Hi,
I've a window class which creates some HScale widgets based on a
saved file. So I create them dynamic with new and store the pointers in
a std::vector. This works great, but I could only connect all HScale
widgets to one callback function:
hscale->signal_value_changed ().connect (sigc::mem_fun (*this,
&Application::on_target_hscale_changed));
In this callback I like to get the correct HScale widget pointer whose
value was changed. I found this in docs:
http://libsigc.sourceforge.net/libsigc2/docs/manual/html/ch02s03.html
This reads like the stuff I need, but how could I use this with HScale?
Need I to derivate HScale and add this new signal with parameters? How
how could I do this?
regards
Andreas
