If you want to use multiple filters, separate each one with two semicolons. The openUrl knows how to open a file given the file name. If options includes the file dialog will treat symlinks as regular directories. Reading from a and writing to it is as simple as opening the stream - with the respective device as a parameter - and reading from or writing to it. If no files are selected, or the mode is not or , selectedFiles contains the current path in the viewport. Qt and respective logos are trademarks of The Qt Company Ltd.

As usual, you write a wrapper class for your QtDesigner code for the second dialog like you did with MyForm. The Qt designer will save you 100+ hours at least per any major project development, and then probably thousands in any major project over time.
