RFC: Data Recovery

Currently, we use our own passive notification bar to show a recovery bar when a swap file was found:

Since version 4.7 we have a class called KMessageWidget (api documentation). Using KMessageWidget, the notification could also look like this:

Imo, the new one looks nicer, as it much better distinguishes the notification popup from the rest of the ui. However, it several drawbacks:

  • the minimum width is now 800 pixel due to the label (too large, might break layout in apps)
  • the title “Data Recovery” was omitted
  • the “Help” link, showing a tool tip with further information, can not be added anymore (the api does not allow it)

Possible solutions:

  • put the buttons under the label, as it was in the old version (currently, the api does not allow it, so we’d need something like setButtonsUnderText(bool))
  • wrap the text in the label (looks aweful, since the buttons appear then between two lines of text)
  • to get the “Help” label back, the api would need to forward the QLabel’s signal linkActivated(const QString&)

I’m not sure whether the API can be extended in the 4.x line, though…
