## Classes
class | Bitmap
| Bitmaps are simply pixmaps with a depth of 1. More...
class | Color
| Gdk::Color is used to describe an allocated or unallocated color. More...
class | Colormap
| A Colormap is an object that contains the mapping between the color values stored in memory and the RGB values that are used to display color values. More...
class | Cursor
| This represents a cursor. More...
class | Device
| A Gdk::Device instance contains a detailed description of an extended input device. More...
class | Display
| Gdk::Display object's purpose is two fold: To grab/ungrab keyboard focus and mouse pointer To manage and provide information about the Gdk::Screen(s) available for this Gdk::Display. More...
class | DisplayManager
| The purpose of the GdkDisplayManager singleton object is to offer notification when displays appear or disappear or the default display changes. More...
class | DragContext
| A Gdk::DragContext holds information about a drag in progress. More...
class | Drawable
| Drawing Primitives. More...
class | Event
class | GC
| All drawing operations in GDK take a graphics context (GC) argument. More...
class | Image
| This represents an area for drawing graphics. More...
class | Pixbuf
class | PixbufAnimation
| The gdk-pixbuf library provides a simple mechanism to load and represent animations. More...
class | PixbufAnimationIter
| An iterator which points to a certain position in a PixbufAnimation. More...
class | PixbufError
| Exception class for Gdk::Pixbuf errors. More...
class | PixbufFormat
class | PixbufLoader
class | Pixmap
| Pixmaps are offscreen drawables. More...
class | Point
| This is a simple structure containing an x and y coordinate of a point. More...
class | Rectangle
| Gdk::Rectangle is a structure holding the position and size of a rectangle. More...
class | Region
| This is an opaque data type holding a set of arbitrary pixels, and is usually used for clipping graphical operations (see Gdk::GC::set_clip_region()). More...
class | RgbCmap
class | Screen
| Object representing a physical screen Gdk::Screen objects are the GDK representation of a physical screen. More...
class | Visual
| A Gdk::Visual describes a particular video hardware display format. More...
class | Window
| A Gdk::Window is a rectangular region on the screen. More...

## Function Documentation

void Gdk::flush | ( |  | ) |

bool Gdk::rgb_ditherable | ( |  | ) |

Determines whether the visual is ditherable.

This function may be useful for presenting a user interface choice to the user about which dither mode is desired; if the display is not ditherable, it may make sense to gray out or hide the corresponding UI widget. result true if the visual is ditherable.

Glib::RefPtr<Colormap> Gdk::rgb_get_colormap | ( |  | ) |

Get the preferred colormap for rendering image data.

Not a very useful function; historically, GDK could only render RGB image data to one colormap and visual, but in the current version it can render to any colormap and visual. So there's no need to call this function.

Returns
  The preferred colormap

Glib::RefPtr<Visual> Gdk::rgb_get_visual | ( |  | ) |

Gets a "preferred visual" chosen by GdkRGB for rendering image data on the default screen.

In previous versions of GDK, this was the only visual GdkRGB could use for rendering. In current versions, it's simply the visual GdkRGB would have chosen as the optimal one in those previous versions. GdkRGB can now render to drawables with any visual.

Returns
  The Gdk::Visual chosen by GdkRGB.

int Gdk::screen_height | ( |  | ) |

int Gdk::screen_height_mm | ( |  | ) |

int Gdk::screen_width | ( |  | ) |

int Gdk::screen_width_mm | ( |  | ) |
