Gdk Namespace Reference


Classes

struct  AtomStringTraits
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
class  PixbufAnimationIter
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.
