Serializing colors

[djkiwi]

Hi Guys, I'd be grateful for some help on serializing colors. This is what I have so far:

//variables
private SolidBrush                 boxoutline            = new SolidBrush(Color.White); 

//Properties
[Category("2. Colors")]
       [Description("Colors.")]
        [Gui.Design.DisplayName("Box Outline color")]
        public Color Boxoutline
        {
            get { return boxoutline.Color; }
            set { this.boxoutline = new SolidBrush(value); }
        }
        
        [Browsable(false)]
        public string BoxoutlineSerialize
        {
        get { return SerializableColor.ToString(boxoutline); }
        set { boxoutline = SerializableColor.FromString(value); }    
        } 

The problem is for the last two lines I'm getting the "The name SerializableColor does not exist in the current context" error. I followed the example exactly.

Any ideas on this one. Thanks in advance. DJ

Opacity

The other problem is being able to set the opacity in the properties section for this. For example I'd like to be able to change the 150 in properties...

graphics.FillRectangle(new SolidBrush(Color.FromArgb(150,Color.Red.R,Color.Red.G,Color.Red.B)), bounds.X +(bounds.Width/2)+1-60, bounds.Top + 2, 59, 59); 

I've have this from another indicator but seems to be fixed at 10 so not sure how to modify it:

[Category("2. Colors")]
        [Description("Colors.")]
        [Gui.Design.DisplayName("Box Opacity")]
        public int Opacity
        {
            get { return opacity; }
            set { opacity = Math.Min(Math.Max(0, value),10); }
        } 

Thanks in advance

DJ, the max is set here to a 10 in the property -

set { opacity = Math.Min(Math.Max(0, value),10);

Are you saying the indicator would set the opacity of the custom Rectangle? I would expect this only to work for the NT default DrawRectangle, as it implements an opacity paramters / setting.

For the color please try with :

[Category("2. Colors")]
[Description("Colors.")]
[Gui.Design.DisplayName("Box Outline color")]
public Color Boxoutline
{
get { return boxoutline.Color; }
set { this.boxoutline = new SolidBrush(value); }
}

[Browsable(false)]
public string BoxoutlineSerialize
{
get { return NinjaTrader.Gui.Design.SerializableColor.ToString( boxoutline); }
set { boxoutline = NinjaTrader.Gui.Design.SerializableColor.FromStrin g(value); }
}

another similar question with regards to color (and opacity). When I change the background color of a panel, is there a way to apply opacity to the background colors?

[NinjaTrader_Bertrand]

Would not be directly supported in NnjaScript, however you can look into setting it via the Color.FromArgb like - BackColor = Color.FromArgb(100, Color.DarkBlue);

For the color please try with :

[Category("2. Colors")]
[Description("Colors.")]
[Gui.Design.DisplayName("Box Outline color")]
public Color Boxoutline
{
get { return boxoutline.Color; }
set { this.boxoutline = new SolidBrush(value); }
}

[Browsable(false)]
public string BoxoutlineSerialize
{
get { return NinjaTrader.Gui.Design.SerializableColor.ToString( boxoutline); }
set { boxoutline = NinjaTrader.Gui.Design.SerializableColor.FromStrin g(value); }
}

Thanks Bertrand, but that didn't work either. Here is a picture of the error. Also, this is how I'm using it so not sure if that is causing the problem as well.

graphics.DrawRectangle(new Pen(boxoutline),  bounds.X +(bounds.Width/2)+60, bounds.Top+1, 60, 60); 

Also this is what I have in variables:

private SolidBrush                 boxoutline            = new SolidBrush(Color.White); 

Thanks. DJ
