试图让 tabcontrol 的每个选项卡上的文本垂直显示。因为我从来没有涉足控制和什么不是，我有点卡住了。找到了一些代码来让文本显示为好像它向左旋转一样。我希望它显示为好像它在选项卡上向右（垂直）旋转。骨架代码如下：

Protected Sub OnDrawItem(ByVal sender As Object, ByVal e As DrawItemEventArgs) Handles TabControl1.DrawItem
    'MyBase.OnDrawItem(e)'
    Dim tc As TabControl = DirectCast(sender, TabControl)
    Dim g As Graphics = e.Graphics
    Dim rectf As RectangleF
    Dim isVertical As Boolean = (tc.Alignment > TabAlignment.Bottom)
    Dim off As Integer = 1 : If (e.State And sel) = sel Then off = -1
    Dim textFormat As New StringFormat(StringFormatFlags.NoClip _
                               Or StringFormatFlags.NoWrap)
    With textFormat
        .HotkeyPrefix = System.Drawing.Text.HotkeyPrefix.Show
        .Alignment = StringAlignment.Center
        .LineAlignment = StringAlignment.Center
    End With


    With e.Bounds
        If isVertical Then
            ' tabs are aligned left or right'
            If tc.Alignment = TabAlignment.Left Then
                Dim m As New System.Drawing.Drawing2D.Matrix
                m.Translate(0, .Height - tc.TabPages(0).Top)
                m.RotateAt(270, New PointF(.X, .Y))
                g.Transform = m
                rectf = New RectangleF(.Left - tc.TabPages(0).Top, .Top + off, _
                                       .Height, .Width)
            ElseIf tc.Alignment = TabAlignment.Right Then
                'Dim m As New System.Drawing.Drawing2D.Matrix'
                'm.Translate(0, .Height - tc.TabPages(0).Top)'
                'm.RotateAt(270, New PointF(.X, .Y))'
                'g.Transform = m'
                'rectf = New RectangleF(.Left - tc.TabPages(0).Top, .Top + off, _'
                '                       .Height, .Width)'
                ' Here is where the tab should go to rotate the text about 180 degrees'
            End If
        Else
            ' tabs are aligned top or bottom'
            rectf = New RectangleF(.X, .Y + off, .Width, .Height)
        End If
    End With


    Dim col As Color
    Select Case (e.State And notsf)
        Case DrawItemState.Disabled
            col = SystemColors.GrayText
        Case DrawItemState.HotLight
            col = SystemColors.HotTrack
        Case Else
            col = SystemColors.MenuText
    End Select


    g.DrawString(tc.TabPages(e.Index).Text, _
                 tc.Font, _
                 New SolidBrush(col), _
                 rectf, _
                 textFormat)

    If isVertical Then g.ResetTransform()

    If (e.State And selfoc) = selfoc Then
        ControlPaint.DrawFocusRectangle(g, _
                  [Rectangle].Inflate(e.Bounds, -1, -1))
    End If
    textFormat.Dispose()
End Sub

我假设您正在使用 XAML，这可以通过样式实现

添加这些样式：

    <!-- Simple Splitter Style -->
    <Style x:Key="SimpleSplitterStyle" TargetType="controls:GridSplitter">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="controls:GridSplitter">
                    <Grid x:Name="Root" IsHitTestVisible="{TemplateBinding IsEnabled}">
                        <Rectangle Fill="{TemplateBinding Background}" StrokeThickness="0"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <!-- Tab Item Header (Right) -->
    <Style x:Key="RightTabItemHeader" TargetType="ContentControl">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" ContentTemplate="{TemplateBinding ContentTemplate}">
                        <layout:LayoutTransformer >
                            <layout:LayoutTransformer.LayoutTransform>
                                <RotateTransform Angle="90"/>
                            </layout:LayoutTransformer.LayoutTransform>
                            <ContentPresenter Margin="5,0,5,0" />
                        </layout:LayoutTransformer>

                                <RotateTransform Angle="-90"/>
                            </layout:LayoutTransformer.LayoutTransform>
                            <ContentPresenter Margin="5,0,5,0" />
                        </layout:LayoutTransformer>
                    </ContentPresenter>
                </ControlTemplate>

    </Style>

然后您可以将其分配给每个选项卡项：

            <controls:TabControl TabStripPlacement="Right" Margin="4">
            <controls:TabItem Header="First" Style="{StaticResource TabItemStyle}">
                <controls:TreeView>
                    <controls:TreeViewItem Header="Parent 1" />
                    <controls:TreeViewItem Header="Parent 2">
                        <controls:TreeViewItem Header="Child 1">
                            <controls:TreeViewItem Header="Grandchild 1" />
                        </controls:TreeViewItem>
                    </controls:TreeViewItem>
                    <controls:TreeViewItem Header="Parent 3">
                        <controls:TreeViewItem Header="Child 1">
                            <controls:TreeViewItem Header="Grandchild 1" />
                            <controls:TreeViewItem Header="Grandchild 2" />
                        </controls:TreeViewItem>
                    </controls:TreeViewItem>
                </controls:TreeView>
            </controls:TabItem>
            <controls:TabItem Header="Second" Style="{StaticResource TabItemStyle}">
                <controls:TreeView>
                    <controls:TreeViewItem Header="Parent 1" />
                    <controls:TreeViewItem Header="Parent 2">
                        <controls:TreeViewItem Header="Child 1">
                            <controls:TreeViewItem Header="Grandchild 1" />
                        </controls:TreeViewItem>
                    </controls:TreeViewItem>
                    <controls:TreeViewItem Header="Parent 3">
                        <controls:TreeViewItem Header="Child 1">
                            <controls:TreeViewItem Header="Grandchild 1" />
                            <controls:TreeViewItem Header="Grandchild 2" />
                        </controls:TreeViewItem>
                    </controls:TreeViewItem>
                    <controls:TreeViewItem Header="Parent 4">
                        <controls:TreeViewItem Header="Child 1">
                            <controls:TreeViewItem Header="Grandchild 1" />
                            <controls:TreeViewItem Header="Grandchild 2" />
                            <controls:TreeViewItem Header="Grandchild 3" />
                            <controls:TreeViewItem Header="Grandchild 4" />
                            <controls:TreeViewItem Header="Grandchild 5" />
                            <controls:TreeViewItem Header="Grandchild 6" />
                            <controls:TreeViewItem Header="Grandchild 7" />
                            <controls:TreeViewItem Header="Grandchild 8" />
                        </controls:TreeViewItem>
                    </controls:TreeViewItem>
                </controls:TreeView>
            </controls:TabItem>
        </controls:TabControl>

现在您可以从上/下/右/左更改，文本将在右/左垂直。在这个例子中我只留下了顶部和底部，但这应该会给你很多关于如何控制这些选项卡的想法。

我不使用 VB 或 WinForms，因此以下内容不会出现在代码中，并且包含一些猜测。如果没有屏幕截图，也很难从描述中知道与您想要的内容有什么不同。我是否认为您只是希望标签的标题文本以另一种方式旋转 180 度，即文本的“顶部”靠在标签的左侧或标签的右侧，无论现在不是哪个？

在分支中，If tc.Alignment = TabAlignment.Right Then ...您的文本被 RotateAt 调用旋转：

m.RotateAt(270, New PointF(.X, .Y))

并且您需要将 270 更改为 90 以使文本向另一个方向旋转。

（您熟悉设置这样的转换矩阵吗？同样的原则适用于 OpenGL 或 DirectX 编程。如果不熟悉，请发表评论，我会解释/链接。）

如果你只是这样做，那么文本很可能是不可见的，因为它会被旋转到你正在绘制的位图之外。您需要翻译它，使文本的开头位于右上角。这就是我上面提到的猜测出现的地方：我不熟悉您正在使用的图形框架的坐标系，所以我不知道要翻译哪个方向。很抱歉，我不能给你工作代码，但我只是没有 Visual Studio 和 .Net Winforms 控件来试验:) 我可以看到你已经在做这些事情了：

m.Translate(0, .Height - tc.TabPages(0).Top)

我的猜测是您需要更改此设置，以便 X 坐标 (0) 为.Width或.Width - [text height, calculate this]，并且您可能还需要考虑 Y 坐标中的文本宽度。（文本“高度”和“宽度”就好像文本是水平/正常绘制的。）我很确定.Net的绘图框架可能包括Graphics TextHeight(...)和TextWidth(...)方法，如果不是这些名称，我确定它们'很容易找到:) TextRect()也许？

（如果我坐在你的电脑前并试图通过纯粹的猜测来解决这个问题，我会编写这段代码，以便它在一个大位图的中间旋转文本，修改它使其位于位图的左上角在一个选项卡大小的矩形内的正确位置，然后将代码移动到选项卡绘图方法。省去了所有的麻烦，因为有一个很小的选项卡并运行它并在它不可见时显示“我的文本在哪里？”，因为它正在被绘制在错误的坐标。）
