◆ get_property_declarations()

template<typename T>
std::string cgv::gui::key_control< T >::get_property_declarations ( )
virtual

return a semicolon separated list of property declarations

return a semicolon separated list of property declarations of the form "name:type", by default an empty list is returned

of the form "name1:type1;name2:type2;...", by default an empty list is returned. The types should by consistent with the names returned by cgv::type::info::type_name::get_name. The default implementation extracts names and types from the self_reflect() method and the meta type information provided by the get_type() method.

bool cgv::gui::key_control< T >::get_void ( const std::string & property,
const std::string & value_type,
void * value_ptr )
virtual

abstract interface for the getter of a dynamic property.

abstract interface for the getter, by default it simply returns false

The default implementation uses the self_reflect() method to find a member with the given property as name. If not found, the get_void method returns false.

◆ handle()

template<typename T>
bool cgv::gui::key_control< T >::handle ( event & e)
virtual

overload and implement this method to handle events

Parameters
eto be handled event (use e.get_kind() to check event type)
Returns
return true for handled events and false otherwise. Other event handlers (e.g. parents) only receive unhandled events if false is returned

Implements cgv::gui::event_handler.

◆ self_reflect()

template<typename T>
bool cgv::gui::key_control< T >::self_reflect ( cgv::reflect::reflection_handler & )
virtual

used for simple self reflection

is used by default implementation of set_void, get_void and get_property_declarations

The overloaded implementation is used by the default implementations of set_void, get_void and get_property_declarations with corresponding reflection handlers. The default implementation of self_reflect is empty.

virtual

abstract interface for the setter of a dynamic property.

abstract interface for the setter, by default it simply returns false
