Hello, in order to implement the layout objects for my SoC project I need to
know if it would be possible to add size hints to Evas Objects.
I attached a patch file with the required changes. I tried following the
implementation of size hints since its a similar concept but I can't compile
the code.
I defined Evas_Fill_Policy type in Evas.h but I cannot use it in
evas_private.h. Even when it includes "Evas.h" I still get the error
message: "../../src/lib/include/evas_private.h:474: error: expected
specifier-qualifier-list before 'Evas_Fill_Policy'".
Than ks
