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.datasethelper import DatasetHelper
    DatasetHelper.setIsVisibleIn2D(channel, view, True)
    DatasetHelper.fitToView(channel, view)

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]
