gtkmm_problem
 

Hi, I have a school project I have to make a simple program that looks like an editor...but for web design(html).
So I made a grafic with a text buffer, a combobox, a treeview and an menu bar.
My question is when I push File > Open and I select the file how do I put the content of that file in textbuffer?
thx
This is link of a screenshot of the program, how it looks...it's very simple and ugly...I have only 2 days to finish it.
