Hi,
I do not know if this is really a bug, but I better tell you of it. It might
also be a fault of mine (sry).
I am writing my own cell renderer (inherited from CellRenderer) and want to
create a read only property, but it does not work.
Glib::Property< MultipleChoiceString > property_mcs_; // property declaration
Glib::PropertyProxy< MultipleChoiceString > property_mcs() { return
property_mcs_.get_proxy(); } // works
Glib::PropertyProxy_ReadOnly< MultipleChoiceString > property_mcs() const {
return property_mcs_.get_proxy(); } // error
The third line causes an error because calling get_proxy on the property does
not keep the property constant. Maybe, one should add a function for a Property
that returns a PropertyProxy_ReadOnly? How else could this problem be solved?
Thank you for answers in advance,
Johannes
