connectBegin
fun connectBegin(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (<Error class: unknown class>?) -> Unit): <Error class: unknown class>
Emitted when the gesture is recognized.
This means the number of touch sequences matches property@Gtk.Gesture:n-points.
Note: These conditions may also happen when an extra touch (eg. a third touch on a 2-touches gesture) is lifted, in that situation @sequence won't pertain to the current set of active touches, so don't rely on this being true.
Parameters
connectFlags
A combination of ConnectFlags
handler
the Callback to connect. Params: sequence the GdkEventSequence that made the gesture to be recognized
