Gdk::EventTouchpadPinch::EventTouchpadPinch | ( | ) |
Creates an invalid event object.
Calling any member functions other than operator bool() is undefined behavior. An invalid event object can be used in a function call, if the underlying C function expects a NULL GdkEventTouchpadPinch pointer.
|

Wraps a C event instance.
This constructor either acquires ownership of gobject, or copies it.
gobject | Event to wrap. |
make_a_copy | If false , the ownership of gobject is acquired, otherwise a copy is made. |

Returns the angle change in radians.
Negative angles denote counter- clockwise movements.
double Gdk::EventTouchpadPinch::get_dx | ( | ) | const |
Returns the movement delta in the X axis of the swipe focal point.
double Gdk::EventTouchpadPinch::get_dy | ( | ) | const |
Returns the movement delta in the Y axis of the swipe focal point.
int Gdk::EventTouchpadPinch::get_n_fingers | ( | ) | const |
Returns the number of fingers triggering the swipe.

Returns the X coordinate of the pointer relative to the root of the screen.
double Gdk::EventTouchpadPinch::get_root_y | ( | ) | const |
Returns the Y coordinate of the pointer relative to the root of the screen.
double Gdk::EventTouchpadPinch::get_scale | ( | ) | const |
Returns the current scale, relative to that at the time of the corresponding Gdk::TouchpadGesturePhase::BEGIN event.
ModifierType Gdk::EventTouchpadPinch::get_state | ( | ) | const |
Returns a bit mask representing the state of the modifier keys (e.g.
Control, Shift and Alt) and the pointer buttons.
guint32 Gdk::EventTouchpadPinch::get_time | ( | ) | const |
Returns the timestamp of the event in milliseconds.
double Gdk::EventTouchpadPinch::get_x | ( | ) | const |

A Glib::wrap() method for this object.

take_copy | false if the result should take ownership of the C instance, true if it should take a new copy. |
|
related |
Wraps a C event instance without making unnecessary copy when the ownership can not be acquired.
The event pointer must not be deleted until last usage of the returned instance. Note, that this requirement applies to the pointer itself, in addition to the object it is pointing to.
