I have a resource file which contains a few images. I'm using an external library which asks for path to the file in its constructor. I need to give it to the constructor, but I don't know how can I extract the path from resource file, not the
:/images/bubble.jpg, but/home/john/Pictures/bubble.jpg. I tried to use the next variant:QFileInfo image(":/images/bubble.jpg"); QString imagePath = image.absoluteFilePath();But it returns the
resource filepath -:/images/blah-blah.Maybe it's possible to create folder within the project and use something like:
QString imagePath = "$PROJECT_DIR" + "/images/bubble.png"But I couldn't find the appropriate variable. I tried to use
getenv()as well asqgetenv- got nothing. I know there's aqmakevariable called$$_PRO_FILE_PWD_which returns the folder with.profile, but I didn't figure out how to useqmakevariable.What can be the solution to this problem? Not necessarily that it would be a completely different one, it's ok. I just need to be able to have a folder within the project where I can store images and get the absolute path of each file.

@sosun
hmm, the resource file is compiled into the application.
So are you sure an external library can load it from the exe ressources ?QCoreApplication::applicationDirPath()
can tell where you exe is run from and you can construct a full path to image folder using that.
Please notice that you will need a copy of the image folder to the build directory as that is where your exe is being run from until deployment.also see

@mrjj Yeah, it works! Also, in the
releaseversion it will seek for the image not in thebuilddir, but in the primary folder of the project, am I right?@sosun
well if run from inside the IDE / creator, and it is set to release mode, it will run from the release folder. as far as i know. just like the debug folder.If you copy the exe file to another folder and run it there , then it will be that folder.
