Instance Method Details

#make_class ⇒ Object

Runs the ruby-glade-create-template script to create a file with a class that corresponds to the form. This can be called repeatedly to keep creating the class every time the .glade file changes.

def make_class
	`/usr/bin/ruby-glade-create-template #{@glade_filename} > #{@class_filename}`
	@class_filename
end

#make_main ⇒ Object

Creates a main program that uses the glade class created with make_class and opens the window with the form. It will do nothing if the main program file already exists, since the user is likely to add code to this file.
