Question

In QT using QFileDialog’s getExistingDirectory, how can I start in a directory specified by an environment variable?

That is to say, how can I do this:

return QFileDialog::getExistingDirectory(0, "Open Directory", "%HOME%", QFileDialog::ShowDirsOnly);

Where %HOME% is the Windows Envirnment Variable to the user’s home usually found in C:\Users\UserName

Thanks.

The answer would probably be:

return QFileDialog::getExistingDirectory(0, "Open Directory", getenv("HOME"), QFileDialog::ShowDirsOnly);

getenv is declared in stdlib.h
