Hi Daniel,
long time no see ;-)
Hi Sascha,
that's true, but it is a pleasure to be working with/on MITK again!
Thank you for your explanations, this summarizes very well what is
happening in the code. I actually did not see the sorting of MIME types
in the first place, this is a bit hidden by using a (sorting) std::set.
Also, I did not see that you can/should register a custom MIME type as a
service which can have a ranking property.
Providing a custom MIME type with higher ranking is working fine. My
custom image type is now getting selected by default in the "Save.." dialog.
For others who might be trying to give more weight to their custom data
type writers, here is a code summary of how to achieve this in your
module activator (assuming your custom writer is in a module):
us::ServiceProperties mimeTypeProperties;
mimeTypeProperties[us::ServiceConstants::SERVICE_RANKING()] =
1; // just bigger than 0
// MySpecialBaseDataWriterprovides a GetCustomMimeType() method
which returns
// a CustomMimeType describing the type, file extensions etc.
// The module activator holds one instance of this
CustomMimeType as a service instance
mitk::CustomMimeType* m_MimePrototype = new
mitk::CustomMimeType( MySpecialBaseDataWriter::GetCustomMimeType() );
context->RegisterService( m_MimePrototype, mimeTypeProperties);
// _with_ properties!
Again, thanks a lot for the explanations!
Best,
Daniel
