c# - 如何将 TabPage 的标题文本设为粗体？

Question

我在 C# Windows 应用程序中有一些 tabControl。它有一些tabPages。有谁知道如何使 tabPage 文本变为粗体..？

Answer 1

您需要处理 TabControl 的 DrawItem 事件以手动绘制标题。注意:受影响控件的 DrawMode 应设置为 TabDrawMode.OwnerDrawFixed。

这是一个示例:

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.Blue);
        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(e.Font.FontFamily, (float)9, FontStyle.Bold, GraphicsUnit.Pixel);
    //Font fnt = new Font(e.Font.FontFamily, (float)7.5, FontStyle.Bold);

    // Draw string. Center the text.
    StringFormat _StringFlags = new StringFormat();
    _StringFlags.Alignment = StringAlignment.Center;
    _StringFlags.LineAlignment = StringAlignment.Center;
    g.DrawString(tabControl1.TabPages[e.Index].Text, _TabFont, _TextBrush,
                 _TabBounds, new StringFormat(_StringFlags));

}
