I am working an Acrobat plugin (SDK acrobat 8) which uses Qt Widgets. It works fine with Qt 4.3.4.
After upgrading to Qt 4.6.4 carbon, it is no longer possible to see Acrobat's menu if QApplication is instanciated.
int argc = 0;
(void)new QApplication(argc, 0, true);
With those 3 lines, the acrobat menu does not load, neither can it be quit other than with a force quit.
There are no warning messages, everything seems to be working fine, except that is really does not.
Without those 3 lines, acrobat works well as long as not widgets are created (see QApplication doc).
Thanks for whatever information you may have
The solution was to use
qApp->setAttribute(Qt::AA_MacPluginApplication,true); insead of
