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 = Proc.new {  
p “Open is called.”  
dialog = FileChooserDialog.new(“Open File”,nil,  
FileChooser::ACTION\_OPEN,nil,  
[Stock::CANCEL,Dialog::RESPONSE\_CANCEL],  
[Stock::OPEN,Dialog::RESPONSE\_ACCEPT])  
if dialog.run == Dialog::RESPONSE\_ACCEPT  
@filename = #{dialog.filename}  
file = File.open(@filename)

}

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 or if I just call File.open and pass the filename  
and rad it line by line. When  
I try to do that it outputs the text in the console not in my buffer.

Any help would be appreciated.

I believe something along a call to the following open\_file will do the  
trick.

def read\_file  
File.open(@filename){|f| ret = f.readlines.join }  
end

def open\_file  
text = read\_file  
@buffer.text= text  
end

view = Gtk::TextView.new  
@buffer = view.buffer

There is a simple texteditor on the home page (section samples). It may  
help.
