ShapeContainer.GetNextShape Method (Shape, Boolean)

 

Retrieves the next or previous shape in the order of the ShapeCollection.

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

Syntax

public Shape GetNextShape(
    Shape shape,
    bool forward
)
public:
Shape^ GetNextShape(
    Shape^ shape,
    bool forward
)
member GetNextShape : 
        shape:Shape *
        forward:bool -> Shape
Public Function GetNextShape (
    shape As Shape,
    forward As Boolean
) As Shape

Parameters

  • forward
    Type: System.Boolean

    true to search forward; false to search backward.

Return Value

Type: Microsoft.VisualBasic.PowerPacks.Shape

The next Shape in the order of the ShapeCollection.

Remarks

The initial order is determined by the order in which shapes are added to the ShapeCollection; you can change the order by calling the SetChildIndex method.

Examples

The following example demonstrates how to use the GetNextShape and SelectNextShape methods to use the TAB key to move through the shapes on a form. This example requires that you have at least three RectangleShape controls on a form.

private void Shapes_PreviewKeyDown(object sender, 
    System.Windows.Forms.PreviewKeyDownEventArgs e)
{
    Shape sh;
    // Check for the TAB key.
    if (e.KeyCode==Keys.Tab)
        // Find the next shape in the order.
    {
        sh = shapeContainer1.GetNextShape((Shape) sender, true);
        // Select the next shape.
        shapeContainer1.SelectNextShape((Shape) sender, true, true);
    }
}
Private Sub Shapes_PreviewKeyDown(
    ByVal sender As Object, 
    ByVal e As System.Windows.Forms.PreviewKeyDownEventArgs
  ) Handles RectangleShape1.PreviewKeyDown, 
            RectangleShape2.PreviewKeyDown, 
            RectangleShape3.PreviewKeyDown

    Dim sh As Shape
    ' Check for the TAB key.
    If e.KeyCode = Keys.Tab Then
        ' Find the next shape in the order.
        sh = ShapeContainer1.GetNextShape(sender, True)
        ' Select the next shape.
        ShapeContainer1.SelectNextShape(sender, True, True)
    End If
End Sub
