Hi ,
Has anyone ever pass multiple parameters to a gtk_signal_connect
function ?
What I want to achieve is when I click on a button I want the text
contains in 3 different textbox (GTKEntry) processed by the function
that is called by the gtk_signal_connect of the button. If anyone has
a code example that might be very helpful since the examples in the
doc are all too simple...
cheers,
Sam
