Font property...

[Mark--]

Hello,

I am attempting to create a font property, found a thread that talked about it and it does not fully work, for me.

Using version 8.0.27.1 64-bit

if (State == State.SetDefaults)

NinjaTrader.Gui.Tools.SimpleFont shortFont = new NinjaTrader.Gui.Tools.SimpleFont("Consolas", 16) { Size = 32, Bold = false};
...

[Display(Name="Font", Description="Display font", GroupName="Short")]
public NinjaTrader.Gui.Tools.SimpleFont shortFont
{ get; set; }
​

The property does show in the dialog but does not expand when selected.


Ideas?

Thanks,

Mark

NinjaTrader or a knowledgable user can chime in if there is an inbuilt type convertor for this. Otherwise, you could make a custom type converter to make this work. Basically a type converter just converts an arbitrary type to and from a string so that the string can be stored and worked with in the UI. A similar mechanism lets you custom-populate a dropdown control as if it were an enum, but really, it's just a list you made of the fonts.

Thanks for the response Bruce.
I found a thread from 2017 that showed the code I posted with an image of the properties dialog and it worked.

Hello Mark--,

Like other nullable types, you must set a default value for the property for this to display in the UI without errors occurring.

Attached is an example.

Thanks for the response ChelseaB.

I had done that but your post got me to look at my code again and I found my error, in bold


if (State == State.SetDefaults)

NinjaTrader.Gui.Tools.SimpleFont shortFont = new NinjaTrader.Gui.Tools.SimpleFont("Consolas", 16) { Size = 32, Bold = false};


Removed the bold and worked as expected.

Hello Mark--,

This would fall under general C# education, however any variable can only be used in the scope in which it is declared.

If you declare a variable in a method, it can only be used in that method. If you declare a variable in the action block of an if statement (branching command) that variable can only be used in that action block and not outside of it.

Your variable was already declared in the scope of the class as public. It doesn't need to be declared a second time in the method.

Right. It was a copy and paste from a strategy I wrote and did not properly look over the paste.

Thanks for your time.
