꽤 확실하지 왜 이런 일이 일어나고,하지만 난 XNA 색상 값을 수정할 수 있도록하려면 :윈폼 재산권 그리드 나 구조체 값을 변경하는 것을 허용하지 않습니다
private Color _color = Color.White;
[System.ComponentModel.Category("VisibleInEditor")]
[System.ComponentModel.TypeConverter(typeof(System.ComponentModel.ExpandableObjectConverter))]
public Color Color
{
get { return _color; }
set { _color = value; }
}
나는 ExpandableObjectConverter 속성을 가진 생각을 것 문제를 해결했지만 아직 완료하지 않았습니다.
편집 :
public class ColorTypeConverter : ExpandableObjectConverter
{
public override bool CanConvertTo(ITypeDescriptorContext context, System.Type destinationType)
{
return destinationType == typeof(Color);
}
public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, System.Type destinationType)
{
if (destinationType == typeof(string) && value is Color)
{
Color color = (Color)value;
return string.Format("{0}, {1}, {2}, {3}", color.R, color.G, color.B, color.A);
}
else return base.ConvertTo(context, culture, value, destinationType);
}
public override bool CanConvertFrom(ITypeDescriptorContext context, System.Type sourceType)
{
return sourceType == typeof(string);
}
public override object ConvertFrom(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value)
{
if (value is string)
{
try
{
string strVal = value as string;
var parts = strVal.Split(',');
byte r = byte.Parse(parts[0]);
byte g = byte.Parse(parts[1]);
byte b = byte.Parse(parts[2]);
byte a = byte.Parse(parts[3]);
return new Color(r, g, b, a);
}
catch
{
throw new ArgumentException("Can not convert '" + (string)value + "'to type Color");
}
}
else return base.ConvertFrom(context, culture, value);
}
public override object CreateInstance(ITypeDescriptorContext context, System.Collections.IDictionary propertyValues)
{
return new Color((byte)propertyValues["R"], (byte)propertyValues["G"], (byte)propertyValues["B"], (byte)propertyValues["A"]);
}
public override bool GetCreateInstanceSupported(ITypeDescriptorContext context)
{
return true;
}
public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes)
{
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value, attributes);
string[] sortOrder = new string[4];
sortOrder[0] = "R";
sortOrder[1] = "G";
sortOrder[2] = "B";
sortOrder[3] = "A";
// Return a sorted list of properties
return properties.Sort(sortOrder);
}
public override bool GetPropertiesSupported(ITypeDescriptorContext context)
{
return true;
}
}
코드를 업데이트하고 [System.ComponentModel.TypeConverter (typeof (System.ComponentModel.ExpandableObjectConverter))]를 CustomConverter로 바꿉니다. – Antonio
