Public Attributes | |
| qmlbind_client_object *(* | new_object )(qmlbind_client_class *classRef, qmlbind_signal_emitter *signalEmitter) |
creates a new qmlbind_client_object to be used in QML. More... | |
| void(* | delete_object )(qmlbind_client_object *object) |
deletes a qmlbind_client_object that was created by new_object. | |
| qmlbind_value *(* | call_method )(qmlbind_engine *engine, qmlbind_client_object *object, const char *name, int argc, const qmlbind_value *const *argv) |
executes the name method defined on the qmlbind_client_object, with argc parameters in argv, and returns the result. More... | |
| qmlbind_value *(* | get_property )(qmlbind_engine *engine, qmlbind_client_object *object, const char *name) |
returns the value of the name property of the object C object. Ownership must be transferred to the caller. More... | |
| void(* | set_property )(qmlbind_engine *engine, qmlbind_client_object *object, const char *name, const qmlbind_value *value) |
sets the value of the name property to of the object C object to value. More... | |
encapsulates client-side functions that are used from QML for C object creation, destruction, method calls and property modification.
Those functions need to be implemented by libqmlbind's users for qmlbind_client_objects they want to expose to QML.
This struct is needed to construct new qmlbind_exporters. All function pointers need to be defined, a nullptr is not a valid value here.
| qmlbind_client_object*(* qmlbind_client_callbacks::new_object) (qmlbind_client_class *classRef, qmlbind_signal_emitter *signalEmitter) |
creates a new qmlbind_client_object to be used in QML.
qmlbind_client_callbacks hands over the qmlbind_client_object returned from this function as object to call_method(), get_property() and set_property().
| classRef | the qmlbind_client_class value that was given to qmlbind_exporter_new. Does not transfer ownership. |
| signalEmitter | should be stored in the returned object to be able to emit signals. Ownership is transfered. |
| qmlbind_value*(* qmlbind_client_callbacks::call_method) (qmlbind_engine *engine, qmlbind_client_object *object, const char *name, int argc, const qmlbind_value *const *argv) |
executes the name method defined on the qmlbind_client_object, with argc parameters in argv, and returns the result.
If the method does not return a value, call_method() should return qmlbind_value_new_undefined().
Ownership of the result must be transfered to the caller.
Ownership of engine and object is not transfered.
engine is intended to be used to create new objects or arrays.
| qmlbind_value*(* qmlbind_client_callbacks::get_property) (qmlbind_engine *engine, qmlbind_client_object *object, const char *name) |
returns the value of the name property of the object C object. Ownership must be transferred to the caller.
In case the name property does not exist, you should return a qmlbind_value_new_undefined().
Ownership of engine and object is not transfered.
engine is intended to be used to create new objects or arrays.
| void(* qmlbind_client_callbacks::set_property) (qmlbind_engine *engine, qmlbind_client_object *object, const char *name, const qmlbind_value *value) |
sets the value of the name property to of the object C object to value.
Ownership of engine and object is not transfered.
engine is intended to be used to create new objects or arrays.
