|

|
@short An abstract base class for asynchronous crypto operations
|
|
|
|
|
|
|
|
|
|
|
|
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.
