Check buttons inherit many properties and functions from the
toggle buttons above, but look a little different. Rather
than being buttons with text inside them, they are small
squares with the text to the right of them. These are often
used for toggling options on and off in applications.
The creation and use of check buttos is identical to that of
toggle buttons.
def callback(bttn)
puts (bttn.active? ? "Active" : "Not active")
end
# ...
check = Gtk::CheckButton.new "Button"
check.signal_connect('toggled') {callback(check)} |
