Add option to autoscroll Paragraph when appending text

[Chillance]

Hey,

I noticed there doesn't seem to be any kind of autoscroll feature when inserting new text with par.Text += "Text\n" and it is at the bottom. It would be nice to have this boolean available.

Also, it doesn't seem to be possible to not wrap text inside the par (when using the layout at least). Meaning, text will wrap as you decrease the width. This works fine with lists though.

Thanks

Just added the TextWrap option to the Paragraph widget that allows you to toggle line wrapping. So that leaves us with the autoscroll feature left to implement.

Any update to the auto scroll ? I have done something like this.

func message(color, text string) {
    ss := strings.Split(logs.Text, "\n")
    pos := len(ss) - 16
    if pos < 0 {
        pos = 0
    }
    logs.Text = strings.Join(ss[pos:], "\n") + "[" + text+ "]" + color + "\n"
    ui.Render(logs)
}
