class Gtk::GestureLongPress

Overview

Gtk::GestureLongPress is a Gtk::Gesture for long presses.

This gesture is also known as “Press and Hold”.

When the timeout is exceeded, the gesture is triggering the Gtk::GestureLongPress::#pressed signal.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the Gtk::GestureLongPress::#cancelled signal will be emitted.

How long the timeout is before the ::pressed signal gets emitted is determined by the [property@Gtk.Settings:gtk-long-press-time] setting. It can be modified by the [property@Gtk.GestureLongPress:delay-factor] property.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/gesture_long_press.cr
