Tracking editor tab if it was reopened in a different split or window?

IntelliJ Platform
1

Hey,

I have a FileEditorManagerListener implementation that displays a balloon notification for eligible files on file open. I override the fileOpened(FileEditorManager, VirtualFile) method for that.

class FileOpenListener: FileEditorManagerListener {
  override fun fileOpened(source: FileEditorManager, file: VirtualFile) {
    //Check file eligibility

    //Show balloon if file is eligible
  }
}

It works properly for simple cases, but I have faced a problem handling file editor movement to a different editor split or IDE window (e.g via drag-and-drop).

I’m trying to avoid showing the balloon in those cases to not annoy users with it in such cases.

I see that such movements are not handled as actual movements/relocations of an editor, but instead as closing the file, and then reopening that same file. Unfortunately I haven’t found a way of checking if FileEditorManagerListener.fileOpened()is called after a tab move, or just from a simple file open.

I also saw the com.intellij.openapi.fileEditor.FileEditorManagerKeys#CLOSING_TO_REOPENdata key, but that is available only during file closing.

So my question is, is there a way to check if a file was reopened after a drag-and-drop or moving to a split?

I’d use EditorNotificationProvider instead of push notifications semantics, as you will have hard times covering all possible window manager situations now.

Or may be you simply need to implement debounce, like show only 1 notification per day

Thank you! Going with EditorNotificationProvider does make more sense in this case.
