This is my first post on this forum
I am wondering how to configure a Gtk TreeView so that it looks exactly the same as in the MonoDevelop "Properties" pad.
all the columns in the row for the toplevel nodes are merged and have a grey background. This gives a distict "group" look for all its child nodes.
resize the columns by the column gridlines (now it only works by the column separator in the header)
I have attached a screenshot to show what I want ..
