Trait Implementations

impl Debug for QRCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QRCode

fn default() -> Self

impl DerivedObjectProperties for QRCode

fn derived_properties() -> &'static [ParamSpec]

Properties installed for this type.

fn derived_property(&self, id: usize, pspec: &ParamSpec) -> Value

Similar to ObjectImpl but auto-generated by the Properties macro to allow handling more complex use-cases.

fn derived_set_property(&self, id: usize, value: &Value, pspec: &ParamSpec)

Similar to ObjectImpl but auto-generated by the Properties macro to allow handling more complex use-cases.

impl ObjectImpl for QRCode

fn constructed(&self)

fn property(&self, id: usize, pspec: &ParamSpec) -> Value

Property getter.

fn signals() -> &'static [Signal]

Signals installed for this type.

fn dispose(&self)

Disposes of the object.

fn notify(&self, pspec: &ParamSpec)

Function to be called when property change is notified for with self.notify("property").

fn dispatch_properties_changed(&self, pspecs: &[ParamSpec])
