as just mentioned by mr baedert.
I have never used gestures before, so a few questions.
Is left mouse button double click a preferable option for advanced user interaction compared to right button click in modern GTK/Gnome as mouse may have no right button any more?
When I use GtkGestureMultiPress for a GtkButton, do I then just ignore the Button clicked signal?
And can I use GtkGestureMultiPress for a GtkLabel? Because when I remember correctly, in old days label had no event box by default. So is connecting GtkGestureMultiPress enough, or would I first have to create and add an event box?
Sorry for these stupid questions, I think google or testing may answer them as well. But on the other hand, this thread can teach readers some modern GTK.
