enum GdkCrossingMode |
GdkCrossingMode: @GDK_CROSSING_NORMAL: crossing because of pointer motion. @GDK_CROSSING_GRAB: crossing because a grab is activated. @GDK_CROSSING_UNGRAB: crossing because a grab is deactivated. @GDK_CROSSING_GTK_GRAB: crossing because a GTK grab is activated. @GDK_CROSSING_GTK_UNGRAB: crossing because a GTK grab is deactivated. @GDK_CROSSING_STATE_CHANGED: crossing because a GTK widget changed state (e.g. sensitivity). @GDK_CROSSING_TOUCH_BEGIN: crossing because a touch sequence has begun, this event is synthetic as the pointer might have not left the surface. @GDK_CROSSING_TOUCH_END: crossing because a touch sequence has ended, this event is synthetic as the pointer might have not left the surface. @GDK_CROSSING_DEVICE_SWITCH: crossing because of a device switch (i.e. a mouse taking control of the pointer after a touch device), this event is synthetic as the pointer didn’t leave the surface.
Specifies the crossing mode for enter and leave events.
Definition at line 351 of file gdkevents.h.
enum GdkEventType |
GdkEventType: @GDK_DELETE: the window manager has requested that the toplevel surface be hidden or destroyed, usually when the user clicks on a special icon in the title bar. @GDK_MOTION_NOTIFY: the pointer (usually a mouse) has moved. @GDK_BUTTON_PRESS: a mouse button has been pressed. @GDK_BUTTON_RELEASE: a mouse button has been released. @GDK_KEY_PRESS: a key has been pressed. @GDK_KEY_RELEASE: a key has been released. @GDK_ENTER_NOTIFY: the pointer has entered the surface. @GDK_LEAVE_NOTIFY: the pointer has left the surface. @GDK_FOCUS_CHANGE: the keyboard focus has entered or left the surface. @GDK_PROXIMITY_IN: an input device has moved into contact with a sensing surface (e.g. a touchscreen or graphics tablet). @GDK_PROXIMITY_OUT: an input device has moved out of contact with a sensing surface. @GDK_DRAG_ENTER: the mouse has entered the surface while a drag is in progress. @GDK_DRAG_LEAVE: the mouse has left the surface while a drag is in progress. @GDK_DRAG_MOTION: the mouse has moved in the surface while a drag is in progress. @GDK_DROP_START: a drop operation onto the surface has started. @GDK_SCROLL: the scroll wheel was turned @GDK_GRAB_BROKEN: a pointer or keyboard grab was broken. @GDK_TOUCH_BEGIN: A new touch event sequence has just started. @GDK_TOUCH_UPDATE: A touch event sequence has been updated. @GDK_TOUCH_END: A touch event sequence has finished. @GDK_TOUCH_CANCEL: A touch event sequence has been canceled. @GDK_TOUCHPAD_SWIPE: A touchpad swipe gesture event, the current state is determined by its phase field. @GDK_TOUCHPAD_PINCH: A touchpad pinch gesture event, the current state is determined by its phase field. @GDK_PAD_BUTTON_PRESS: A tablet pad button press event. @GDK_PAD_BUTTON_RELEASE: A tablet pad button release event. @GDK_PAD_RING: A tablet pad axis event from a "ring". @GDK_PAD_STRIP: A tablet pad axis event from a "strip". @GDK_PAD_GROUP_MODE: A tablet pad group mode change. @GDK_EVENT_LAST: marks the end of the GdkEventType enumeration.
Specifies the type of the event. GDK_TOUCHPAD_HOLD:
A touchpad hold gesture event, the current state is determined by its phase field.

enum GdkKeyMatch |
GdkKeyMatch: @GDK_KEY_MATCH_NONE: The key event does not match @GDK_KEY_MATCH_PARTIAL: The key event matches if keyboard state (specifically, the currently active group) is ignored @GDK_KEY_MATCH_EXACT: The key event matches
Describes how well an event matches a given keyval and modifiers.

enum GdkNotifyType |
GdkNotifyType: @GDK_NOTIFY_ANCESTOR: the surface is entered from an ancestor or left towards an ancestor. @GDK_NOTIFY_VIRTUAL: the pointer moves between an ancestor and an inferior of the surface. @GDK_NOTIFY_INFERIOR: the surface is entered from an inferior or left towards an inferior. @GDK_NOTIFY_NONLINEAR: the surface is entered from or left towards a surface which is neither an ancestor nor an inferior. @GDK_NOTIFY_NONLINEAR_VIRTUAL: the pointer moves between two surfaces which are not ancestors of each other and the surface is part of the ancestor chain between one of these surfaces and their least common ancestor. @GDK_NOTIFY_UNKNOWN: an unknown type of enter/leave event occurred.
Specifies the kind of crossing for enter and leave events.
See the X11 protocol specification of LeaveNotify for full details of crossing event generation.

enum GdkScrollDirection |
GdkScrollDirection: @GDK_SCROLL_UP: the surface is scrolled up. @GDK_SCROLL_DOWN: the surface is scrolled down. @GDK_SCROLL_LEFT: the surface is scrolled to the left. @GDK_SCROLL_RIGHT: the surface is scrolled to the right. @GDK_SCROLL_SMOOTH: the scrolling is determined by the delta values in scroll events. See gdk_scroll_event_get_deltas()
Specifies the direction for scroll events.

enum GdkScrollUnit |
GdkScrollUnit: @GDK_SCROLL_UNIT_WHEEL: The delta is in number of wheel clicks. @GDK_SCROLL_UNIT_SURFACE: The delta is in surface pixels to scroll directly on screen.
Specifies the unit of scroll deltas.
When you get GDK_SCROLL_UNIT_WHEEL, a delta of 1.0 means 1 wheel detent click in the south direction, 2.0 means 2 wheel detent clicks in the south direction... This is the same logic for negative values but in the north direction.
If you get GDK_SCROLL_UNIT_SURFACE, are managing a scrollable view and get a value of 123, you have to scroll 123 surface logical pixels right if it's @delta_x or down if it's @delta_y. This is the same logic for negative values but you have to scroll left instead of right if it's @delta_x and up instead of down if it's @delta_y.
1 surface logical pixel is equal to 1 real screen pixel multiplied by the final scale factor of your graphical interface (the product of the desktop scale factor and eventually a custom scale factor in your app).

GdkTouchpadGesturePhase: @GDK_TOUCHPAD_GESTURE_PHASE_BEGIN: The gesture has begun. @GDK_TOUCHPAD_GESTURE_PHASE_UPDATE: The gesture has been updated. @GDK_TOUCHPAD_GESTURE_PHASE_END: The gesture was finished, changes should be permanently applied. @GDK_TOUCHPAD_GESTURE_PHASE_CANCEL: The gesture was cancelled, all changes should be undone.
Specifies the current state of a touchpad gesture.
All gestures are guaranteed to begin with an event with phase GDK_TOUCHPAD_GESTURE_PHASE_BEGIN, followed by 0 or several events with phase GDK_TOUCHPAD_GESTURE_PHASE_UPDATE.
A finished gesture may have 2 possible outcomes, an event with phase GDK_TOUCHPAD_GESTURE_PHASE_END will be emitted when the gesture is considered successful, this should be used as the hint to perform any permanent changes.
Cancelled gestures may be so for a variety of reasons, due to hardware or the compositor, or due to the gesture recognition layers hinting the gesture did not finish resolutely (eg. a 3rd finger being added during a pinch gesture). In these cases, the last event will report the phase GDK_TOUCHPAD_GESTURE_PHASE_CANCEL, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.
