Is it possible to have the CombinedManipulator use left click instead of right in Helix Toolkit WPF?

I'm using the CombinedManipulator and everything is working great, but I'd like to change it to use left click instead of right. I've looked through all the docs and I haven't found anything that would help me. I did see this but I couldn't seem to implement it correctly.

Heres my HelixViewport xaml:

<helix:HelixViewport3D x:Name="viewPort3d" ZoomExtentsWhenLoaded="true"
                           Margin="0,0,290.6,173.6" Background="Black" MouseLeftButtonUp="Viewport3D_MouseMove" 
                           SnapMouseDownPoint="False" Height="638" VerticalAlignment="Bottom" 
                           ShowCameraInfo="True" MinimumFieldOfView="45" >
        <helix:DefaultLights/>
        <helix:CombinedManipulator x:Name="rTManipulator" CanRotateX="True" CanRotateY="True" CanRotateZ="True" />
</helix:HelixViewport3D>
Solution

  • The CombinedManipulator internally uses RotateManipulator and TranslateManipulator which in turn react to OnMouseDown and OnMouseMove events (see source code here). I suggest you fork the project and edit the components to match your needs, ie filter on left/right click as you see fit. You can also submit a PR to the project which is still acively maintained.
