How to Serialize SimpleFont?

[koganam]

You have replaced Font with SimpleFont?

You gave us NinjaTrader.Gui.Design.SerializableFont in NT7. What is the method to serialize SimpleFont in NT8?

Well, that means nothing special to be done, but I do not see SampleFontChange in my installation. What references?

All of these I've looked thru except the Color Region have been converted to NT8 as well.. (haven't looked at them all)

Ah. Now I am too embarrassed to even be here.

An even shorter version should be like this???

[COLOR="RED"]// [NinjaScriptProperty] as for brushes, we don't need this, right?[/COLOR]
 [Display(Name="Large Font", Description="Font Size", Order=1, GroupName="Font")]
 public SimpleFont LargeFont
[COLOR="GREEN"]{ get; set; }[/COLOR]

Set the default value in SetDefaults of OnStateChange():

LargeFont = new SimpleFont("Arial", 14);

With this style we don't need the private variable largeFont. This is one of the best things I see in NinjaScript of NT8. No needs to boringly add private variables for properties.

(correct me if I'm wrong )

Hello ninZa,

Thank you for your contribution and you are correct.

Just a little more information on:

[NinjaScriptProperty]

This tag makes it so the NinjaScript generated code contains an overload for the property. So if you wanted to be able to set the font programatically when adding an indicator to a strategy, you would add the NinjaScriptProperty tag.

But I believe the properties work a little slower than the private variables work when you use them in hard calculations, because extracting or setting a property requires to call an additional method to access it. Ain't I right?

Thanks Michael.

I'm a little embarrassed here Fonts, like brushes, are just for visual displays on chart. But we have no charts when calling an indicator from a strategy or another indicator, that's why brush serialization does not go with NinjaScriptProperty (I believe so). Can you give me an example about a practical use of NinjaScriptProperty for font serialization?

I don't think so, because NT uses "no-variable" style in many of their default NT8 indicators.
But we will wait for an answer from Michael of NT.

The auto-implemented properties are just a design choice as the code is optimized by the compiler. It's just easier to read/debug without having to create and track your own backing field:
