Detailed Description

Enumeration Type Documentation

AnchorHints

enum class Gdk::AnchorHints

strong

Positioning hints for aligning a surface relative to a rectangle.

These hints determine how the surface should be positioned in the case that the surface would fall off-screen if placed in its ideal position.

For example, Gdk::AnchorHints::FLIP_X will replace Gdk::Gravity::NORTH_WEST with Gdk::Gravity::NORTH_EAST and vice versa if the surface extends beyond the left or right edges of the monitor.

If Gdk::AnchorHints::SLIDE_X is set, the surface can be shifted horizontally to fit on-screen. If Gdk::AnchorHints::RESIZE_X is set, the surface can be shrunken horizontally to fit.

In general, when multiple flags are set, flipping should take precedence over sliding, which should take precedence over resizing.

Bitwise operators:

AnchorHints operator|(AnchorHints, AnchorHints)
AnchorHints operator&(AnchorHints, AnchorHints)
AnchorHints operator^(AnchorHints, AnchorHints)
AnchorHints operator~(AnchorHints)
AnchorHints& operator|=(AnchorHints&, AnchorHints)
AnchorHints& operator&=(AnchorHints&, AnchorHints)
AnchorHints& operator^=(AnchorHints&, AnchorHints)

Enumerator
FLIP_X	Allow flipping anchors horizontally.
FLIP_Y	Allow flipping anchors vertically.
SLIDE_X	Allow sliding surface horizontally.
SLIDE_Y	Allow sliding surface vertically.
RESIZE_X	Allow resizing surface horizontally.
RESIZE_Y	Allow resizing surface vertically.
FLIP	Allow flipping anchors on both axes.
SLIDE	Allow sliding surface on both axes.
RESIZE	Allow resizing surface on both axes.

AxisFlags

enum class Gdk::AxisFlags

strong

Flags describing the current capabilities of a device/tool.

Bitwise operators:

AxisFlags operator|(AxisFlags, AxisFlags)
AxisFlags operator&(AxisFlags, AxisFlags)
AxisFlags operator^(AxisFlags, AxisFlags)
AxisFlags operator~(AxisFlags)
AxisFlags& operator|=(AxisFlags&, AxisFlags)
AxisFlags& operator&=(AxisFlags&, AxisFlags)
AxisFlags& operator^=(AxisFlags&, AxisFlags)

Enumerator
X	X axis is present.
Y	Y axis is present.
DELTA_X	Scroll X delta axis is present.
DELTA_Y	Scroll Y delta axis is present.
PRESSURE	Pressure axis is present.
XTILT	X tilt axis is present.
YTILT	Y tilt axis is present.

DISTANCE	Distance axis is present.
ROTATION	Z-axis rotation is present.
SLIDER	Slider axis is present.

AxisUse

enum class Gdk::AxisUse

strong

Defines how device axes are interpreted by GTK.

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.

Enumerator
IGNORE	The axis is ignored.
X	The axis is used as the x axis.
Y	The axis is used as the y axis.
DELTA_X	The axis is used as the scroll x delta.
DELTA_Y	The axis is used as the scroll y delta.
PRESSURE	The axis is used for pressure information.
XTILT	The axis is used for x tilt information.
YTILT	The axis is used for y tilt information.
WHEEL	The axis is used for wheel information.
DISTANCE	The axis is used for pen/tablet distance information.
ROTATION	The axis is used for pen rotation information.
SLIDER	The axis is used for pen slider information.
LAST	A constant equal to the numerically highest axis value.

Capabilities

enum class Gdk::Seat::Capabilities

strong

Flags describing the seat capabilities.

Bitwise operators:

Seat::Capabilities operator|(Seat::Capabilities, Seat::Capabilities)
Seat::Capabilities operator&(Seat::Capabilities, Seat::Capabilities)
Seat::Capabilities operator^(Seat::Capabilities, Seat::Capabilities)
Seat::Capabilities operator~(Seat::Capabilities)
Seat::Capabilities& operator|=(Seat::Capabilities&, Seat::Capabilities)
Seat::Capabilities& operator&=(Seat::Capabilities&, Seat::Capabilities)
Seat::Capabilities& operator^=(Seat::Capabilities&, Seat::Capabilities)

Enumerator
NONE	No input capabilities.
POINTER	The seat has a pointer (e.g. mouse).
TOUCH	The seat has touchscreen(s) attached.
TABLET_STYLUS	The seat has drawing tablet(s) attached.
KEYBOARD	The seat has keyboard(s) attached.
TABLET_PAD	The seat has drawing tablet pad(s) attached.
ALL_POINTING	The union of all pointing capabilities.
ALL	The union of all capabilities.

Colorspace

enum class Gdk::Colorspace

strong

This enumeration defines the color spaces that are supported by the gdk-pixbuf library.

Currently only RGB is supported.

Enumerator
RGB	Indicates a red/green/blue additive color space.

CrossingMode

enum class Gdk::CrossingMode

strong

Specifies the crossing mode for enter and leave events.

Enumerator
NORMAL	Crossing because of pointer motion.
GRAB	Crossing because a grab is activated.
UNGRAB	Crossing because a grab is deactivated.
GTK_GRAB	Crossing because a GTK grab is activated.
GTK_UNGRAB	Crossing because a GTK grab is deactivated.

Format

enum class Gdk::MemoryTexture::Format

strong

Gdk::MemoryFormat describes formats that image data can have in memory.

Prefer Gdk::MemoryFormat to Gdk::MemoryTexture::Format where possible.

It describes formats by listing the contents of the memory passed to it. So Gdk::MemoryFormat::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::Surface::Format::ARGB32 is represented by different Gdk::MemoryFormats on architectures with different endiannesses.

Its naming is modelled after VkFormat for details).

Gdk::MemoryFormat and Gdk::MemoryTexture::Format are identical. It's possible to convert between them with static_cast.

InterpType

enum class Gdk::InterpType

strong

Interpolation modes for scaling functions.

The Gdk::InterpType::NEAREST mode is the fastest scaling method, but has horrible quality when scaling down; Gdk::InterpType::BILINEAR is the best choice if you aren't sure what to choose, it has a good speed/quality balance.

Note: Cubic filtering is missing from the list; hyperbolic interpolation is just as fast and results in higher quality.

Enumerator
NEAREST	Nearest neighbor sampling; this is the fastest and lowest quality mode. Quality is normally unacceptable when scaling down, but may be OK when scaling up.
TILES	This is an accurate simulation of the PostScript image operator without any interpolation enabled. Each pixel is rendered as a tiny parallelogram of solid color, the edges of which are implemented with antialiasing. It resembles nearest neighbor for enlargement, and bilinear for reduction.
BILINEAR	Best quality/speed balance; use this mode by default. Bilinear interpolation. For enlargement, it is equivalent to point-sampling the ideal bilinear-interpolated image. For reduction, it is equivalent to laying down small tiles and integrating over the coverage area.
HYPER	This is the slowest and highest quality reconstruction function. It is derived from the hyperbolic filters in Wolberg's "Digital Image Warping", and is formally defined as the hyperbolic-filter sampling the ideal hyperbolic-filter interpolated image (the filter is designed to be idempotent for 1:1 pixel mapping). Deprecated: this interpolation filter is deprecated, as in reality it has a lower quality than the GDK_INTERP_BILINEAR filter (Since: 2.38).

KeyMatch

enum class Gdk::KeyMatch

strong

EXACT	The key event matches.

MemoryFormat

enum class Gdk::MemoryFormat

strong

Gdk::MemoryFormat describes formats that image data can have in memory.

It describes formats by listing the contents of the memory passed to it. So Gdk::MemoryFormat::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::Surface::Format::ARGB32 is represented by different Gdk::MemoryFormats on architectures with different endiannesses.

Range

enum class Gdk::CicpParams::Range

strong

The values of this enumeration describe whether image data uses the full range of 8-bit values.

In digital broadcasting, it is common to reserve the lowest and highest values. Typically the allowed values for the narrow range are 16-235 for Y and 16-240 for u,v (when dealing with YUV data).

Since gtkmm 4.16:

Enumerator
NARROW	The values use the range of 16-235 (for Y) and 16-240 for u and v.
FULL	The values use the full range.

Rotation

enum class Gdk::Pixbuf::Rotation

strong

Enumerator
UP	The surface is scrolled up.
DOWN	The surface is scrolled down.
LEFT	The surface is scrolled to the left.
RIGHT	The surface is scrolled to the right.
SMOOTH	The scrolling is determined by the delta values in scroll events. See gdk_scroll_event_get_deltas().

ScrollUnit

enum class Gdk::ScrollUnit

strong

Specifies the unit of scroll deltas.

When you get Gdk::ScrollUnit::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::ScrollUnit::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).

Since gtkmm 4.8:

Enumerator
WHEEL	The delta is in number of wheel clicks.
SURFACE	The delta is in surface pixels to scroll directly on screen.

State

enum class Gdk::Toplevel::State

strong

Specifies the state of a toplevel surface.

On platforms that support information about individual edges, the Gdk::Toplevel::State::TILED state will be set whenever any of the individual tiled states is set. On platforms that lack that support, the tiled state will give an indication of tiledness without any of the per-edge states being set.

Bitwise operators:

Toplevel::State operator|(Toplevel::State, Toplevel::State)
Toplevel::State operator&(Toplevel::State, Toplevel::State)
Toplevel::State operator^(Toplevel::State, Toplevel::State)

TouchpadGesturePhase

enum class Gdk::TouchpadGesturePhase

strong

Specifies the current state of a touchpad gesture.

All gestures are guaranteed to begin with an event with phase Gdk::TouchpadGesturePhase::BEGIN, followed by 0 or several events with phase Gdk::TouchpadGesturePhase::UPDATE.

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

Enumerator
BEGIN	The gesture has begun.
UPDATE	The gesture has been updated.
END	The gesture was finished, changes should be permanently applied.
CANCEL	The gesture was cancelled, all changes should be undone.
