Information only widget could be shown in the information tab when specfied in the xml
In the .xml of a filter, one can use information only property to transfer information from the server to the client. However, showing these information requires either to use python or to use a dedicated property widget with some dummy non information property.
Adding an xml way to display these directly in the information tab would be nice, something like :
<IntVectorProperty command="GetNumberOfDomains" information_only="1" name="NumberOfDomains" panel_visibility="information"> <SimpleIntInformationHelper /> </IntVectorProperty>
