- During the operation, you might receive progress updates through
- the progress() signal as they arrive, but an implementation is
- free to not send progress information. You should show a busy
- progressbar until the first progress() signal is received.
-
- The done() signal is emitted _before_ the result() signals of
- subclasses and should be used to hide and/or reset progress bars,
- not to learn of the end of the operation. Use the result()
- signals for that.
-
- To cancel the operation, simply call slotCancel(). The result()
- signal of subclasses will still be emitted, though, and will
- carry the information that the operation was canceled.
