Class Visual

public class Visual extends GObject

Describes a particular video hardware display format. It includes information about the number of bits used for each color, the way the bits are translated into an RGB value for display, and the way the bits are stored in memory.

static Visual	getVisual(int depth, VisualType vt) Combines getVisual(int depth) and getVisual(VisualType vt).

Method Detail

getBestDepth

public static int getBestDepth()

Get the best available depth for the default GDK display. "Best" means "largest," i.e. 32 preferred over 24 preferred over 8 bits per pixel.

getBestVisualType

public static VisualType getBestVisualType()

Return the best available visual type (the one with the most colors) for the default GDK display.

getBitsPerRGB

public int getBitsPerRGB()

getBlueMask

public int getBlueMask()

getBluePrec

public int getBluePrec()

getBlueShift

public int getBlueShift()

getByteOrder

public ByteOrder getByteOrder()

getColormapSize

public int getColormapSize()

getDepth

public int getDepth()

getGreenMask

public int getGreenMask()

getGreenPrec

public int getGreenPrec()

getGreenShift

public int getGreenShift()

getRedMask

public int getRedMask()

getRedPrec

public int getRedPrec()

getRedShift

public int getRedShift()

getScreen

public Screen getScreen()

getSystemVisual

public static Visual getSystemVisual()

Get the default or system visual for the default GDK display. This is the visual for the root window of the display.

getVisual

public static Visual getVisual()

Get the visual with the most available colors for the default GDK display.

getVisual

public static Visual getVisual(int depth)

Get the best visual with depth depth for the default GDK display. Color visuals and visuals with mutable colormaps are preferred over grayscale or fixed-colormap visuals. NULL may be returned if no visual supports depth.

getVisual

public static Visual getVisual(VisualType vt)

Get the best visual of the given visual_type for the default GDK display. Visuals with higher color depths are considered better. NULL may be returned if no visual has type visual_type.

getVisual

public static Visual getVisual(int depth, VisualType vt)

Combines getVisual(int depth) and getVisual(VisualType vt).
