8.1. 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]
