Dear MITK team,
I was wondering if you would like to link the mitk progress bar to the
DICOM image reader, so the user can get a feedback on the progress
while opening a data set.
The code would be something like this:
// a progress command
itk::SmartPointer<ProgressCommandType> m_ProgressCommand;
m_ProgressCommand = ProgressCommandType::New();
m_ProgressCommand->SetCallbackFunction( this, &Navigator::OnITKProgressEvent );
// a progress callback
void OnITKProgressEvent(itk::Object *source, const itk::EventObject &)
{
// Get the value of the progress
float progress = reinterpret_cast<itk::ProcessObject
*>(source)->GetProgress();
// Update the progress bar and value in the MITK progress bar
m_mitkProgressMeter->value(100 * progress);
m_mitkOutProgressCounter->value(100 * progress);
// Show or hide progress bar if necessary
if(progress < 1.0f && !m_mitkProgressBar->visible())
{
m_mitkProgressBar->show();
}
else if (progress == 1.0f && m_mitkProgressBar->visible())
{
m_mitkProgressBar->hide();
}
}
// set the progress observer to the image reader
m_mitkImageReader->SetProgressCallback( m_ProgressCommand );
// In the mitk Image reader
typedef itk::ImageSeriesReader< ImageType > ImageSeriesReaderType;
typedef itk::ImageFileReader< ImageType > ImageReaderType;
/** Internal itkImageSeriesReader */
typename ImageSeriesReaderType::Pointer m_ImageSeriesReader;
typename ImageReaderType::Pointer m_ImageFileReader;
void SetProgressCallback(itk::Command *progressCallback)
{
m_ImageSeriesReader->AddObserver(itk::ProgressEvent(),progressCallback);
}
thanks,
sebastian
