Articles in this series will describe solutions that are the results of our research. You can check this project’s repository to quickly look up the code you may find helpful when solving similar problems.
The IntelliJ Platform plugin series will explain how to solve intricate problems we encountered during the development of our own plugin and is a great way to showcase our open-source Kotlin SDK while doing so. While each article will focus on a narrow spectrum of functionalities (like the Drag and Drop Tree covered today), we assume you have the Pieces Suite installed if you want to try to develop an IntelliJ plugin by yourself while learning from our repo.
There is quite a bit going on in our view’s class, so we'll take it slow and go through its functions one by one, according to their importance. The first thing we need to do is to create the structure our items will fit into. com.intellij.ui.treeStructure.Tree seems to best match our needs, and that’s what we’ll use. In order to prepare it for what is coming, we need to configure it.
