Hide empty packages from Project Tree

Created April 23, 2018 15:48

Hello.

I need to customize project view tree and create a class extended from com.intellij.ide.projectView.impl.ProjectViewPane and override
com.intellij.ide.projectView.impl.ProjectViewPane#createStructure.

All works fine, but the tree still contains packages without files that match the filter. How can I remove or hide them from the tree?

You can register own `TreeStructureProvider` and implement the `modify` method.
It may process children and remove empty PsiDirectoryNode.
Note, that this approach is very incovenient, because you cannot create new folder to add new file.

Thanks, I will try this method.

Is it possible to add action to hide/show empty directories to Options of ProjectView?

Only if you create and register own AbstractProjectViewPane:

<projectViewPane implementation="your.custom.ProjectViewPane"/>

and extend AbstractProjectViewPane#addToolbarActions
