Describes a particular video hardware display format.

A Gdk.Visual 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. For example, a piece of display hardware might support 24-bit color, 16-bit color, or 8-bit color; meaning 24/16/8-bit pixel sizes. For a given pixel size, pixels can be in different formats; for example the "red" element of an RGB pixel may be in the top 8 bits of the pixel, or may be in the lower 4 bits. Usually you can avoid thinking about visuals in GTK+. Visuals are useful to interpret the contents of a , but you should avoid GdkImage precisely because its contents depend on the display hardware; use instead, for all but the most low-level purposes. Also, anytime you provide a , the visual is implied as part of the colormap (), so you won't have to provide a visual in addition. There are several standard visuals. The visual returned by is the system's default visual. return the visual most suited to displaying full-color image data. If you use the calls in , you should create your windows using this visual (and the colormap returned by ). A number of functions are provided for determining the "best" available visual. For the purposes of making this determination, higher bit depths are considered better, and for visuals of the same bit depth, is preferred at 8bpp, otherwise, the visual types are ranked in the order of (highest to lowest) , , , , then . GLib.Object GLib.IWrapper System.IDisposable Method Gdk.Visual

Get the best visual with depth depth for the default GDK screen.

A bit depth Best visual for the given depth. Get the best visual with depth depth for the default GDK screen. Color visuals and visuals with mutable colormaps are preferred over grayscale or fixed-colormap visuals. The return value should not be freed. may be returned if no visual supports . Method Gdk.Visual

Get the best visual of the given visual_type for the default GDK screen.

Required visual type. Best visual of the given type Get the best visual of the given for the default GDK screen. Visuals with higher color depths are considered better. The return value should not be freed. may be returned if no visual has type . Method Gdk.Visual

Get the best visual given a visual type and a required depth.

Required depth. Required visual type. Best visual of the given type and depth. Get the best visual of the given at the given for the default GDK screen. Visuals with higher color depths are considered better. The return value should not be freed. may be returned if no visual that match the type and . Method System.Void

Disposes the resources associated with the object.

Constructor

Internal constructor

Pointer to the C object. An instance of Visual, wrapping the C object. This is an internal constructor, and should not be used by user code. Constructor

To be added

To be added: an object of type 'Gdk.Visual' To be added Property System.UInt32

The GLib Type for Gdk.Visual

The GLib Type for the Gdk.Visual class. Property Gdk.VisualType

Best visual type for the default Gdk screen

The best visual type available. Return the best available visual type for the default GDK screen. Property System.Int32

Best depth for the default Gdk screen.

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

Visual with the most available colors for the default GDK screen.

The best visual. Get the visual with the most available colors for the default GDK screen. Property Gdk.Visual

The system'sdefault visual for the default GDK screen.

The system visual Get the system'sdefault visual for the default GDK screen. This is the visual for the root window of the display. Constructor

Internal constructor

GLib type for the type Creates a new instance of Visual, using the GLib-provided type This is a constructor used by derivative types of that would have their own GLib type assigned to it. This is not typically used by C# code.
