Changing Draw.Text color (dynamically maybe)

[sakura1337]

Hi so I am writing an indicator that displays text to the chart, and on light mode its working properly as the text is rendering as black text. However if I switch to dark mode the text is invisible because it is still black text...

I know we can see the current theme with:

 NinjaTrader.Core.Globals.GeneralOptions.Skin

And this is my current draw code:

 Draw.Text(this, "myText", "black Text", -4, High[0] - ((High[0] - Low[0]) / 2));

How do I edit the Draw.Text color? Any code examples or help would be greatly appreciated.

Also followup: If anyone can explain how a user could change this in indicator options that would be awesome.

I was able to find a solution and will post my code here incase anyone else need help on this.

In your indicator SetDefaults you can define a brush to hold the text color:

TextColor = Brushes.Black;

And have the user choose the text color in properties:

    [NinjaScriptProperty]
        [XmlIgnore]
        [Display(Name = "Text Color", Description = "Color of text", Order = 12, GroupName = "Colors")]
        public Brush TextColor
        { get; set; }​

Also we want two more variables for my example, one to change font options (also goes in the SetDefaults)

TextFont = new NinjaTrader.Gui.Tools.SimpleFont("Arial", 12);

And in our properties we make them able to edit the font style:

    [Display(Name = "Font, size, type, style",
            Description = "Select font, style, size to display on chart",
            GroupName = "Text",
            Order = 1)]
        public Gui.Tools.SimpleFont TextFont
        { get; set; }​

Finally for our actual draw method:

Brush empty = Brushes.Transparent;
// See Draw.Text in your IDE for all argument types.
Draw.Text(this, "yourLabel", false, "yourText", 0, High[0] - ((High[0] - Low[0]) / 2), 0, TextColor, TextFont, TextAlignment.Center, empty, empty, 0);

Ill try to check this thread if anyone needs more assistance.
