Hi Mikhail,
did I understand correctly that this issue only appears if you create the
QtSingleApplication yourself in your own method? You might want to take a look
at how we handle the Qt application creation in
void BaseApplication::initializeQt()
{
if (qApp) return;
// If previously parameters have been set we have to store them
// to hand them through to the application
QString appName = this->getApplicationName();
QString orgName = this->getOrganizationName();
QString orgDomain = this->getOrganizationDomain();
// Create a QCoreApplication instance
this->getQApplication();
// provide parameters to QCoreApplication
this->setApplicationName(appName);
this->setOrganizationName(orgName);
this->setOrganizationDomain(orgDomain);
}
basically we store the names separately as long as the application does not
exist yet and upon creation hand them through.
Does this fit your problem?
Best,
Caspar

Betreff: [mitk-users] mitk::BaseApplication can't set OrganizationName
Good evening
mitk::BaseApplication can't set OrganizationName if getQApplication will be
used before run()
It's very complicated behaviour but I will try to explain how to reproduce it:
To use QtSingleApplication I set myApp.setSingleMode(true); this way it will
create QtSingleApplication but there actually more things that I wanted to do
with it: I've added methods alike isRunning and sendMessage - and I need to use
it before qApp will be created because if qApp will be created I actually will
not even be able to get in there...
So if I call those methods by adding methods to BaseApplication alike:
void BaseApplication::sendMessage(const QByteArray msg)
{
QmitkSingleApplication* qCoreApp =
dynamic_cast<QmitkSingleApplication*>(this->getQApplication());
if (qCoreApp != nullptr)
{
qCoreApp->sendMessage(msg);
}
}
then qCoreApp is creating and when it does myApp.run doesn't have qApp on
initialize stage and then when initializeQt is called it gets out with : if
(qApp) return;
then my application ignore organization name and just creates it's folder in
AppData/local which breaks other logics...
How to deal with mitk::BaseApplication to be able to use isRunning and
sendMessage QtSingleApplication methods?
Thank you.
