C++ (Cpp) FPointerEvent::IsRightControlDown Examples

Example #1

File: SceneViewport.cpp Project: 1vanK/AHRUnrealEngine

void FSceneViewport::UpdateModifierKeys( const FPointerEvent& InMouseEvent )
{
	KeyStateMap.Add( EKeys::LeftAlt, InMouseEvent.IsLeftAltDown() );
	KeyStateMap.Add( EKeys::RightAlt, InMouseEvent.IsRightAltDown() );
	KeyStateMap.Add(EKeys::LeftControl, InMouseEvent.IsLeftControlDown());
	KeyStateMap.Add(EKeys::RightControl, InMouseEvent.IsRightControlDown());
	KeyStateMap.Add(EKeys::LeftShift, InMouseEvent.IsLeftShiftDown());
	KeyStateMap.Add(EKeys::RightShift, InMouseEvent.IsRightShiftDown());
}

Example #2

File: TimeSliderController.cpp Project: PickUpSU/UnrealEngine4

FReply FSequencerTimeSliderController::OnMouseWheel( TSharedRef<SWidget> WidgetOwner, const FGeometry& MyGeometry, const FPointerEvent& MouseEvent )
{
	TOptional<TRange<float>> NewTargetRange;

	float MouseFractionX = MyGeometry.AbsoluteToLocal(MouseEvent.GetScreenSpacePosition()).X / MyGeometry.GetLocalSize().X;
	if ( TimeSliderArgs.AllowZoom && (MouseEvent.IsLeftControlDown() || MouseEvent.IsRightControlDown()) )
	{

		{
			return FReply::Handled();

	}
	else if (MouseEvent.IsLeftShiftDown() || MouseEvent.IsRightShiftDown())
	{
		PanByDelta(-MouseEvent.GetWheelDelta());
		return FReply::Handled();
	}
	
	return FReply::Unhandled();
