How to set Button icons from UniCode characters?

[tcdouglas]

Many of the NT buttons (particularly in the tool bar of the Chart window) have an icon determined by a single UniCode character set in the button's content property.

For example, the Show Data Box button has a UniCode character of 57391 which determines its icon:



There's also a mention of this in the NT Help https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?using_images_and_geo metry_with_custom_icons.htm

"you can use a variety of inputs to specify what will be displayed on the icon, including UniCode characters (if they exist in the icon pack for the font family used in NinjaTrader)"

Unfortunately, there's no example how to do this. I've tried the following (copied from the Show Data Box button), but it does not show any icon:


What property setting am I missing to make this work? I'm simply trying to re-use the NT icons in my own custom button using the UniCode value, the same way that NT does it.

Hello tcdouglas,

Some further information can be found from the forum post below.

I've re-posted the link as the link you have leads to a 404.

Hi Chelsea B,

Thank you for your advice, which I'll certainly look at.

However, I have noticed a difference between what I'm doing and what NT is doing. The FontFamily created by NT included a BaseUri that takes into account the currently selected theme:



However, my FontFamily does not:



So I think this question boils down to: How do I create a FontFamily that takes into account the currently selected theme?

Obviously hard-coding the BaseUri is not a solution as it wouldn't change if the selected theme changes.

...hmm, if I hard-code the BaseUri (so it matches the NT button), it's still not working.

Hello tcdouglas,

This would be an advanced C# concept and is not fully supported by the Scripting Support team.

There can be limitations using unsupported code and advanced C# concepts in a NinjaScript, so your mileage may vary. As of now, we do not have any examples that can be used to navigate that path.

I asked our development about this and let me know:
"The icons we use are a custom font we make." ... 'I don't believe they (the font file) can be accessed by clients at all."

They have provided the font file if you find this helpful.

...I've worked out how to do it with 1 line of code:





FYI also found out you can get the icons font family with:
