Struct qt_gui::QIconEnginePlugin

#[repr(C)]
pub struct QIconEnginePlugin { /* fields omitted */ }

The QIconEnginePlugin class provides an abstract base for custom QIconEngine plugins.

C++ class: QIconEnginePlugin.

C++ documentation:

The QIconEnginePlugin class provides an abstract base for custom QIconEngine plugins.

The icon engine plugin is a simple plugin interface that makes it easy to create custom icon engines that can be loaded dynamically into applications through QIcon. QIcon uses the file or resource name's suffix to determine what icon engine to use.

Writing a icon engine plugin is achieved by subclassing this base class, reimplementing the pure virtual function create(), and exporting the class with the Q_PLUGIN_METADATA() macro.

The json metadata should contain a list of icon engine keys that this plugin supports. The keys correspond to the suffix of the file or resource name used when the plugin was created. Keys are case insensitive.

{ "Keys": [ "myiconengine" ] }

Methods

impl QIconEnginePlugin

pub unsafe fn create_1a(
    &mut self,
    filename: impl CastInto<Ref<QString>>
) -> MutPtr<QIconEngine>

Creates and returns a QIconEngine object for the icon with the given filename.

Calls C++ function: pure virtual QIconEngine* QIconEnginePlugin::create(const QString& filename = …).

C++ documentation:

Creates and returns a QIconEngine object for the icon with the given filename.

pub unsafe fn create_0a(&mut self) -> MutPtr<QIconEngine>

Creates and returns a QIconEngine object for the icon with the given filename.

Calls C++ function: pure virtual QIconEngine* QIconEnginePlugin::create().

C++ documentation:

Creates and returns a QIconEngine object for the icon with the given filename.

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

Calls C++ function: virtual const QMetaObject* QIconEnginePlugin::metaObject() const.

pub unsafe fn qt_metacall(
    &mut self,
    arg1: Call,
    arg2: c_int,
    arg3: impl CastInto<MutPtr<*mut c_void>>
) -> c_int

Calls C++ function: virtual int QIconEnginePlugin::qt_metacall(QMetaObject::Call arg1, int arg2, void** arg3).

pub unsafe fn qt_metacast(
    &mut self,
    arg1: impl CastInto<Ptr<c_char>>
) -> MutPtr<c_void>

Calls C++ function: virtual void* QIconEnginePlugin::qt_metacast(const char* arg1).

pub unsafe fn static_meta_object() -> Ref<QMetaObject>

Returns a reference to the staticMetaObject field.

pub unsafe fn tr(
    s: impl CastInto<Ptr<c_char>>,
    c: impl CastInto<Ptr<c_char>>,
    n: c_int
) -> CppBox<QString>

Calls C++ function: static QString QIconEnginePlugin::tr(const char* s, const char* c, int n).

pub unsafe fn tr_utf8(
    s: impl CastInto<Ptr<c_char>>,
    c: impl CastInto<Ptr<c_char>>,
    n: c_int
) -> CppBox<QString>

Calls C++ function: static QString QIconEnginePlugin::trUtf8(const char* s, const char* c, int n).

Trait Implementations

impl CppDeletable for QIconEnginePlugin

unsafe fn delete(&mut self)

Destroys the icon engine plugin.

Calls C++ function: virtual [destructor] void QIconEnginePlugin::~QIconEnginePlugin().

C++ documentation:

Destroys the icon engine plugin.

You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.
