Looking at the documentation for GdkEventButton [1], it seems like it
lets you detect whether the icon was only clicked once, double-clicked
or activated in another way. If you only want a simple click handler, I
assume you can ignore the parameter, or if you want a bit cleaner code,
leave the parameter out of your method declaration entirely and use
sigc::hide [2] to make your functor compatible to the signal, e.g.:
void MyClass::on_icon_release(Gtk::EntryIconPosition icon_position)
{
[...]
}
MyClass::MyClass
{
[...]
entry->signal_icon_release().connect(sigc::hide<1>(
sigc::mem_fun(this, &MyClass::on_icon_release)));
}
