Hi Aida,
I found an easier method to get what you need. Once the
UpdateOutput() is called from your processor, and before adding your
data to the rendering tree, remove the property "levelwindow" from the
rendering node. Then, the level window property will be computed again
automatically:
1. In your panel widget, you need to disable the default output
processor observer (if any):
void SandboxPlugin::ResamplePanelWidget::OnInit( )
{
if ( GetProcessorOutputObserver( 0 ).IsNotNull( ) )
{
GetProcessorOutputObserver( 0 )->SetEnable( false );
}
}
2. In your panel widget, you need to overwrite the function
OnModifiedOutput():
void SandboxPlugin::ResamplePanelWidget::OnModifiedOutput( int num )
{
try
{
mitk::DataTreeNode::Pointer node;
Core::CastAnyProcessingData( GetRenderingTree( )->GetNode(
m_Processor->GetOutputDataEntity( 0 ) ), node );
if ( node.IsNotNull( ) &&
m_Processor->GetOutputDataEntity( 0 )->GetMTime( ) >
m_Processor->GetOutputDataEntity( 0 )->GetRenderingData( "MITK"
)->GetMTime( ) )
{
node->SetVisibility( false );
node->GetPropertyList( )->DeleteProperty( "levelwindow"
);
}
Core::DataTreeHelper::PublishOutput(
m_Processor->GetOutputDataEntityHolder( 0 ), GetRenderingTree( ) );
}
coreCatchExceptionsReportAndNoThrowMacro(
"ResamplePanelWidget::OnModifiedInput" );
}
Best regards,
Xavi
