Sidepanel with Qt

I'd like to implement a sidepanel in my Qt window. I search something like the one that is used in the Visual Studio (see below).

Important notes:

• The widgets don't have to be moveable
• resizing should be possible
• each widget should be clearly separated from the other layout

Does anyone have an idea how I could build such a sidepanel? (Maybe there even exists a library) Or does anyone know a project which u开发者_开发问答ses Qt and some kind of sidepanel?

One option would be to use QDockWidgets. That's the type of thing they are intended for inside a QMainWindow.

You can put toolbars, QTreeViews and QTableViews (or related) widgets inside your dock widget to simulate the screenshot you posted.
