How to render a Widget inside a TreeView cell with GTK# <p>I'm developing an application with Mono and Gtk#. Inside my app, I need to use the TreeView control. I'm looking for a way to render a widget inside a cell instead of drawing everything. I have custom widgets that I would like to use inside those cells and I don't want to draw them manually.</p> <p>I have looked over documentations and forums but haven't found a way to do this. I don't think this is impossible since CellRendererCombo and CellRendererToggle seems to render a Widget.</p> <p>Thanks</p>
