有时需要把checkbox的大小变大一些。可参照以下sample code自行调整为项目需要。
实现代码：
class MyCheckBox : CheckBox
{
public MyCheckBox()
{
this.TextAlign = ContentAlignment.MiddleRight;
}
public override bool AutoSize
{
get { return base.AutoSize; }
set { base.AutoSize = false; }
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
int h = this.ClientSize.Height - 2;
Rectangle rc = new Rectangle(new Point(0, 1), new Size(h, h));
ControlPaint.DrawCheckBox(e.Graphics, rc,
this.Checked ? ButtonState.Checked : ButtonState.Normal);
}
}
