Possible to add 'DashStyleHelper' as enum for User Input?

permalink · November 19th, 2020, 04:29 PM

Imagine you want to draw a line of the form:

Code

Draw.Line(this, "line", false, 10, High[10], 0, High[10], Brushes.Cyan, DashStyleHelper.Dot, 1);

For the DashStyleHelper bit... is it possible to add this in a user input in a way that would allow the user to select from the available options of a line? I.e.,

Dash
DashDot
DashDotDot
Dot
Solid

In the same way you can add a Brush color as a user input via:

Code

		[NinjaScriptProperty]
		[XmlIgnore]
		[Display(Name="Some Color", Order=1, GroupName="1)MyColors")]
		public Brush MyColor
		{ get; set; }

		[Browsable(false)]
		public string MyColorSerializable
		{
			get { return Serialize.BrushToString(MyColor); }
			set { MyColor= Serialize.StringToBrush(value); }
		}

You can with an enum and a switch. Example right here:

I just happened to stumble across an indie that did this the other day. So posting just in case someone else has such a need.

In the class level, can add:

Code

		private PlotStyle	myPlotStyle = PlotStyle.Line;
		private DashStyleHelper	myDashStyle  = DashStyleHelper.DashDot;

In the properties section for a user input:

Code

		[Display(ResourceType = typeof(Custom.Resource), Name = "", Description = "", GroupName = "Plot Parameters", Order = 0)]
		public PlotStyle MyPlotStyle				        
		{	
                         get { return myPlotStyle; }
                         set { myPlotStyle = value; }
		}
		
		[Display(ResourceType = typeof(Custom.Resource), Name = "", Description = "", GroupName = "Plot Parameters", Order = 1)]
		public DashStyleHelper MyDashStyle				        
		{
			get { return myDashStyle; }
			set { myDashStyle = value; }
		}

The dashstyleHelper can be used in methods such as Draw.Line() or other on-chart drawings.

Both of the above items can be used in standard plots, and configured in onStateChange() like:

Code

			else if (State == State.Configure)
			{
				Plots[0].PlotStyle = myPlotStyle;
				Plots[0].DashStyleHelper = myDashStyle;	
                        }

Updating in the case someone else may want more custom user inputs in a simple fashion(I'm sure plenty of people that already know how to do this, but just in case there are other novices out there like me).

Here is an example of creating a simpleFont object that can be configured as a user input. It is really cool, convenient, as it gives you a user input that offers you a bit of control in the input screen.

You can configure the fontFamily AND size with a dropdown, and some other features. It's pretty slick. Text color you still would have to add in manually a separate user input as you can see in my image.

At the class level, you add:

Code

private SimpleFont myTextFont = new NinjaTrader.Gui.Tools.SimpleFont("Impact", 12);

In the properties section, you'd add:

Code

		[XmlIgnore]
		[Display(ResourceType = typeof(Custom.Resource), Name = "Text Type", Description = "", GroupName = "Text Control", Order = 0)]
		public SimpleFont MyTextFont
		{ 
			get {return myTextFont;}
			set {myTextFont = value;}
		}
