Docs: Text fields

[seasonedfish]

Hello, I would like to use this library to create a text field for my mod, but the wiki page for this is empty. I would appreciate it if a guide were added on how to create text fields.

Here's a minimal example for it (excluding imports):

public class TextFieldTest extends LightweightGuiDescription {
  public TextFieldTest() {
    WGridPanel root = new WGridPanel();
    setRootPanel(root);

    WTextField field = new WTextField();
    field.setHost(this); // input won't work if the 'host' is not set
    add(field, 0, 0, 5, 1); // height can be any, WTextField#setSize overrides any given y value with 20px

    root.validate(this);
  }

  public static CottonClientScreen createScreen() {
    return new CottonClientScreen(new TextFieldTest());
  }
}

But beware it doesn't support multiline input or output if that's what you need. (see #158)

[Juuxel]

field.setHost(this); // input won't work if the 'host' is not set

FYI, this line isn't needed if you have the root.validate(this) call as expected (the host is set there).

Thanks!

Oh wait, the wiki page is still empty: https://github.com/CottonMC/LibGui/wiki/Text-fields
@Juuxel could you update it? It says I don't have permission to update it.
