Qt Designer's Widget Box buttons

[Nb2Qt]

Silly question:

How are the category disclosure buttons seen in Designer's widget box actually drawn? They are the ones with the tiny +- on the left and centered text like "Spacers", "Layouts", etc. I'd like to make a similar button and was curious how the Qt gurus implemented it. I searched the Designer source but never really found the specifics.

I realize they are using a TreeWidget so the actual show/hide happens as usual.

Is the +- surrounded by a box simply a standard Qt style option?

Thanks,

See SheetDelegate::paint() in tools/designer/src/lib/shared/sheet_delegate.cpp.

Awesome, that was it. Thanks so much.

Included within the whole paint function, an important piece (at least for me) was usage of the QStyle::PE_IndicatorBranch and how one graphic was layered after another.
