the code wo give trouble is a ui file...
the C++ code result is from qmake.....

http://ciz.ch/svnciz/forms_shop/form...ui/tab_addo.ui

get file tab_addo.ui

and
uic -o ui_tab_addo.h tab_addo.ui
that is the trouble code .... wo not display pngs icon...on mac and window show...

if you download and test
svn co http://ciz.ch/svnciz/forms_shop/ tester
cd tester && qmake && make

you dont need qt4 plug-ins... sqlite3 staticlibs is inside!
and config is on bin Destdir make...
by import db you donwload only master table...
