How to have a popup window similar to this on the ThreeSideView editor?

Answered

Hello. I want to show a popup window similar to below after hovering over a certain line while viewing a three-way diff (in the editor). I just want to know how to get this type of popup information design. My plan is to display information about a particular line being hovered on and be able to also run an action relating to that line. How could I get started on showing this type of window?

The underlying UI is built using com.intellij.openapi.ui.popup.JBPopupFactory, see com.intellij.openapi.editor.EditorMouseHoverPopupManager that generates above popup based on HighlightInfo
