自定义 winforms 标签控件中的对齐

Alignment in custom winforms label control

我使用了这个答案:Alpha in ForeColor 与默认标签不同,创建允许通过 ARGB 淡入淡出的自定义标签元素。

using System;
using System.Drawing;
using System.Windows.Forms;

public class MyLabel : Label {
  protected override void OnPaint(PaintEventArgs e) {
    Rectangle rc = this.ClientRectangle;
    StringFormat fmt = new StringFormat(StringFormat.GenericTypographic);
    using (var br = new SolidBrush(this.ForeColor)) {
      e.Graphics.DrawString(this.Text, this.Font, br, rc, fmt);
    }
  }
}

我很好奇我将如何在此 class 中实现 TextAlign 以允许正确对齐文本内容。

感谢@Aybe 的评论,我发现我需要像这样将 Alignment 添加到 StringFormat var fmt:

fmt.Alignment = StringAlignment.Center;

使整个 class 看起来像这样:

using System;
using System.Drawing;
using System.Windows.Forms;

public class MyLabel : Label {
  protected override void OnPaint(PaintEventArgs e) {
    Rectangle rc = this.ClientRectangle;
    StringFormat fmt = new StringFormat(StringFormat.GenericTypographic);
    fmt.Alignment = StringAlignment.Center;
        using (var br = new SolidBrush(this.ForeColor))
        {
            e.Graphics.DrawString(this.Text, this.Font, br, rc, fmt);
        }
    }   
}
