重画系列:双色Button (转)

重画系列:双色Button (转)[@more@]

效果如下图:

比较简单,下面是源代码,新建一类库工程,拷贝以下源代码覆盖Class1,生成Dll文件就可以使用了

Public Class XpStyleButton
  Inherits System.windows.Forms.UserControl

#Region " Windows 窗体设计器生成的代码 "

  Public Sub New()
  MyBase.New()

  '该调用是 Windows 窗体设计器所必需的。
  InitializeComponent()

  '在 InitializeComponent() 调用之后添加任何初始化
  setstyle(ControlStyles.AllPaintingInWmPaint Or ControlStyles.DoubleBuffer Or ControlStyles.UserPaint, True)
  End Sub

  'UserControl1 重写 dispose 以清理组件列表。
  Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
  If disposing Then
  If Not (components Is Nothing) Then
  components.Dispose()
  End If
  End If
  MyBase.Dispose(disposing)
  End Sub

  'Windows 窗体设计器所必需的
  Private components As System.ComponentModel.IContainer

  '注意：以下过程是 Windows 窗体设计器所必需的
  '可以使用 Windows 窗体设计器修改此过程。
  '不要使用代码编辑器修改它。
  buggerStepThrough()> Private Sub InitializeComponent()
  '
  'XpStyleButton
  '
  Me.Name = "XpStyleButton"
  Me.Size = New System.Drawing.Size(264, 88)

  End Sub

#End Region

以下是测试的源代码,需要添加上面生成的Dll的引用:

Public Class Form1
  Inherits System.Windows.Forms.Form

#Region " Windows 窗体设计器生成的代码 "

  Public Sub New()
  MyBase.New()

  '该调用是 Windows 窗体设计器所必需的。
  InitializeComponent()

  '在 InitializeComponent() 调用之后添加任何初始化

  End Sub

  '窗体重写处置以清理组件列表。
  Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
  If disposing Then
  If Not (components Is Nothing) Then
  components.Dispose()
  End If
  End If
  MyBase.Dispose(disposing)
  End Sub
  Private button1 As XPStyleButton.XpStyleButton
  'Windows 窗体设计器所必需的
  Private components As System.ComponentModel.IContainer

  '注意：以下过程是 Windows 窗体设计器所必需的
  '可以使用 Windows 窗体设计器修改此过程。
  '不要使用代码编辑器修改它。
  Friend WithEvents XpStyleButton1 As XPStyleButton.XpStyleButton
  Friend WithEvents XpStyleButton4 As XPStyleButton.XpStyleButton
  Private Sub InitializeComponent()
  Me.button1 = New XPStyleButton.XpStyleButton()
  Me.XpStyleButton1 = New XPStyleButton.XpStyleButton()
  Me.XpStyleButton4 = New XPStyleButton.XpStyleButton()
  Me.SuspendLayout()
  '
  'button1
  '
  Me.button1.BackColor = System.Drawing.SystemColors.Control
  Me.button1.ButtonStyle = XPStyleButton.XpStyleButton.Style.RectStyle
  Me.button1.ForeColor = System.Drawing.Color.White

  Me.XpStyleButton4.Name = "XpStyleButton4"
  Me.XpStyleButton4.Size = New System.Drawing.Size(96, 96)
  Me.XpStyleButton4.TabIndex = 2
  '
  'Form1
  '
  Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)
  Me.ClientSize = New System.Drawing.Size(520, 273)
  Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.button1, Me.XpStyleButton4, Me.XpStyleButton1})
  Me.Name = "Form1"
  Me.Text = "Form1"
  Me.ResumeLayout(False)

  End Sub

#End Region
