项目
10/25/2012

初始化 LineShape 类的新实例，指定它将父节点的 ShapeContainer 。

命名空间： Microsoft.VisualBasic.PowerPacks
程序集： Microsoft.VisualBasic.PowerPacks.Vs（在 Microsoft.VisualBasic.PowerPacks.Vs.dll 中）

语法

声明
Public Sub New ( _
    parent As ShapeContainer _
)

public LineShape(
    ShapeContainer parent
)

public:
LineShape(
    ShapeContainer^ parent
)

new : 
        parent:ShapeContainer -> LineShape

public function LineShape(
    parent : ShapeContainer
)

参数

parent
类型：Microsoft.VisualBasic.PowerPacks.ShapeContainer
形状将父节点的 ShapeContainer

备注

LineShape 直接在窗体或容器控件无法显示;在 ShapeContainer 对象必须承载它。在初始化 LineShape后，必须将其 Parent 属性设置为现有 ShapeContainer 或到 ShapeContainer的新实例。

示例

下面的示例初始化 ShapeContainer 和 LineShape，设置 LineShape 的 Parent 属性设置为 ShapeContainer，并显示一行对角线。

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(0, 0)
line1.EndPoint = New System.Drawing.Point(1000, 1000)

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(0, 0);
line1.EndPoint = new System.Drawing.Point(1000, 1000);
