Hi, I want to create simple file manager using Ruby & Gtk3. I found an  
example but they used python.

> **[Advanced widgets in PyGTK](https://zetcode.com/gui/pygtk/advancedwidgets/)**

I didn’t understand structure of List Store how works? Also I read this  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AListStore](http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AListStore)

I couldn’t put any argument to store.append function so I used like  
below:

@store = Gtk::ListStore.new(String, Gdk::Pixbuf, TrueClass)

Dir.foreach(“/path/”) {|x| @store.append; @store.set\_value(x, dir\_icon,  
true)}

But it doesn’t work, how should I use List Store?

Thanks.

Could you show the current whole your code?  
It will be a good start point to improve it.

## Thanks,

I found an example about list store and solved my problem.
