QgsProxyProgressTask, with the specified
QgsTaskshell which proxies progress reports.
Simple task shell which runs until finalized and reports progress only. This is usually used to expose a blocking operation’s progress via task manager.
New in version 3.4.
finalize(self, result: bool)¶
Finalizes the task, with the specified
This should be called when the operation being proxied has completed, to remove this proxy task from the task manager.
result (bool) –
finished(self, result: bool)¶
If the task is managed by a
QgsTaskManager, this will be called after the task has finished (whether through successful completion or via early termination). The result argument reflects whether the task was successfully completed or not. This method is always called from the main thread, so it is safe to create widgets and perform other operations which require the main thread. However, the GUI will be blocked for the duration of this method so tasks should avoid performing any lengthy operations here.
isCanceled(self) → bool¶
Trueif task should terminate ASAP. If the task reports the CanCancel flag, then derived classes’
run()methods should periodically check this and terminate in a safe manner.
isSignalConnected(self, QMetaMethod) → bool¶
receivers(self, PYQT_SIGNAL) → int¶
run(self) → bool¶
- Return type
sender(self) → QObject¶
senderSignalIndex(self) → int¶
setProgress(self, progress: float)¶
Sets the task’s current progress. The derived class should call this method whenever the task wants to update its progress. Calling will automatically emit the progressChanged signal.
progress – percent of progress, from 0.0 - 100.0
setProxyProgress(self, progress: float)¶
progress(from 0 to 100) for the proxied operation.
This method is safe to call from the main thread.
progress (float) –
