Hi
I’ve been trying to work this out for a while. Basically how do I get a callback to only return if a button or other widget does a signal in the called sub
ie:
button->signal_connect('clicked->sub{do_someting
}
};
sub do_something {
button->signal_connect(‘clicked’=>sub{
do stuff with a value;
return value to original subroutine
}
I cant work out how to only return if the do_something button is clicked
Signals are just fancy ways to invoke a list of functions using a well-known name; they are synchronous to their emission, but the emission can happen at any time—especially signals like GtkButton::clicked, which is the result of a complex series of windowing system events.
