This would allow to enable, configure or disable drag ability of a GimpColorArea ater its creation. I tested that it works correctly in binding. For instance in Python: > area.enable_drag(0) > area.enable_drag(Gdk.ModifierType.BUTTON1_MASK | > Gdk.ModifierType.BUTTON2_MASK) … correctly disable then reanable the drag with buttons 1 and 2 (in particular, I wanted to verify there was any reason why the property was G_PARAM_CONSTRUCT_ONLY. Turns out there was no good reason). I was interested by such API because having long list of parameters in various APIs is very annoying. It is much nicer to have simple constructors with decent defaults and proper API to modify a widget afterwards in order to cater to special needs.
