With Dynamic Property Overriders, it is possible to override the static font styles of the diagram labels.
The font styles belong to an Enumeration of the graphdesc meta-model.
Let's imagine in the school sample that we want to associate the font styles of the classrooms header label with their student count. For example, if the students count is > 0, we want a bold and underlined font style, and in other cases, we want an italic font.
To get this result, we have to :
-- if the classroom has at least one student if (students->size() > 0) then -- the header label is bold and underlined -- (we musn't forget to put the styles in a Collection, here -- we choose a Set) Set{ graphdesc::FontStyle::bold, graphdesc::FontStyle::underline } else -- else it is italic (in a Set like before) Set { graphdesc::FontStyle::italic } endif
You should get the following result (without the DPO on the left, and with the DPO on the right ; we can see the font styles that become dynamic on the right diagram) :
