qt::ZoomNativeGesture will be sent when the user pinches on the touchpad, and a QWheelEvent will be sent when the user swipes on the touchpad with two fingers.

It is also supported to specify configuration and device type when registering a window, for example

QWDMH::DirectManipulationSystem::registerWindow(
    window,
    QWDMH::DirectManipulationSystem::TranslationX | QWDMH::DirectManipulationSystem::TranslationY,
    QWDMH::DirectManipulationSystem::Touchpad);

The example above makes the window processes only translation without inertia, and accepts input only from the touchpad.
