最近在使用SunnyUI的控件写东西,遇到非常难受的问题,Button不支持换行,下载了Sunny UI源码,修改内容如下
找到UIButton代码新增重写
private string _text;
// 重写 Text 属性
[Editor("System.ComponentModel.Design.MultilineStringEditor, System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor))]
public override string Text
{
get { return _text; }
set
{
if (_text != value)
{
_text = value;
Invalidate();
}
}
}
找到重绘文件修改如下
public static void DrawString(this Graphics g, string str, Font font, Color color, Size size, Padding padding, ContentAlignment align)
{
if (str.IsNullOrEmpty()) return;
SizeF sf = g.MeasureString(str, font);
using (Brush br = color.Brush())
{
StringFormat stringFormat = new StringFormat
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center
};
stringFormat.FormatFlags = StringFormatFlags.LineLimit;
switch (align)
{
case ContentAlignment.MiddleCenter:
//g.DrawString(str, font, br, padding.Left + (size.Width - sf.Width - padding.Left - padding.Right) / 2.0f,
// padding.Top + (size.Height - sf.Height - padding.Top - padding.Bottom) / 2.0f,stringFormat);
RectangleF rect = new RectangleF(0, 0, size.Width, size.Height);
g.DrawString(str, font, br, rect, stringFormat);
break;
case ContentAlignment.TopLeft:
g.DrawString(str, font, br, padding.Left, padding.Top);
break;
case ContentAlignment.TopCenter:
g.DrawString(str, font, br, padding.Left + (size.Width - sf.Width - padding.Left - padding.Right) / 2.0f, padding.Top);
break;
case ContentAlignment.TopRight:
g.DrawString(str, font, br, size.Width - sf.Width - padding.Right, padding.Top);
break;
case ContentAlignment.MiddleLeft:
g.DrawString(str, font, br, padding.Left, padding.Top + (size.Height - sf.Height - padding.Top - padding.Bottom) / 2.0f);
break;
case ContentAlignment.MiddleRight:
g.DrawString(str, font, br, size.Width - sf.Width - padding.Right, padding.Top + (size.Height - sf.Height - padding.Top - padding.Bottom) / 2.0f);
break;
case ContentAlignment.BottomLeft:
g.DrawString(str, font, br, padding.Left, size.Height - sf.Height - padding.Bottom);
break;
case ContentAlignment.BottomCenter:
g.DrawString(str, font, br, padding.Left + (size.Width - sf.Width - padding.Left - padding.Right) / 2.0f, size.Height - sf.Height - padding.Bottom);
break;
case ContentAlignment.BottomRight:
g.DrawString(str, font, br, size.Width - sf.Width - padding.Right, size.Height - sf.Height - padding.Bottom);
break;
}
}
}
实在找不到就全工程搜索,
