ListBox widget

[victorlevasseur]

This PR adds a ListBox widget. It's based on Zax37 but has almost been entirely rewritten to improve the widget.

Features :

• Vertical scrollbar (never, auto or always)
• Two size "modes": requisition adapted to the max width of items' texts or items' texts shrinked to fit in a not large enough ListBox
• Multiple selection modes: no selection, single selection, multiple selection
• Rendering code in BREW class
• An example is provided, demonstrating 3 types of listboxes

Remarks ?

TODO: When you agreed on this implementation, write the doc (and squash the commits ?)

[victorlevasseur]

Bump.

22 commits? Can't you squash them (at least yours) or something? 😕

[binary1248]

It's easier to review changes when they are batched into fewer changesets.

@binary1248 Can't you just look at the "Files changed" tab?

[binary1248]

I like to checkout the code locally and review it using my own tools.

[victorlevasseur]

Ok, will do it. :)

[victorlevasseur]

The commits are squashed (I did not squash Zax37 commit so that he still appears).

[Zax37]

Thanks for mentioning ;)

[victorlevasseur]

Bump.

I fixed a bug causing the scrollbar not to update when adding or removing items.

Hi,

Is there any desire to follow up on that PR? I have updated to recent master on my local fork. I'll be happy to help getting it merge, it is a really useful widget! One question though, is there any any reason this is not a list of Widgets and not only sf::String? That would allow for more customization (like prepending icons...).

Great job though, I tried it out in a toy project, and it works really well.

I'm also waiting for this one :)
