Hi all,
I am trying to do a progress bar in a filter. I did the following steps:
1- add an information only property to my xml to pass the progress
status to the client:
<IntVectorProperty
name="currentIteration"
command="GetcurrentIteration"
number_of_elements="1"
information_only="1"
default_values="0"
immediate_update="1">
<SimpleIntInformationHelper/>
</IntVectorProperty>
2 - connect this property to a slot in the client to update the
progress bar value:
this->currentIteration = vtkSMIntVectorProperty::SafeDownCast(
this->proxy()->GetProperty("currentIteration"));
this->QVTKConnect = vtkSmartPointer<vtkEventQtSlotConnect>::New();
this->QVTKConnect->Connect(currentIteration, vtkCommand::ModifiedEvent,
this, SLOT(updateProgressBar()),0,0, Qt::DirectConnection);
3- I update the value of the progress bar in the Slot:
void pqMyFilter::updateProgressBar()
{
this->progressBar->setValue(this->currentIteration->GetElement(0));
QCoreApplication::processEvents();
}
The value of the progress bar is updated only when requestData is
done. Is that mean the immediate_update of an
information only property doesn't work ?
Thank you !
