Share Qt classes between two Qt app?
-
Imagining that I have two Qt apps running. The first one creates a Qt class QDir,for example:
QDir dir("/");
Can I send "dir" to another app?
Or how does another app access "dir"?

Hello,
When you want to share classes, you put them in a library (usually a dynamically loaded one) and export them from it. Each application then uses that library and the classes contained within,Kind regards.
0Even if we accept, as the basic tenet of true democracy, that one moron is equal to one genius, is it necessary to go a further step and hold that two morons are better than one genius?

Hi
To add to @kshegunov , if you want two apps to share data, you can also use
QSharedMemory as shown in the
Shared Memory Example
http://doc.qt.io/qt-5/qtcore-ipc-sharedmemory-example.htmlAlso, a low tech version could also be via
parameters
http://doc.qt.io/qt-5/qcommandlineparser.html
Even if one app is allowed to start the other.

Thanks. This tip seems useful.

I think the data is what is required to be shared. A library file won't help in this area without something elaborate going on inside (like QSharedMemory or equivalent).

Yes, I realized that after @mrjj's post but was reluctant to change my original comment after the fact.
