Question

Is there an easy way to make elements in tripleplay wrap and continue below?

For example if I have this code:

    Group letters = new Group(AxisLayout.horizontal(), Style.HALIGN.left);
    letters.addStyles(Styles.make(Style.TEXT_WRAP.is(true)));
    root.add(letters);

    for (int i = 0; i < 100; i++) {
        letters.add(new Label(""+i));
    }

That would show some numbers (up to, say, 30) and the rest of the numbers will dissappear off-screen, what I want to have is something like:

01 02 03 ... 28
29 30 31 ... 50

So whatever component doesn’t fit on screen will be added below. I tried a few settings but wasn’t able to get it

Thanks

Style.TEXT_WRAP is only applicable to Labels. There is no equivalent in Tripleplay UI of Swing’s FlowLayout which is what I think you want.

If you really just want to lay out a bunch of text, then just stick it all in one label with text wrapping enabled. But if you’re trying to layout actual user interface elements in a flow, then you’ll need to write your own FlowLayout. You can also use TableLayout, but that requires that you know how many columns you want in advance.

I’ve always found FlowLayout to be a weird way to lay out user interfaces, and have never had a need for it, hence I did not write one for Tripleplay UI.
