## Detailed Description

## Enumeration Type Documentation

## ◆ AnchorHints

enum Gdk::AnchorHints

Positioning hints for aligning a window relative to a rectangle.

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

For example, Gdk::ANCHOR_FLIP_X will replace Gdk::GRAVITY_NORTH_WEST with Gdk::GRAVITY_NORTH_EAST and vice versa if the window extends beyond the left or right edges of the monitor.

If Gdk::ANCHOR_SLIDE_X is set, the window can be shifted horizontally to fit on-screen. If Gdk::ANCHOR_RESIZE_X is set, the window 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.

Since: 3.22 Stability: Unstable

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)`

## ◆ AxisUse

enum Gdk::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.

DEVICE_TYPE_SLAVE | Device is a slave (or physical) device.
DEVICE_TYPE_FLOATING | Device is a physical device, currently not attached to any virtual device.

## ◆ DragAction

enum Gdk::DragAction

Used in Gdk::DragContext to indicate what the destination should do with the dropped data.

Bitwise operators:
  `DragAction operator|(DragAction, DragAction)`
  `DragAction operator&(DragAction, DragAction)`
  `DragAction operator^(DragAction, DragAction)`
  `DragAction operator~(DragAction)`
  `DragAction& operator|=(DragAction&, DragAction)`
  `DragAction& operator&=(DragAction&, DragAction)`
  `DragAction& operator^=(DragAction&, DragAction)`

Enumerator
ACTION_DEFAULT | Means nothing, and should not be used.
ACTION_COPY | Copy the data.
ACTION_MOVE | Move the data, i.e. first copy it, then delete it from the source using the DELETE target of the X selection protocol.
ACTION_LINK | Add a link to the data. Note that this is only useful if source and destination agree on what it means.
ACTION_PRIVATE | Special action which tells the source that the destination will do something that the source doesn’t understand.
ACTION_ASK | Ask the user what to do with the data.

## ◆ DragProtocol

enum Gdk::DragProtocol

Used in Gdk::DragContext to indicate the protocol according to which DND is done.

Enumerator
DRAG_PROTO_NONE | No protocol.
DRAG_PROTO_MOTIF | The Motif DND protocol. No longer supported.
DRAG_PROTO_XDND | The Xdnd protocol.
DRAG_PROTO_ROOTWIN | An extension to the Xdnd protocol for unclaimed root window drops.
DRAG_PROTO_WIN32_DROPFILES | The simple WM_DROPFILES protocol.
DRAG_PROTO_OLE2 | The complex OLE2 DND protocol (not implemented).
DRAG_PROTO_LOCAL | Intra-application DND.
DRAG_PROTO_WAYLAND | Wayland DND protocol.

## ◆ EventMask

enum Gdk::EventMask

A set of bit-flags to indicate which events a window is to receive.

Most of these masks map onto one or more of the Gdk::EventType event types above.

See the [input handling overview][chap-input-handling] for details of [event masks][event-masks] and [event propagation][event-propagation].

Gdk::POINTER_MOTION_HINT_MASK is deprecated. It is a special mask to reduce the number of Gdk::MOTION_NOTIFY events received. When using Gdk::POINTER_MOTION_HINT_MASK, fewer Gdk::MOTION_NOTIFY events will be sent, some of which are marked as a hint (the is_hint member is `true`). To receive more motion events after a motion hint event, the application needs to asks for more, by calling Gdk::Event::request_motions().

Since GTK 3.8, motion events are already compressed by default, independent of this mechanism. This compression can be disabled with Gdk::Window::set_event_compression(). See the documentation of that function for details.

If Gdk::TOUCH_MASK is enabled, the window will receive touch events from touch-enabled devices. Those will come as sequences of Gdk::EventTouch with type Gdk::TOUCH_UPDATE, enclosed by two events with type Gdk::TOUCH_BEGIN and Gdk::TOUCH_END (or Gdk::TOUCH_CANCEL). Gdk::Event::get_event_sequence() returns the event sequence for these events, so different sequences may be distinguished.

Bitwise operators:
  `EventMask operator|(EventMask, EventMask)`
  `EventMask operator&(EventMask, EventMask)`
  `EventMask operator^(EventMask, EventMask)`
  `EventMask operator~(EventMask)`
  `EventMask& operator|=(EventMask&, EventMask)`
  `EventMask& operator&=(EventMask&, EventMask)`
  `EventMask& operator^=(EventMask&, EventMask)`

ALL_EVENTS_MASK | The combination of all the above event masks.

## ◆ EventType

enum Gdk::EventType

Specifies the type of the event.

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 Gdk::2BUTTON_PRESS and Gdk::3BUTTON_PRESS 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 Gdk::DOUBLE_BUTTON_PRESS and Gdk::TRIPLE_BUTTON_PRESS can be used instead.

Enumerator

MODE_SCREEN | The device is enabled. The device’s coordinate space maps to the entire screen.
MODE_WINDOW | The device is enabled. The device’s coordinate space is mapped to a single window. The manner in which this window is chosen is undefined, but it will typically be the same way in which the focus window for key events is determined.

## ◆ InputSource

enum Gdk::InputSource

An enumeration describing the type of an input device in general terms.

Enumerator
SOURCE_MOUSE | The device is a mouse. (This will be reported for the core pointer, even if it is something else, such as a trackball.).
SOURCE_PEN | The device is a stylus of a graphics tablet or similar device.
SOURCE_ERASER | The device is an eraser. Typically, this would be the other end of a stylus on a graphics tablet.

## ◆ InterpType

enum Gdk::InterpType

This enumeration describes the different interpolation modes that can be used with the scaling functions.

GDK_INTERP_NEAREST is the fastest scaling method, but has horrible quality when scaling down. GDK_INTERP_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
INTERP_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.
INTERP_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.
INTERP_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.
INTERP_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).

## ◆ ModifierIntent

enum Gdk::ModifierIntent

This enum is used with Gdk::Keymap::get_modifier_mask() 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 Gdk::CONTROL_MASK and Gdk::MOD2_MASK, respectively).

Since gtkmm 3.4:

Enumerator
MODIFIER_INTENT_PRIMARY_ACCELERATOR | The primary modifier used to invoke menu accelerators.
MODIFIER_INTENT_CONTEXT_MENU | 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.
MODIFIER_INTENT_EXTEND_SELECTION | The modifier used to extend selections using `modifier`-click or `modifier`-cursor-key.
MODIFIER_INTENT_MODIFY_SELECTION | The modifier used to modify selections, which in most cases means toggling the clicked item into or out of the selection.
MODIFIER_INTENT_NO_TEXT_INPUT | 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.
MODIFIER_INTENT_SHIFT_GROUP | The modifier that switches between keyboard groups (AltGr on X11/Windows and Option/Alt on OS X).
MODIFIER_INTENT_DEFAULT_MOD_MASK | 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.

## ◆ ModifierType

enum Gdk::ModifierType

A set of bit-flags to indicate the state of modifier keys and mouse buttons in various event types.

Typical modifier keys are Shift, Control, Meta, Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.

Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.

Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped to Mod2 - Mod5, and indicates this by setting Gdk::SUPER_MASK, Gdk::HYPER_MASK or Gdk::META_MASK in the state field of key events.

Note that GDK may add internal values to events which include reserved values such as Gdk::MODIFIER_RESERVED_13_MASK. Your code should preserve and ignore them. You can use Gdk::MODIFIER_MASK to remove all reserved values.

Also note that the GDK X backend interprets button press events for button 4-7 as scroll events, so Gdk::BUTTON4_MASK and Gdk::BUTTON5_MASK will never be set.

Bitwise operators:
  `ModifierType operator|(ModifierType, ModifierType)`
  `ModifierType operator&(ModifierType, ModifierType)`
  `ModifierType operator^(ModifierType, ModifierType)`
  `ModifierType operator~(ModifierType)`
  `ModifierType& operator|=(ModifierType&, ModifierType)`
  `ModifierType& operator&=(ModifierType&, ModifierType)`
  `ModifierType& operator^=(ModifierType&, ModifierType)`

Enumerator
SHIFT_MASK | The Shift key.
LOCK_MASK | A Lock key (depending on the modifier mapping of the X server this may either be CapsLock or ShiftLock).
CONTROL_MASK | The Control key.
MOD1_MASK | The fourth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier, but normally it is the Alt key).
MOD2_MASK | The fifth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).
MOD3_MASK | The sixth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).
MOD4_MASK | The seventh modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).
MOD5_MASK | The eighth modifier key (it depends on the modifier mapping of the X server which key is interpreted as this modifier).
BUTTON1_MASK | The first mouse button.
BUTTON2_MASK | The second mouse button.
BUTTON3_MASK | The third mouse button.
BUTTON4_MASK | The fourth mouse button.

META_MASK | The Meta modifier. Since gtkmm 2.10:
MODIFIER_RESERVED_29_MASK | A reserved bit flag; do not use in your own code.
RELEASE_MASK | Not used in GDK itself. GTK+ uses it to differentiate between (keyval, modifiers) pairs from key press and release events.
MODIFIER_MASK | A mask covering all modifier types.

## ◆ PixbufAlphaMode

enum Gdk::PixbufAlphaMode

These values can be passed to gdk_pixbuf_xlib_render_to_drawable_alpha() to control how the alpha channel of an image should be handled.

This function can create a bilevel clipping mask (black and white) and use it while painting the image. In the future, when the X Window System gets an alpha channel extension, it will be possible to do full alpha compositing onto arbitrary drawables. For now both cases fall back to a bilevel clipping mask.

Enumerator
PIXBUF_ALPHA_BILEVEL | A bilevel clipping mask (black and white) will be created and used to draw the image. Pixels below 0.5 opacity will be considered fully transparent, and all others will be considered fully opaque.
PIXBUF_ALPHA_FULL | For now falls back to Gdk::PIXBUF_ALPHA_BILEVEL. In the future it will do full alpha compositing.

## ◆ PixbufRotation

## ◆ VisualType

enum Gdk::VisualType

A set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display.

Enumerator
VISUAL_STATIC_GRAY | Each pixel value indexes a grayscale value directly.
VISUAL_GRAYSCALE | Each pixel is an index into a color map that maps pixel values into grayscale values. The color map can be changed by an application.
VISUAL_STATIC_COLOR | Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.
VISUAL_PSEUDO_COLOR | Each pixel is an index into a color map that maps pixel values into rgb values. The color map can be changed by an application.
VISUAL_TRUE_COLOR | Each pixel value directly contains red, green, and blue components. Use Gdk::Visual::get_red_pixel_details(), etc, to obtain information about how the components are assembled into a pixel value.
VISUAL_DIRECT_COLOR | Each pixel value contains red, green, and blue components as for Gdk::VISUAL_TRUE_COLOR, but the components are mapped via a color table into the final output table instead of being converted directly.

## ◆ WindowAttributesType

enum Gdk::WindowAttributesType

Used to indicate which fields in the Gdk::WindowAttr struct should be honored.

For example, if you filled in the “cursor” and “x” fields of Gdk::WindowAttr, pass “ GDK_WA_X | GDK_WA_CURSOR” to Gdk::Window::new(). Fields in Gdk::WindowAttr not covered by a bit in this enum are required; for example, the width/ height, wclass, and window_type fields are required, they have no corresponding flag in Gdk::WindowAttributesType.

Bitwise operators:
  `WindowAttributesType operator|(WindowAttributesType, WindowAttributesType)`
  `WindowAttributesType operator&(WindowAttributesType, WindowAttributesType)`
  `WindowAttributesType operator^(WindowAttributesType, WindowAttributesType)`
  `WindowAttributesType operator~(WindowAttributesType)`
  `WindowAttributesType& operator|=(WindowAttributesType&, WindowAttributesType)`
  `WindowAttributesType& operator&=(WindowAttributesType&, WindowAttributesType)`
  `WindowAttributesType& operator^=(WindowAttributesType&, WindowAttributesType)`

Enumerator
WA_TITLE | Honor the title field.
WA_X | Honor the X coordinate field.
WA_Y | Honor the Y coordinate field.
WA_CURSOR | Honor the cursor field.
WA_VISUAL | Honor the visual field.
WA_WMCLASS | Honor the wmclass_class and wmclass_name fields.
WA_NOREDIR | Honor the override_redirect field.
WA_TYPE_HINT | Honor the type_hint field.

## ◆ WindowEdge

enum Gdk::WindowEdge

Determines a window edge or corner.

Enumerator

WINDOW_EDGE_WEST | The left edge.
WINDOW_EDGE_EAST | The right edge.
WINDOW_EDGE_SOUTH_WEST | The lower left corner.
WINDOW_EDGE_SOUTH | The lower edge.
WINDOW_EDGE_SOUTH_EAST | The lower right corner.

## ◆ WindowHints

enum Gdk::WindowHints

Used to indicate which fields of a Gdk::Geometry struct should be paid attention to.

Also, the presence/absence of GDK_HINT_POS, GDK_HINT_USER_POS, and GDK_HINT_USER_SIZE is significant, though they don't directly refer to Gdk::Geometry fields. GDK_HINT_USER_POS will be set automatically by Gtk::Window if you call gtk_window_move(). GDK_HINT_USER_POS and GDK_HINT_USER_SIZE should be set if the user specified a size/position using a –geometry command-line argument; gtk_window_parse_geometry() automatically sets these flags.

Bitwise operators:
  `WindowHints operator|(WindowHints, WindowHints)`
  `WindowHints operator&(WindowHints, WindowHints)`
  `WindowHints operator^(WindowHints, WindowHints)`
  `WindowHints operator~(WindowHints)`
  `WindowHints& operator|=(WindowHints&, WindowHints)`
  `WindowHints& operator&=(WindowHints&, WindowHints)`
  `WindowHints& operator^=(WindowHints&, WindowHints)`

Enumerator
HINT_POS | Indicates that the program has positioned the window.
HINT_MIN_SIZE | Min size fields are set.
HINT_MAX_SIZE | Max size fields are set.
HINT_BASE_SIZE | Base size fields are set.
HINT_ASPECT | Aspect ratio fields are set.
HINT_RESIZE_INC | Resize increment fields are set.
HINT_WIN_GRAVITY | Window gravity field is set.
HINT_USER_POS | Indicates that the window’s position was explicitly set by the user.
HINT_USER_SIZE | Indicates that the window’s size was explicitly set by the user.

## ◆ WindowState

enum Gdk::WindowState

Specifies the state of a toplevel window.

Bitwise operators:
  `WindowState operator|(WindowState, WindowState)`
  `WindowState operator&(WindowState, WindowState)`
  `WindowState operator^(WindowState, WindowState)`
  `WindowState operator~(WindowState)`
  `WindowState& operator|=(WindowState&, WindowState)`
  `WindowState& operator&=(WindowState&, WindowState)`
  `WindowState& operator^=(WindowState&, WindowState)`
