Removing folders

Development

I’ve been able to remove nodes with the RemoveNode() function, but I can’t find any corresponding function for non-Node objects, such as folders. Is there a function to remove folders, or a similar method?

It turns out that if you convert folders to “subject”

you can delete them with

# Get the MRML scene
scene = slicer.mrmlScene

# Get the folder node you want to remove. Replace 'FolderName' with your folder's name.
folderNode = scene.GetFirstNodeByName('MyFolder')

# If the node exists, then remove it
if folderNode:
     scene.RemoveNode(folderNode)
else: 
     print("Folder 'MyFolder' not found")


````

The preferred way seems to be:

shNode = slicer.mrmlScene.GetSubjectHierarchyNode()
exportFolderItemId = shNode.CreateFolderItem(shNode.GetSceneItemID(), "MyNewFolder")

# do something with the folder
# later ...

shNode.RemoveItem(exportFolderItemId)
