get the real path of a resource file

[szisziszilvi]

Hi,

is it possible to get the real path of a file that is added to the project with Qt's resource system?

Namely I have "test.qrc" added to the project and a file in that that can be referred with ":/res/file.txt" but this is of course not the real path in the file system. Now the class QFile can handle with the problem (would be dissapointing otherwise... ) but I can't give this string for example to an std::ifstream or it is not enough information for otput logs etc.

I don't know whether this works, but it just might:
QDir::absoluteFilePath ( const QString & fileName )

Resources are compiled in the executable (or exits as external binary file containing ALL files specified in QRC). So I don't think that You can use this with standard file system mechanism.

I tried QFileINfo's absoluteFilePath, but it returns also :/res/file.txt
I have the bad feeling that unfortunatelly Lesiok is right.

Lesiok is absolutely right. There is no file on the (deployed) file system corresponding to ":/res/file.txt". If you need that the be the case then don't use the resources system, or copy the data from the resource system to a dynamically allocated temporary file for external consumption.
