RectangleShape Class

The RectangleShape control enables you to draw rectangles on a form or container at design time or run time.

When you add a Line or Shape control to a form or container, an invisible ShapeContainer object is created. The ShapeContainer acts as a drawing surface for the shapes within each container control. Each ShapeContainer has a corresponding ShapeCollection that enables you to iterate through the Line and Shape controls that are contained in the ShapeContainer.

When you create a RectangleShape control at run time, you must also create a ShapeContainer and set the Parent property of the RectangleShape to the ShapeContainer.

The following example creates a ShapeContainer and a RectangleShape, adds them to a form, and displays a rectangle.

private void DrawRectangle()
{
    Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas = 
        new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
    Microsoft.VisualBasic.PowerPacks.RectangleShape rect1 = 
        new Microsoft.VisualBasic.PowerPacks.RectangleShape();
    // Set the form as the parent of the ShapeContainer.
    canvas.Parent = this;
    // Set the ShapeContainer as the parent of the RectangleShape.
    rect1.Parent = canvas;
    // Set the location and size of the rectangle.
    rect1.Left = 10;
    rect1.Top = 10;
    rect1.Width = 300;
    rect1.Height = 100;
}
