我创建了自定义TextBox，但是当我将其Font设置为新的 public class TextLayer : TextBox
{
public TextLayer()
{
SetStyle(ControlStyles.SupportsTransparentBackColor |
ControlStyles.OptimizedDoubleBuffer |
ControlStyles.AllPaintingInWmPaint |
ControlStyles.ResizeRedraw | ControlStyles.UserPaint, true);
BackColor = Color.Transparent;
BorderStyle = BorderStyle.None;
//font = new Font(FontFamily.GenericMonospace, 20);
Font = new Font(FontFamily.GenericMonospace, 20);
Size = new Size(22, 22);
}
protected override void OnTextChanged(EventArgs e)
{
base.OnTextChanged(e);
var size = TextRenderer.MeasureText(Text, Font);
if (size.Width < 30)
Width = 30;
else
Width = size.Width;
if (size.Height < 30)
Height = 30;
else
Height = size.Height;
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
ControlPaint.DrawBorder(
e.Graphics, ClientRectangle,
Color.White, 1, ButtonBorderStyle.Dotted,
Color.White, 1, ButtonBorderStyle.Dotted,
Color.White, 1, ButtonBorderStyle.Dotted,
Color.White, 1, ButtonBorderStyle.Dotted);
}
}
时，它无法正常工作：
TextBox我在这里想念什么，迫使queryString呈现它的默认字体？
编辑： C# How to change font of a label我已经在我的代码中执行此操作并且它无法正常工作，那么它是如何重复的？
