Question about using ruby and gtk to make an app
I have a question about using ruby and ruby-gtk2. I have a simple gui
and am using SourceView as my text buffer and have added a menu to open
and save files. My question is how in the world to I open a file and
display it within my buffer?

so far my open method is:

callback_open = {
p "Open is called."
dialog ="Open File",nil,
@filename = #{dialog.filename}
file =


after the file variable line I have tried different things to actually
add the text to the buffer but none seem to work. I checked the API but
I'm not sure if their is a TextBuffer method that I can use to read in
the file line by line.

Any help would be appreciated.

Chapter 2: GUI Toolkits for Ruby

This is a long but good free sample chapter from the _Ruby Developer's Guide_.

The section on "Using the Glade GUI Builder" (gtk) is nice, but I wish
maybe for one or two more full examples of it. I think glade or
glade-type tools can have a big impact by keeping the GUI and your
application as interchangeable parts. It is also multi-platform.
