How do I programmatically change the default text formatting using IConfigLanguage / ISnippetFormat / ConfigLexem

I am trying to implement custom syntax highlighting programmatically as shown here:


I can't work out how to simply change the default text color. Using the Config.xml method you can accomplish this with:

      <format name="Text" Font="Consolas, 12pt"/>

What is the equivalent of this using IConfigLanguage / ISnippetFormat / ConfigLexem?

I tried this:

ISnippetFormat thetext = this.editControl1.Language.Add("text");
thetext.FontColor = Color.Blue;
thetext.Font = new Font("Consolas", 12);

But it's not working for me. I think it's because I need to assign this custom format to something as well?

From what I understand, the below code would change all occurances of the word "stuff" to have a back color of blue:

IConfigLanguage currentConfigLanguage = this.editControl1.Configurator.CreateLanguageConfiguration("Custom_Language");

ISnippetFormat formatMethod = this.editControl1.Language.Add("BlueBackColor");
formatMethod.Font = new Font("Consolas", 12);
formatMethod.BackColor = Color.Blue;

ConfigLexem stuff = new ConfigLexem("stuff", "", FormatType.Custom, false);
stuff.FormatName = "BlueBackColor";


But what I don't understand is how I can apply a custom ISnippetFormat instance to all default text. The examples only show how to link a format method to a ConfigLexem.

Here are my questions:

  1. How do I change the default text color of EditControl programmatically?
  2. What are ALL the ways I can use an ISnippetFormat other than with ConfigLexem?

Thank you for any help. I am new to C# so apologies if this is too basic. I've tried everything I can think of.
