title: How to block entering a Gtk CellRendererText edit mode?
body: <p>So basically what I'm trying to do here is to not allow entering of edit mode when there was a drag done. In a very brief way, click on celrenderer text = enter edit mode. drag = no edit mode. click meaning button press and release almost at same position. This could have been way easier if the celrenderertext was a widget but the way it is... I dont see how I could do something like that.</p>
  <p>in the documentation I only see signals for when the diting is over or function which get the widget displayed in edit mode, etc... but I cant find something which could directly help me here.</p>
  <p>Maybe somehow add an event box or something.</p>
  <p>I'm specifically using gtkmm here.</p>
