• close #17

Main window (built from a ui file) adds additional content from another ui file. Application uses the menu bar and provides an About ... dialog (modeless).

The About box has two pushbuttons that launch a web browser to show a specific URL. A third pushbutton brings up a new dialog showing the full text of the software license.
