I'm having some issues with displaying a Combobox and have run out of ideas.

I create the Combobox and ListboxTextItems as shown below:

Code: Select all

CEGUI::Combobox *b = (CEGUI::Combobox*)wm->createWindow("WindowsLook/Combobox", "Listbox");
b->setPosition( CEGUI::Point(0.01f, 0.7f));
b->setSize( CEGUI::Size(0.4f, 0.2f ));
b->setReadOnly(true);

CEGUI::ListboxTextItem *item = new CEGUI::ListboxTextItem( (CEGUI::utf8*)"hello1");
b->addItem(item);

CEGUI::ListboxTextItem *item2 = new CEGUI::ListboxTextItem( (CEGUI::utf8*)"hello2");
b->addItem(item2);

When run, the Combobox get's displayed, but no items are rendered. If I "click" in the pulldown list, my selected item now magically gets rendered in the collapsed Combobox.

It seems the items never get rendered in the pulldown list. Any ideas?

Thanks!

You have to set the colour for the text items. It deafults to white, so in WindowsLook you can't see it :lol:

You might consider a ListboxTextItem sub-class which does this for you, as it saves doing it yourself every time. Also, if you want the selection highlight to work you need to set a selection brush and colour for each item too (this can also be done in your sub-class).

Yup, changing the ListboxTextItem colour did the trick!

One more related question:
How do I get the Combobox to display a default ListboxTextItem?

Thanks!

You mean in the editbox portion?

Just set the text to be the same as one of the combobox items.

Perfect. All it well now!
