OvalShape Constructor

Initializes a new instance of the OvalShape class.

Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

'宣告
Public Sub New

public OvalShape()

public:
OvalShape()

new : unit -> OvalShape

public function OvalShape()

Remarks

An OvalShape control cannot be displayed directly on a form or container control; it must be contained in a ShapeContainer object. After you initialize an OvalShape, you will have to set its Parent property either to an existing ShapeContainer or to a new instance of ShapeContainer.

Examples

The following example creates a ShapeContainer and an OvalShape, adds them to a form, and displays a circle.

Private Sub DrawCircle()
    Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
    Dim oval1 As New Microsoft.VisualBasic.PowerPacks.OvalShape
    ' Set the form as the parent of the ShapeContainer.
    canvas.Parent = Me
    ' Set the ShapeContainer as the parent of the OvalShape.
    oval1.Parent = canvas
    ' Set the location and size of the circle.
    oval1.Left = 10
    oval1.Top = 10
    oval1.Width = 100
    oval1.Height = 100
End Sub

private void DrawCircle1()
{
    Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas = 
        new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
    Microsoft.VisualBasic.PowerPacks.OvalShape oval1 = 
        new Microsoft.VisualBasic.PowerPacks.OvalShape();
    // Set the form as the parent of the ShapeContainer.
    canvas.Parent = this;
    // Set the ShapeContainer as the parent of the OvalShape.
    oval1.Parent = canvas;
    // Set the location and size of the circle.
    oval1.Left = 10;
    oval1.Top = 10;
    oval1.Width = 100;
    oval1.Height = 100;
}
