First. Your code should create a memory leak.
Cause addAction will make a copy of icon and you never delete result of
colorize
Look at declaration:
QAction **addAction <qtoolbar.html#addAction-5>* ( const QIcon & *icon*,
const QString & *text*, const QObject * *receiver*, const char *
*member* )Second.
You did not clarify what "does not work" means.
Anyway my guess you should either set
use QToolbar::setIconSize to the size of your pixmap or add compatible (by
size ) pixmap to your icon.
The icons you are using are definitely not compatible with default toolbar
icon sizes, so at the best the enabled icon is auto scaled, then greyed and
that what you may see, at the wrse you see no icon at all ( sorry too lazy
to test).

Alex
