Classes

class  Gdk::Bitmap
 Bitmaps are simply pixmaps with a depth of 1. More...
class  Gdk::Color
 Gdk::Color is used to describe an allocated or unallocated color. More...
class  Gdk::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  Gdk::Cursor
 This represents a cursor. More...
class  Gdk::Device
 A Gdk::Device instance contains a detailed description of an extended input device. More...
class  Gdk::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  Gdk::DisplayManager
 The purpose of the GdkDisplayManager singleton object is to offer notification when displays appear or disappear or the default display changes. More...
class  Gdk::DragContext
 A Gdk::DragContext holds information about a drag in progress. More...
class  Gdk::Drawable
 Drawing Primitives. More...
class  Gdk::Event
class  Gdk::GC
 All drawing operations in GDK take a graphics context (GC) argument. More...
class  Gdk::Image
 This represents an area for drawing graphics. More...

class  Gdk::PixbufAnimationIter
class  Gdk::PixbufFormat
class  Gdk::PixbufLoader
class  Gdk::Pixmap
 Pixmaps are offscreen drawables. More...
class  Gdk::Rectangle
 Gdk::Rectangle is a structure holding the position and size of a rectangle. More...
class  Gdk::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  Gdk::RgbCmap
class  Gdk::Screen
 Object representing a physical screen Gdk::Screen objects are the GDK representation of a physical screen. More...
class  Gdk::Point
 This is a simple structure containing an x and y coordinate of a point. More...
struct  Gdk::AtomStringTraits
class  Gdk::Visual
 A Gdk::Visual describes a particular video hardware display format. More...
class  Gdk::Window
 A Gdk::Window is a rectangular region on the screen. More...

Function Documentation

void flush (  ) 
 

bool 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> 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> 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.
