LineShape Class
Represents a control displayed as a horizontal, vertical, or diagonal line.
Namespace: Microsoft.VisualBasic.PowerPacks
Assembly: Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)
Syntax
'Declaration
<ToolboxBitmapAttribute(GetType(LineShape), "Microsoft.VisualBasic.PowerPacks.LineShape.bmp")> _
Public Class LineShape _
Inherits Shape
'Usage
Dim instance As LineShape
[ToolboxBitmapAttribute(typeof(LineShape), "Microsoft.VisualBasic.PowerPacks.LineShape.bmp")]
public class LineShape : Shape
[ToolboxBitmapAttribute(typeof(LineShape), L"Microsoft.VisualBasic.PowerPacks.LineShape.bmp")]
public ref class LineShape : public Shape
public class LineShape extends Shape
Remarks
The LineShape control enables you to draw lines 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.
When you create a LineShape control at run time, you must also create a ShapeContainer and set the Parent property of the LineShape to the ShapeContainer.
Examples
The following example creates a ShapeContainer and a LineShape, adds them to a form, and displays a vertical line from the top to the bottom of the form.
Dim canvas As New Microsoft.VisualBasic.PowerPacks.ShapeContainer
Dim line1 As New Microsoft.VisualBasic.PowerPacks.LineShape
' Set the form as the parent of the ShapeContainer.
canvas.Parent = Me
' Set the ShapeContainer as the parent of the LineShape.
line1.Parent = canvas
' Set the starting and ending coordinates for the line.
line1.StartPoint = New System.Drawing.Point(Me.Width / 2, 0)
line1.EndPoint = New System.Drawing.Point(Me.Width / 2, Me.Height)
Microsoft.VisualBasic.PowerPacks.ShapeContainer canvas =
new Microsoft.VisualBasic.PowerPacks.ShapeContainer();
Microsoft.VisualBasic.PowerPacks.LineShape line1 =
new Microsoft.VisualBasic.PowerPacks.LineShape();
// Set the form as the parent of the ShapeContainer.
canvas.Parent = this;
// Set the ShapeContainer as the parent of the LineShape.
line1.Parent = canvas;
// Set the starting and ending coordinates for the line.
line1.StartPoint = new System.Drawing.Point(this.Width / 2, 0);
line1.EndPoint = new System.Drawing.Point(this.Width / 2, this.Height);
