Einfügen eines LineEdits

Browse Source 
Einfügen von einem LineEdit oben im Widget, in das ein Dateipfad geschrieben werden kann. Alternativ kann über den Browse Button ein File Explorer geöffnet werden und in diesem die Datei ausgewählt werden. Der ausgewählte Dateipfad erscheint im LineEdit. Der Dateipfad im LineEdit kann über den Add Button in die Liste eingefügt werden. Nach betätigen des Add Buttons (nach wie vor Überprüfung, ob Dateipfad existiert und eventuell schon in Liste ist) wird das LineEdit geleert.
