Detailed Description

"Press and Hold" gesture.

This is a Gesture implementation able to recognize long presses, triggering signal_pressed() after the timeout is exceeded.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, signal_cancelled() will be emitted.

Since gtkmm 3.14:

◆ signal_cancelled()

Glib::SignalProxy< void > Gtk::GestureLongPress::signal_cancelled ( )

◆ signal_pressed()

Glib::SignalProxy< void, double, double > Gtk::GestureLongPress::signal_pressed ( )

Slot Prototype:: void on_my_pressed(double x, double y)

Flags: Run Last

Since gtkmm 3.14:

Parameters

x	The X coordinate where the press happened, relative to the widget allocation.
y	The Y coordinate where the press happened, relative to the widget allocation.
