<![CDATA[[Solved] Howto get the path part of a filename?]]>I have a (relative) filename for a file that doesn't yet exist.

Before I can create it, I have to make sure all the parent directories exist. QDir::mkpath should do that for me.

However, I cannot simply hand over the filename to mkpath. Instead, I have to hand over the path part of the filename, e.g. for 'home/test/mytest.png' the path part would be 'home/test'

Yet, I haven't found any method in QDir, QFile or QFileInfo that would return the path part from a either relative or absolute filename. Nor have I found a function that would allow me to remove the last level from a path/filename. Of course, I can resort to string manipulation, but I feel there should be something more path-aware doing that.

Have I missed something?

(Qt 4.8)

Edit: I was fooled into thinking that QFileInfo would require the file to exist.
