gtk signal for moving a scale(slider)?

Question

Simple question:

I've added some scales (sliders) to my window, and I want to call a method when you move the scale.

What is the signal name that I use for gtk_signal_connect? ie I should be able to write something like:

gtk_signal_connect(GTK_OBJECT(my_scale), "scale_moved", (GtkSignalFunc)my_event, data);

or am I missing something here?

And more importantly - how do I find out in the future what the signal names are? for example - I googled 'gtk_signal_connect' but I didn't find a big list of different signals.

Similarly, I didn't find details about related signals in the GtkScale documentation. (Well, in this page, there is a single signal detail, but it relates to changing the displayed value format).

Answer 1

GtkScale inherits from GtkRange, and signals are inherited in GTK+. Therefore, you can connect to the value-changed signal exposed by GtkRange.

You're on the right track to find the signals exposed by a given GTK+ widget: besides the source code itself, the documentation is indeed the canonical resource, but you should also take the base classes into account in your search.
