Struct BitmapFontFile

pub struct BitmapFontFile(/* private fields */);

Font implementation for bitmap fonts. Supported bitmap fonts consist of a plain text fnt definition file and one or more bitmaps containing the pre-rendered glyphs at a certain size.

Methods from Deref<Target = Resource>

pub fn get_name(&self) -> Result<KanziString, Error>

Gets the resource name.

pub fn get_url(&self) -> Result<KanziString, Error>

Gets the resource URL. Note that the URL is not necessarily in URL form if resource has been just created.

Returns

URL string.

pub fn set_keep_alive(&self, keep_alive: bool) -> Result<(), Error>

Sets the keep alive flag. Can be set only before the resource is registered to the resource manager. Normally set by loadFromKZB.

Arguments

• keep_alive - Value for the keep alive flag.

Methods from Deref<Target = Object>

pub fn as_ptr(&self) -> *mut ObjectWrapper

pub fn as_wrapper(&self) -> &ObjectWrapper

pub fn as_object(&self) -> &Object

Represents any type inheriting from Object as &Object. This is useful for comparisions when PartialEq traits failed to compare objects of different types.

let child = screen.get_child(0)?;
let parent = child.get_parent()?.into_error(ErrorKind::ObjectNotFound)?;
// assert_eq!(screen, parent); // <- Fails to compile!
assert_eq!(screen.as_object(), parent.as_object());

pub fn get_native(&self) -> Result<NonNull<c_void>, Error>

Gets a pointer to the backing C++ instance.

pub fn is_stale(&self) -> bool

Checks whether the weak reference has expired.

pub fn get_property<T>( &self, property_type: &PropertyType<T>, ) -> Result<<T as VariantConstraint>::RetArg, Error>

where T: PropertyTypeConstraint,

Returns the current value of a property disregarding modifiers.

Base value is affected by the following inputs where the highest entry in the list determines the base value:

1. Local value set with setProperty or loaded from kzb
2. Value set by a style affecting the property.
3. Value defined by class metadata.

Modifiers are not applied, the highest-priority base value is returned.

If no inputs to the property value can be established the system returns the value default value from property type metadata.

Arguments

• property_type - The property type identifying the property to retrieve.

Returns

The evaluated property value.

pub fn get_optional_property<T>( &self, property_type: &PropertyType<T>, ) -> Result<Option<<T as VariantConstraint>::RetArg>, Error>

where T: PropertyTypeConstraint,

Returns the current value of a property disregarding modifiers, but does not default to the value in property metadata if there are no inputs to the property value.

If there is no value sources, None is returned.

If no inputs to the property value can be established the system returns the value default value from property type metadata.

Arguments

• property_type - The property type identifying the property to retrieve.

Returns

The evaluated property value.

pub fn set_property<T>( &self, property_type: &PropertyType<T>, value: <T as VariantConstraint>::DataArg<'_>, ) -> Result<(), Error>

where T: PropertyTypeConstraint,

Sets the local value of a property type.

pub fn has_value<T>( &self, property_type: &PropertyType<T>, ) -> Result<bool, Error>

where T: PropertyTypeConstraint,

Evaluates whether there are any inputs into the property value. Both value sources and modifiers are taken into account.

Returns

Returns true if there are inputs into the property value, false otherwise.

pub fn remove_local_value<T>( &self, property_type: &PropertyType<T>, ) -> Result<(), Error>

where T: PropertyTypeConstraint,

Removes the local value associated with the property.

pub fn get_metaclass(&self) -> Result<Metaclass, Error>

Returns the metaclass of the dynamic type of the object.

pub fn get_domain(&self) -> Result<Domain, Error>

Returns the domain the object belongs to.

pub fn set_flag_keep_during_patching<T>( &self, property_type: &PropertyType<T>, ) -> Result<(), Error>

where T: PropertyTypeConstraint,

Sets the flag to indicate that the property was loaded from KZB.

pub fn debug_string(&self) -> Result<String, Error>

Builds a string representation of the object intended for debugging purposes.
