Requested Feature #3341 = breakWhenNeeded

[caticHarun]

closes #3341

This feature adds a property "breakWhenNeeded".

If breakWhenNeeded=true and element cannot fit on the page, then it adds a page break before

The main difference between wrap=false and breakWhenNeeded=true is that in wrap={false} the element is limited on one page. Whereas in breakWhenNeeded=true, it only adds a break before and it continues on as it should

I don't think I understand the difference between break and breakWhenNeeded (nor I like the name of the prop too much :))

[caticHarun]

break=true always makes a page break

But breakWhenNeeded adds a page break if the element is going to wrap on another page. But if that element is bigger than the whole page (e.g if is is bigger than the A4 Format), then it continues normally (with a page break before)

Here is the use case I am going for.

Imagine an invoice style application, that makes pdfs

You have headers, products and lastly total.

If you have a couple of items, then you want the total on the same page.

But if you have a bit more items, the total gets wrapped on another page

The goal is to add a page break if it wraps, and if it does not, then leave it on the same page

Currently you can do this with wrap=false, but the issue is, when the element is too big to fit on one page, it tries to squeze everything on one paper which can lead to this:

And with breakWhenNeeded

Name of the prop is not important, it can always be changed :)
