Review request for KDE Utils, KDE Usability, Elvis Angelaccio, and Raphael Kubo da Costa.


Bugs: 201162
    http://bugs.kde.org/show_bug.cgi?id=201162


Repository: ark


Description
-------

Add an Open action, which opens an archive entry with the associated application. This was previously only possible through the "Open With" action, but this required several clicks. Currently, the Preview action is still the default, i.e. when the user clicks an archive entry the Preview action is called.

QSignalMapper is used to connect the signals from the Open, Open With and Preview actions to the same slot.

As for Preview, the file is extracted to a QTemporaryDir and then opened. The temporarily extracted file is monitored for changes using QFileSystemWatcher and on change a KMessageBox is opened to query the user if the archive should be updated with the modified file. If the user accepts slotAddFiles() is called.

The previously unimplemented path argument of slotAddFiles() is used to allow for updating a file in a subdirectory within the archive.

Things to consider:
1. Should the Open action be the default e.g. when clicking an entry, instead of Preview?
2. Currently, the action has the same visible name as the action for opening archives in the File menu. One of them should be renamed. Which one, and to what?
3. Should we set some keyboard shortcuts for "Open" and "Open With"? If yes, which?
