@short An abstract base class for asynchronous signing

To use a SignJob, first obtain an instance from the CryptoBackend

|
implementation, connect the progress() and result() signals to
|
|
|
|
|
|
suitable slots and then start the signing with a call to

|
|
|
|
start(). This call might fail, in which case the SignJob instance
|
|
|
|
|
|
will have scheduled it's own destruction with a call to
|
|
|
|
|
|
TQObject::deleteLater().
|
|
|
|
|
|
|
|
|
|
|
|
After result() is emitted, the SignJob will schedule it's own
|
|
|
|
|
|
destruction by calling TQObject::deleteLater().
