set path with qmake and use it in the program

[sajis997]

Hello forum,

I want to declare a custom variable in qmake that contains the absolute path to some files. and later inside the application program i want to use the variable in qmake to get to the path and load the desired file i want to load.


Is that possible?

Any more reference example will be very helpful

Yes.

Now on to the question you really wanted to ask:

// *.pro
DEFINES += SOMEDIR=\\\"/some/full/path/\\\"
 
// *.cpp
QFile file(SOMEDIR "filename.ext");
// or
QDir path(SOMEDIR);
QString filePath = path.filePath("filename.ext");

// *.pro
DEFINES += SOMEDIR=\\\"/some/full/path/\\\"

// *.cpp
QFile file(SOMEDIR "filename.ext");
// or
QDir path(SOMEDIR);
QString filePath = path.filePath("filename.ext");

To copy to clipboard, switch view to plain text mode 

Hard coding paths like this is not advisable for anything other than tests IMHO.
