ShapeContainer Constructor

Initializes a new instance of the ShapeContainer class.

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

Syntax

'Declaration
Public Sub New

public ShapeContainer()

public:
ShapeContainer()

new : unit -> ShapeContainer

public function ShapeContainer()

Remarks

When you create a line or shape at run time by using the New method, its Parent property must be set to a ShapeContainer. If a ShapeContainer already exists for the form or container, you should set the Parent property to that ShapeContainer. If no ShapeContainer exists, you can create a ShapeContainer by using the New method and set its Parent property to the form or container.

Examples

The following example checks for an existing ShapeContainer and sets the Parent property of an OvalShape control created at run time by using the New method.

Private Sub Form1_Load() Handles MyBase.Load
    Dim NewOval As New OvalShape
    Dim i As Integer 
    Dim found As Boolean 
    ' Loop through the Controls collection. 
    For i = 0 To Me.Controls.Count - 1
        ' If a ShapeContainer is found, make it the parent. 
        If TypeOf Controls.Item(i) Is ShapeContainer Then
            NewOval.Parent = Controls.Item(i)
            found = True 
            Exit For 
        End If 
    Next 
    ' If no ShapeContainer is found, create one and set the parents. 
    If found = False Then 
        Dim sc As New ShapeContainer
        sc.Parent = Me
        NewOval.Parent = sc
    End If
    NewOval.Size = New Size(200, 300)
End Sub

private void form1_Load(System.Object sender, System.EventArgs e)
{
    OvalShape NewOval = new OvalShape();
    int i;
    bool found = false;
    // Loop through the Controls collection. 
    for (i = 0; i < this.Controls.Count; i++)
    {
        // If a ShapeContainer is found, make it the parent. 
        if (this.Controls[i] is ShapeContainer)
        {
            NewOval.Parent = ((ShapeContainer)this.Controls[i]);
            found = true;
            break;
        }
    }
    // If no ShapeContainer is found, create one and set the parents. 
    if (found == false)
    {
        ShapeContainer sc = new ShapeContainer();
        sc.Parent = this;
        NewOval.Parent = sc;
    }
    NewOval.Size = new Size(200, 300);
}
