ListBox with multi select

[tom_gamer]

Hi,

I had to write a little extension of the Listbox for my game.
With the code, you can make a ListBox do multiselect (select more than one item).


This works only with mouse control (keyboard is not implemented for multiselect).

Here is the code based on irrlicht 1.8. Simply overwrite the existing files (in include dir and source/Irrlicht dir).

You can use something like http://ideone.com/ for posting code. Sorry, but longer code-posts don't work in the forum (don't know why really, I wish it would work).

Assuming it's clean of bugs, with your permission tom_gamer, we could put this in irrExt (our humble repositories). Someone (probably me) would have to double check for bugs and such.

Is there a specific reason why you named it IGUIListBox? I imagine you could have called it IGUIListBox2 and simply written an IGUIFactory implementation for it.

Thanks for posting. I'll look at it if I ever try adding multiselect again (I already have 2 implementations, but both times didn't like 'em enough to add them to the engine itself).

Looks good!

Created a patch for easier review:

I see. Advantage that it doesn't change the interface much. Disadvantage would be that you always have to set all selected together instead of independent. I suppose setMultiSelect could be an internal protected member of the implementation class in this patch.

Permission given. (Keep in mind, that the code is mainly Irrlicht, that is licenced under zlib licence.)

I replaced the original files in my project. I'm using the guieditor often. So I don't had to re-compile it.

I would appreciate it if this functionality get's into the main Irrlicht stream. You may change the interface, of course...
