ToolboxBitmapAttribute

ToolboxBitmapAttribute

---

System.Drawing (system.drawing.dll)

class

This Attribute class is something of a refugee from the System.Drawing.Design namespace. If you apply the attribute to a component and specify either the filename of a 16 x 16 bitmap, or a component type (e.g., typeof(SomeOtherComponent) ), the appropriate image (either your bitmap or the image specified for the other type) will be displayed in the designer toolbox next to your component's name .

You can also specify both, and it will fallback on the type imagery if the bitmap file doesn't exist.

This is, of course, extremely useful; but what it is doing in this namespace is a mystery.

 public class  ToolboxBitmapAttribute  : Attribute {  // Public Constructors  public  ToolboxBitmapAttribute  (string  imageFile  );    public  ToolboxBitmapAttribute  (Type  t  );    public  ToolboxBitmapAttribute  (Type  t  , string  name  );  // Public Static Fields  public static readonly ToolboxBitmapAttribute  Default  ;  // =System.Drawing.ToolboxBitmapAttribute   // Public Static Methods  public static Image  GetImageFromResource  (Type  t  , string  imageName  , bool  large  );  // Public Instance Methods  public override bool  Equals  (object  value  );  // overrides Attribute  public override int  GetHashCode  ();  // overrides Attribute  public Image  GetImage  (object  component  );    public Image  GetImage  (object  component  , bool  large  );    public Image  GetImage  (Type  type  );    public Image  GetImage  (Type  type  , bool  large  );    public Image  GetImage  (Type  type  , string  imgName  , bool  large  ); }
