@jsulm thanx bro :)

just use the filePath without further modification, its already the complete path.
This code

QDir d = QFileInfo(filePath).absoluteDir(); QString absolute=d.absolutePath();

will lead you to the dir above the selected path...

Maybe there's a widget that you didn't put into a layout? The default position of such widget is in the upper left corner and the 100px sound like some default size.

Try adding this in your main:

qApp->setStyleSheet("QWidget { border: 2px solid red;}");

This should put a red frame around every widget so you'll see if anything's there.
