QAccessibleObject Class

QAccessibleObject 类实现了 QObjectsQAccessibleInterface 的部分功能。更多

头文件: #include <QAccessibleObject>
CMake: find_package(Qt6 REQUIRED COMPONENTS Gui)
target_link_libraries(mytarget PRIVATE Qt6::Gui)
qmake: QT += gui
继承: QAccessibleInterface
继承于:

QAccessibleWidget

公共函数

QAccessibleObject(QObject *object)

重新实现的公共函数

virtual QAccessibleInterface *childAt(int x, int y) const override
virtual bool isValid() const override
virtual QObject *object() const override
virtual QRect rect() const override
virtual void setText(QAccessible::Text t, const QString &text) override

受保护函数

virtual ~QAccessibleObject()

详细说明

该类是QWidget 应用程序辅助功能的一部分。

提供该类主要是为了方便使用。QAccessibleInterface 的所有子类如果提供非 Widget 对象的实现,都应使用该类作为基类。

成员函数文档

[explicit] QAccessibleObject::QAccessibleObject(QObject *object)

object 创建一个 QAccessibleObject。

[virtual noexcept protected] QAccessibleObject::~QAccessibleObject()

销毁QAccessibleObject

只有调用 release() 将内部引用计数器递减为零时,才会发生这种情况。

[override virtual] QAccessibleInterface *QAccessibleObject::childAt(int x, int y) const

重实现:QAccessibleInterface::childAt(int x, int y) const.

[override virtual] bool QAccessibleObject::isValid() const

重实现:QAccessibleInterface::isValid() const.

[override virtual] QObject *QAccessibleObject::object() const

重实现:QAccessibleInterface::object() const.

[override virtual] QRect QAccessibleObject::rect() const

重实现:QAccessibleInterface::rect() const.

[override virtual] void QAccessibleObject::setText(QAccessible::Text t, const QString &text)

重实现:QAccessibleInterface::setText(QAccessible::Text t, const QString &text).
