gdk-sharp 2.8.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details.

Describes an allocated or unallocated color.

The Gdk.Color structure is used to describe an allocated or unallocated color. Unallocated colors only have the red, green and blue ushort values initialized. Colors are allocated using the method. After a color is allocated the value in the field is valid.


	  DrawRedLine (Gdk.Drawable drawable)
	  {
	  	Gdk.GC gc = new Gdk.GC (drawable);
	  
	  	Gdk.Color red_color = new Gdk.Color (0xff, 0, 0);
	  
		  // Use the system colormap, easy.
		  Gdk.Colormap colormap = Gdk.Colormap.System;
		  
		  colormap.AllocColor (red_color, true, true);
	
	          gc.Foreground = red_color;
	  
		  // Now you can use it
		  drawable.DrawLine (gc, 0, 0, 100, 100);
	  }

System.ValueType Field Gdk.Color

Unallocated, empty color.

Constructor

Color constructor from RGB byte values

Red value (0-255) Green value (0-255) Blue value (0-255) This constructs the color from three byte values for red, green and blue. Notice that the Gdk.Color structure actually uses 16-bit color values, so the byte values are mapped into the 16-bit value space. This is just a convenience routine to initialize this structure. To use the Gdk.Color you must allocate it within the current colormap.


	      DrawRedLine (Gdk.Drawable drawable)
	      {
	              Gdk.GC gc = new Gdk.GC (drawable);
	              
	              Gdk.Color red_color = new Gdk.Color (0xff, 0, 0);
	              
	              // Use the system colormap, easy.
	              Gdk.Colormap colormap = Gdk.Colormap.System;
	              
	              colormap.AllocColor (red_color, true, true);
	              
	              // Now you can use it
	              drawable.DrawLine (gc, 0, 0, 100, 100);
              }

Method Gdk.Color

Creates a color from an unmanaged location.

A pointer to the unmanaged GdkColor structure. This returns a Gdk.Color structure. The parameter points to a C-based GdkColor structure. This routine creates a Gdk.Color structure from its unmanaged version. Method System.Boolean

Compares whether two colors are equal.

The color to compare true if the red, green and blue components are the same Notice that this will not compare the value, it will only compare the red, green and blue elements. Property GLib.GType

The GLib.GType for Gdk.Color

a The GLib.GType for the Gdk.Color class. Field System.UInt32

Pixel value for the color.

Colors are specified in Gdk by their red, green and blue elements. But before the color can be used, the color has to be allocated in a given colormap. The value of the allocation is stored in this pixel field and it is the token used to render the color. The pixel value is initialized when using the method. Field System.UInt16

Red element of the color.

Field System.UInt16

Green element of the color.

Field System.UInt16

Blue element of the color.
