The lack of display precision has to do with the fact that you're
using an FXDataTarget to update the value of the text field.
When the FXTextField sets its text from the double-precision float
value that it gets from the FXDataTarget, it uses a fixed format like:
sprintf(str, "%.*G", 6, value);
To use a custom formatting, you'd need to stop using FXDataTarget and
instead use a combination of SEL_COMMAND and SEL_UPDATE, e.g.
@value = @value_value.text.to_f
@value_value.text = @value.to_s # or however you want to format it
Hope this helps,
