Enumerations
AxisUse
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 |
| AxisUseRotation | the axis is used for pen rotation information |
| AxisUseSlider | the axis is used for pen slider information |
| AxisUseLast | a constant equal to the numerically highest axis value. |

MemoryFormat
data MemoryFormat Source #
MemoryFormat describes a format that bytes can have in memory.
It describes formats by listing the contents of the memory passed to it.
So GDK_MEMORY_A8R8G8B8 will be 1 byte (8 bits) of alpha, followed by a
byte each of red, green and blue. It is not endian-dependent, so
CAIRO_FORMAT_ARGB32 is represented by different GdkMemoryFormats on
architectures with different endiannesses.
Its naming is modelled after VkFormat (see
https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.htmlVkFormat
for details).
Constructors
| MemoryFormatB8g8r8a8Premultiplied | 4 bytes; for blue, green, red, alpha. The color values are premultiplied with the alpha value. |
| MemoryFormatA8r8g8b8Premultiplied | 4 bytes; for alpha, red, green, blue. The color values are premultiplied with the alpha value. |

| AnotherMemoryFormat Int | Catch-all for unknown values |
Instances
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).
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 |
| 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. |

Instances
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.
Constructors
| TouchpadGesturePhaseBegin | The gesture has begun. |
| TouchpadGesturePhaseUpdate | The gesture has been updated. |
| TouchpadGesturePhaseEnd | The gesture was finished, changes should be permanently applied. |
