Synopsis

Enumerations

AxisUse

data AxisUse Source #

An enumeration describing the way in which a device axis (valuator) maps onto the predefined valuator types that GTK+ understands.

Note that the X and Y axes are not really needed; pointer devices report their location via the x/y members of events regardless. Whether X and Y are present as axes depends on the GDK backend.

Constructors

AxisUseIgnore

the axis is ignored.

AxisUseX

the axis is used as the x axis.

AxisUseY

the axis is used as the y axis.

AxisUsePressure

the axis is used for pressure information.

AxisUseXtilt

the axis is used for x tilt information.

AxisUseYtilt

the axis is used for y tilt information.

AxisUseWheel

the axis is used for wheel information.

AxisUseDistance

the axis is used for pen/tablet distance information. (Since: 3.22)

AxisUseRotation

the axis is used for pen rotation information. (Since: 3.22)

AxisUseSlider

the axis is used for pen slider information. (Since: 3.22)

AxisUseLast

a constant equal to the numerically highest axis value.

ByteOrder

data ByteOrder Source #

A set of values describing the possible byte-orders for storing pixel values in memory.

Constructors

The values are stored with the least-significant byte first. For instance, the 32-bit value 0xffeecc would be stored in memory as 0xcc, 0xee, 0xff, 0x00.

ByteOrderMsbFirst

The values are stored with the most-significant byte first. For instance, the 32-bit value 0xffeecc would be stored in memory as 0x00, 0xff, 0xee, 0xcc.

data CrossingMode Source #

Specifies the crossing mode for EventCrossing.

Constructors

CrossingModeGtkGrab

crossing because a GTK+ grab is activated.

CrossingModeGtkUngrab

crossing because a GTK+ grab is deactivated.

CrossingModeStateChanged

crossing because a GTK+ widget changed state (e.g. sensitivity).

CrossingModeTouchBegin

crossing because a touch sequence has begun, this event is synthetic as the pointer might have not left the window.

CrossingModeTouchEnd

crossing because a touch sequence has ended, this event is synthetic as the pointer might have not left the window.

CrossingModeDeviceSwitch

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 window.

AnotherCrossingMode Int

Do not confuse these events with the signals that GTK+ widgets emit. Although many of these events result in corresponding signals being emitted, the events are often transformed or filtered along the way.

In some language bindings, the values EventType2buttonPress and EventType3buttonPress would translate into something syntactically invalid (eg Gdk.EventType.2ButtonPress, where a symbol is not allowed to start with a number). In that case, the aliases EventTypeDoubleButtonPress and EventTypeTripleButtonPress can be used instead.

ModifierIntent

data ModifierIntent Source #

This enum is used with keymapGetModifierMask in order to determine what modifiers the currently used windowing system backend uses for particular purposes. For example, on X11/Windows, the Control key is used for invoking menu shortcuts (accelerators), whereas on Apple computers it’s the Command key (which correspond to ModifierTypeControlMask and ModifierTypeMod2Mask, respectively).

Since: 3.4

Constructors

ModifierIntentPrimaryAccelerator

the primary modifier used to invoke menu accelerators.

ModifierIntentContextMenu

the modifier used to invoke context menus. Note that mouse button 3 always triggers context menus. When this modifier is not 0, it additionally triggers context menus when used with mouse button 1.

ModifierIntentExtendSelection

the modifier used to extend selections using modifier-click or modifier-cursor-key

ModifierIntentModifySelection

the modifier used to modify selections, which in most cases means toggling the clicked item into or out of the selection.

ModifierIntentNoTextInput

when any of these modifiers is pressed, the key event cannot produce a symbol directly. This is meant to be used for input methods, and for use cases like typeahead search.

ModifierIntentShiftGroup

the modifier that switches between keyboard groups (AltGr on X11/Windows and Option/Alt on OS X).

ModifierIntentDefaultModMask

The set of modifier masks accepted as modifiers in accelerators. Needed because Command is mapped to MOD2 on OSX, which is widely used, but on X11 MOD2 is NumLock and using that for a mod key is problematic at best. Ref: https://bugzilla.gnome.org/show_bug.cgi?id=736125.

TouchpadGesturePhase

data TouchpadGesturePhase Source #

Specifies the current state of a touchpad gesture. All gestures are guaranteed to begin with an event with phase TouchpadGesturePhaseBegin, followed by 0 or several events with phase TouchpadGesturePhaseUpdate.

A finished gesture may have 2 possible outcomes, an event with phase TouchpadGesturePhaseEnd 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 TouchpadGesturePhaseCancel, this should be used as a hint to undo any visible/permanent changes that were done throughout the progress of the gesture.

See also EventTouchpadSwipe and EventTouchpadPinch.

Constructors

TouchpadGesturePhaseBegin

The gesture has begun.

TouchpadGesturePhaseUpdate

The gesture has been updated.
