For example, Color.Red represents the color red. It has a static property for every possible color. We create a SolidBrush object by calling its constructor and passing a Color structure as the only parameter. For instance, the Brushes.Pink, Brushes.Red, and Brushes.Green members represent Brush objects with the colors pink, red, and green, respectively.Ī solid brush is a brush that fills an area with a single solid color. Brushes provides more than 140 static members (properties), and each of these members represents a brush with a particular color (including all the standard colors). The Brushes class is a sealed class (it cannot be inherited). Figure 4.2 shows the brush types and their classes.įigure 4.2. GDI+ provides four different kinds of brushes: solid, hatch, texture, and gradient. Classes inherited from the Brush classĪpplications generally call fill methods of the appropriate Graphics class, which in turn use brushes to fill GDI+ objects (such as an ellipse, an arc, or a polygon) with a certain kind of brush. Figure 4.1 shows all the Brush-derived classes that can be used in your GDI+ applications.įigure 4.1. All usable classes are inherited from the abstract Brush class. NET Framework library, the Brush class is an abstract base class, which means you cannot create an instance of it without using its derived classes. SolidBrush redBrush = new SolidBrush(Color.Red) The last line disposes of the SolidBrush object. The first line gets the Graphics object of the form, and the second line creates a brush using the SolidBrush class, which later is used to fill a rectangle. This code is written on a form's paint event handler. The code snippet in Listing 4.1 creates a red SolidBrush object and uses it to draw a rectangle. Alternatively, you can use the namespace as a prefix to the class for example, represents the Brush class if you do not wish to include the System.Drawing namespace in your application. For example, the Brush, SolidBrush, TextureBrush, and Brushes classes are defined in the System.Drawing namespace and the HatchBrush and GradientBrush classes are defined in the 2D namespace.īefore using brushes, obviously you must include the corresponding namespace to your application. The System.Drawing namespace defines general brush-related classes and functionality, and the 2D namespace defines advanced 2D brush-related functionality. NET Framework library, brush-related functionality is defined in two namespaces: System.Drawing and 2D.
