How to split the display in 2 scenes, and choosing what is displayed
====================================================================

In this example, we will set the scene layout to 2 horizontal scenes and set one of the views to 3D with a dataset.

First, we split the scene::

    from OrsPythonPlugins.OrsLayoutManager.OrsLayoutManager import OrsLayoutManager
    layout_manager = OrsLayoutManager()
    layout_manager.setSceneLayout(2, vertical=False)
    layout_manager.deletePlugin()


Next, we will get the layout of scenes::

    from OrsHelpers.layoutHelper import LayoutHelper
    layout_of_scenes = LayoutHelper.getTopLayoutOfContext(None)

Each scene can have it's own layout. Each scene layout is in order from left to right, or top to bottom.
If you have a horizontal layout of scenes and you want the left most scene, you would choose the 1st layout from the layout of scenes::

    scene_layouts = layout_of_scenes.getAllChildLayout()
    left_scene = scene_layouts[0]


To get the views of a layout::

    views = left_scene.getAllChildViews()

To set one of the views to 3D::

    from COMWrapper.ORS_def import CxvView_Mode
    view = views[0]
    view.setViewMode(CxvView_Mode.CXVVIEW_MODE_3D)

To display an object in the layout, assuming that you have a Channel::

    from OrsHelpers.displayDatasetInLayout import DisplayDatasetInLayout
    DisplayDatasetInLayout.addChannelToLayout(channel, left_scene)

To get the channels in the layout, you can ask each of the views, but generally, asking one of the views is fine::

    from ORSModel import VisualChannel, Channel
    visualChannels = view.getAllVisibleChildrenOfClass(VisualChannel.getClassNameStatic())
    channels = [vc.getFirstParentOfClass(Channel.getClassNameStatic()) for vc in visualChannels]
