选项卡控件,具有垂直对齐文本的垂直对齐选项卡

这是本机Windows选项卡控件的视觉样式呈现器中的一个古老错误。它只支持顶部的标签,我猜是微软的程序员在完成任务之前被一辆公共汽车碾过了。

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

public class FixedTabControl : TabControl {
    [DllImportAttribute("uxtheme.dll")]
    private static extern int SetWindowTheme(IntPtr hWnd, string appname, string idlist);

    protected override void OnHandleCreated(EventArgs e) {
        SetWindowTheme(this.Handle, "", "");
        base.OnHandleCreated(e);
    }
}

如果创建自己的DrawItem事件,则可以手动编写选项卡标题。您可以使用以下过程:

 Property  |  Value
 ----------|----------------
 Alignment |  Right (or left, depending on what you want)
 SizeMode  |  Fixed
 DrawMode  |  OwnerDrawFixed

2) 将ItemSize.Width属性设置为25,将ItemSize.Height属性设置为100。根据需要调整这些值,但请记住,基本上,宽度就是高度,反之亦然。

private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{
  Graphics g = e.Graphics;
  Brush _TextBrush;

  // Get the item from the collection.
  TabPage _TabPage = tabControl1.TabPages[e.Index];

  // Get the real bounds for the tab rectangle.
  Rectangle _TabBounds = tabControl1.GetTabRect(e.Index);

  if(e.State == DrawItemState.Selected)
  {
    // Draw a different background color, and don't paint a focus rectangle.
    _TextBrush = new SolidBrush(Color.Red);
    g.FillRectangle(Brushes.Gray, e.Bounds);
  }
  else
  {
    _TextBrush = new System.Drawing.SolidBrush(e.ForeColor);
    e.DrawBackground();
  }

  // Use our own font. Because we CAN.
  Font _TabFont = new Font("Arial", 10, FontStyle.Bold, GraphicsUnit.Pixel);

  // Draw string. Center the text.
  StringFormat _StringFlags = new StringFormat();
  _StringFlags.Alignment = StringAlignment.Center;
  _StringFlags.LineAlignment = StringAlignment.Center;
  g.DrawString(_TabPage.Text, _TabFont, _TextBrush, 
               _TabBounds, new StringFormat(_StringFlags));
}

4) 利润!
