How do I create the 'left navigating toolbar' like the QT Creator does-CodePudding

I asked these questions because after saw the showcase of 'ADS' open source here:

https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System#getting-started--example

the ADS showcase is amazing, but it's not the point. ADS provides a freely docking widget manager system, but I want to add the 'left navigation tool bar' to convenient for switch different workpenchs.

You will have to copy-paste that class from Qt Creator sources. It doesn’t come with Qt.
