Question

当我的TabControls中添加了一个新的TabPage时，我希望它自动调整为Form1的当前高度/宽度。我可以在Form Load上执行此操作。但是，当我添加一个新选项卡然后调整窗口大小时，它什么都不做。感谢您提供任何有用的意见。

导入System.IO 公共类Form1

'The Global Variables
Dim theControls As New theControls


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'For Auto Sizing theControls to Form1
    TabPage1.Controls.Add(theControls)

    theControls.theBrowser.Navigate("http://google.com")
End Sub

Private Sub Form1_SizeChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.SizeChanged


    'For Auto Sizing theControls to Form1

    Me.TabControl1.Width = Me.Width - 20
    Me.TabControl1.Height = Me.Height
    theControls.Width = Me.TabControl1.Width - 20
    theControls.Height = Me.TabControl1.Height - 20



End Sub

Private Sub TabControl1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabControl1.Click

    'Add new tab with the same controls.
    Dim theNewTab As New TabPage
    Dim theOtherControls As New theControls
    Dim theTabCounter As Integer = TabControl1.TabPages.Count


    Dim theSelectedTab As String = TabControl1.SelectedTab.Text

    If theSelectedTab = "+" Then
        TabControl1.TabPages.Insert(theTabCounter - 1, theNewTab)
        theNewTab.Controls.Add(theOtherControls)

        theControls.theBrowser.Navigate("http://google.com")
        theOtherControls.theBrowser.Navigate("http://google.com")
        TabControl1.SelectTab(theTabCounter - 1)
    End If
End Sub

结束班

tabPageCounter变量可以忽略。我开始认为需要For Each循环，但我认为这是一种更简单的方法。从我在网上找到的，我已经得到了这个Dock功能，但我想我不清楚如何使用它......

在Form_sizechanged事件中执行..

Private Sub Form1_SizeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.SizeChanged
    Me.TabControl1.Width = Me.Width - 20
    myUserControl.Width = Me.TabControl1.Width -20
End Sub
