Hello guys 🙂

Im learning GTK and im doing ruby project with GTK2 so how to use GTK2  
with my ruby script?

I create windows for the user but when the user cliked on the buttom i  
would like the result appear in the same GTK windows.  
For example this is a part of my script which work fine without GTK in a  
simply shell:

def menu  
puts “ ~~~~~~~~~~~~~~~~~~ 0 - start”  
puts “ ~~~~~~~~~~~~~~~~~~ 1 - see”  
puts “ ~~~~~~~~~~~~~~~~~~ 2 - take”  
puts “ ~~~~~~~~~~~~~~~~~~ 3 - more?”  
puts “ ~~~~~~~~~~~~~~~~~~ 4 - Convert GIF to PNG”  
puts “ ~~~~~~~~~~~~~~~~~~ 5 -Convert PNG to GIF”  
puts “ ~~~~~~~~~~~~~~~~~~ 6 - Choose mor options”  
end  
menu  
opt=""  
while (opt!=“0” && opt!=“1” && opt!=“2” && opt!=“3” && opt!=“4” &&  
opt!=“5” && opt!=“6”)  
puts “Choose your option (between 0 et 6)”  
opt=gets.chomp  
end

So now i would like to have six windows in GTK2 for the user wich using  
“gets.chomp” or another like this to save the user option and starting  
it.

I don’t know start a command of the script with GTK.So help me please im  
beginner 🙂

Thanx you.

Download the official source.

In ruby-gnome look at gtk2/ directory

there is a sample/ subdirectory.

You will find a few hundred different .rb files in total

I learned a lot from studying them.

You should look through them and run them. Then you know what ruby-gnome  
can do for you.

To your question:

“I don’t know start a command of the script with GTK.”

First, make a simple layout of what you need.

Then use specific widgets.

In your example, you could use a Gtk::Table and buttons into  
that table.
