VB.NET中怎么制作一個圖片按鈕,相信很多沒有經驗的人對此束手無策,為此本文總結了問題出現的原因和解決方法,通過這篇文章希望你能解決這個問題。
VB.NET制作圖片按鈕思路:很簡單,就是在一個picturebox控件上放置一個button控件,然后將這個button添加進picturebox上(確保先拖拽picturebox,后拖拽button),設置這個button的背景色(這個時候是相對于picturebox)為透明。
Imports System.ComponentModel Public Class picturebutton Inherits System.Windows.Forms.UserControl #Region " Windows 窗體設計器生成的代碼 " 'UserControl 重寫 dispose 以清理組件列表。 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 窗體設計器所必需的 Private components As System.ComponentModel.IContainer
注意:以下VB.NET制作圖片按鈕的過程是 Windows 窗體設計器所必需的
可以使用 Windows 窗體設計器修改此過程。
不要使用代碼編輯器修改它。
Friend WithEvents PictureBox1 As System.Windows.Forms.PictureBox
Friend WithEvents Button1 As System.Windows.Forms.Button
<System.Diagnostics.DebuggerStepThrough()>
Private Sub InitializeComponent()Me.PictureBox1 = New System.Windows.Forms.PictureBox()
Me.Button1 = New System.Windows.Forms.Button()
Me.SuspendLayout()
'PictureBox1
Me.PictureBox1.Name = "PictureBox1"
Me.PictureBox1.Size = New System.Drawing.Size(136, 40)
Me.PictureBox1.TabIndex = 0
Me.PictureBox1.TabStop = False
'Button1
Me.Button1.Name = "Button1"
Me.Button1.TabIndex = 1
Me.Button1.Text = "Button1"
'picturebutton
Me.Controls.AddRange(New System.Windows.Forms.Control()
{Me.Button1, Me.PictureBox1})Me.Name = "picturebutton"
Me.ResumeLayout(False)
End Sub
#End Region
Public Sub New()
MyBase.New()
該調用是 Windows 窗體設計器所必需的。
InitializeComponent() '在 InitializeComponent() 調用之后添加任何初始化 Me.Button1.Width = 100 ‘設置按鈕的初始大小 Me.Button1.Height = 23 Me.Button1.BackColor = Color.Transparent ‘背景色透明 Me.Button1.ForeColor = Color.Black Me.PictureBox1.Controls.Add(Me.Button1) End Sub Private m_text As String ‘設置按鈕標題 Private a As Integer 'Private m_image As Image <Description("picturebox圖片。")> _ Public Property image() As image Get Return Me.PictureBox1.Image End Get Set(ByVal Value As image) Me.PictureBox1.Image = Value Invalidate() End Set End Property Shadows Property forecolor() As Color Get Return Me.Button1.ForeColor End Get Set(ByVal Value As Color) Me.Button1.ForeColor = Value Invalidate() End Set End Property Shadows Sub ResetForeColor() Me.Button1.ForeColor = SystemColors.ControlText End Sub
VB.NET制作圖片按鈕的單擊事件
Event BtnClick(ByVal sender As Object, ByVal e As System.EventArgs)
Private Sub Button1_Click(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Button1.ClickRaiseEvent BtnClick(Me, e)
End Sub
控件改變大小時,需重繪控件,以使子控件排位美觀
Private Sub FileTextBox_Resize(ByVal sender As Object,
ByVal e As System.EventArgs) Handles MyBase.ResizeRedrawControls()
End Sub
子控件會自動繼續容器的Font屬性,所以改變容器的Font屬性時也要重繪控件
Protected Overrides Sub OnFontChanged(ByVal e As System.EventArgs) '讓基控件更新文本框 MyBase.OnFontChanged(e) '重繪控件 RedrawControls() End Sub '重繪控件 Private Sub RedrawControls() '控件寬度 Dim width As Integer = Me.ClientRectangle.Width '獲得工作區寬
以VB.NET制作圖片按鈕的高度來確定控件高度
Dim btnSide As Integer = Button1.Height Dim btnwidth As Integer = Button1.Width If Me.ClientRectangle.Height <> btnSide Then
設置控件工作區的大小
'Me.SetClientSizeCore(btnwidth, btnSide)
Me.SetClientSizeCore(width, btnSide)
'這里使用工作區的寬是因為:按鈕和picturebox可以調整寬度
'上面的語句激發了嵌套的Resize事件,因此需要立即退出,
如果不退出,就會反復調用進入死循環Exit Sub
End If
調整子控件的大小
'Txt.SetBounds(0, 0, width, btnSide)
'Btn.SetBounds(width - 19, 2, 17, btnSide - 4)
Me.PictureBox1.SetBounds(0, 0, width, btnSide)
Me.PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage
Me.Button1.SetBounds(0, 0, width, btnSide)
End Sub
End Class
