Signal

GtkGesture::begin

since: 3.14

Declaration

void
begin (
  GtkGesture* self,
  GdkEventSequence* sequence,
  gpointer user_data
)

Description [src]

This signal is emitted when the gesture is recognized. This means the number of touch sequences matches GtkGesture:n-points, and the GtkGesture::check handler(s) returned TRUE.

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.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 3.14

Parameters

sequence

Type: GdkEventSequence

The GdkEventSequence that made the gesture to be recognized.

The argument can be NULL.

The data is owned by the caller of the function.
