Remarks
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.
Examples
The following example creates a ShapeContainer and a RectangleShape, adds them to a form, and displays a rectangle.
Private Sub DrawRectangle()
Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
Dim rect1 As New Microsoft.VisualBasic.PowerPacks.RectangleShape
' Set the form as the parent of the ShapeContainer.
canvas.Parent = Me
' 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
End Sub
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;
}
