ItemListbox double click

Postby dewyatt » Mon Sep 01, 2008 14:44

I would like to respond to double click events in an ItemListbox.
Does such an event exist?

Also, how would I allow editing in an ItemListbox?
I don't think this is directly supported, but how would I add it?

Regarding events, you can answer these questions yourself by reading through the tutorials/API. But here you go anyway:

Code: Select all

_pListbox->subscribeEvent(CEGUI::ItemListbox::EventMouseDoubleClick, CEGUI::Event::Subscriber(&WinMain::OnMouseDoubleClick, this));


Regarding activly editing listbox items, you can derive the solution from this wiki page: http://www.cegui.org.uk/wiki/index.php/Create_a_CheckListboxItem

I was going to implement this same functionality previously, so I can post some example code for you. In the end I decided to take a different route, so you may need to delve a bit deeper yourself:

Based on WindowsLook.looknfeel:

Code: Select all

Thanks.
I've read through the documentation and tutorials.
ItemListbox has a longer hierarchy than most and the documentation won't show the full hierarchy on its class page.
So I somehow didn't realize it did, ultimately, derive from Window (should have known but I guess I wasn't thinking).

Thanks a lot for the looknfeel, that should be helpful.
