Constructor & Destructor Documentation

Registry()

Registry::Registry ( QObject * parent = nullptr )

explicit

Construct a Registry object with parent as QObject parent.

Definition at line 14 of file registry.cpp.

~Registry()

Registry::~Registry ( )

override

Destroys this Registry.

Definition at line 20 of file registry.cpp.

Member Function Documentation

accessibleDescriptionChanged

void QAccessibleClient::Registry::accessibleDescriptionChanged ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted when an accessible description changes.

When subscribed to the PropertyChanged EventListener, this signal is emitted whenever the accessible-description property changes its value.

accessibleFromUrl

AccessibleObject Registry::accessibleFromUrl ( const QUrl & url ) const

slot

Creates the AccessibleObject for the url.

This can be used to deserialize an AccessibleObject after passing it around as string.

The returned QUrl returns a scheme of "accessibleobject".

Definition at line 60 of file registry.cpp.

accessibleNameChanged

void QAccessibleClient::Registry::accessibleNameChanged ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted when an accessible name changes.

When subscribed to the PropertyChanged EventListener, this signal is emitted whenever the accessible-name property changes its value.

added

void QAccessibleClient::Registry::added ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted if a AccessibleObject is created.

This signal indicates that the AccessibleObject instance was created and is going to be added/attached.

applications

QList< AccessibleObject > Registry::applications ( ) const

slot

List of all currently running applications that expose an accessibility interface.

Definition at line 55 of file registry.cpp.

childAdded

void QAccessibleClient::Registry::childAdded ( const QAccessibleClient::AccessibleObject & parent, int childIndex )

signal

Notifies about a new AccessibleObject.

The childAdded signal is emitted when a new accessible object is created. This signal depends on the implementation of the server side and is not reliable for all applications. The parameter childIndex is the index of the child that has been added.

See also

AccessibleObject::child(), childRemoved()

childRemoved

void QAccessibleClient::Registry::childRemoved ( const QAccessibleClient::AccessibleObject & parent, int childIndex )

signal

Notifies that an AccessibleObject has been removed.

The parameter childIndex is the index of the child that has been removed.

See also

AccessibleObject::child(), childAdded()

defunct

void QAccessibleClient::Registry::defunct ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted if a AccessibleObject is marked defunct.

This signal indicates that the AccessibleObject became invalid and does not point any longer to any valid accessible object.

enabledChanged

void QAccessibleClient::Registry::enabledChanged ( bool enabled )

signal

Emitted if the isEnabled state changed.

If the accessibility daemon got enabled or disabled either by us or ny someone else then this signal is emitted.

focusChanged

void QAccessibleClient::Registry::focusChanged ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted when the focus changed.

When subscribed to the Focus EventListener then this signal is emitted every time the focus changes. object is the newly focused AccessibleObject.

isEnabled

bool Registry::isEnabled ( ) const

slot

Returns true if the accessibility stack is enabled.

This means that an atspi registry daemon is running and available as org.a11y.bus at the session dbus. The org.a11y.bus implments the org.a11y.Status dbus interface that offers the IsEnabled property. The isEnabled and setEnabled methods do read/write the boolean value of that org.a11y.Status.IsEnabled dbus property..

Definition at line 25 of file registry.cpp.

isScreenReaderEnabled

bool Registry::isScreenReaderEnabled ( ) const

slot

Returns true if the screen reader is enabled.

This means that there is potentially a screen reader, if installed, that is enabled or disabled. This allows to enable system wide a screen reader with just one switch.

Definition at line 35 of file registry.cpp.

modelChanged

void QAccessibleClient::Registry::modelChanged ( const QAccessibleClient::AccessibleObject & object )

signal

Notifies that the object's table model changed.

removed

void QAccessibleClient::Registry::removed ( const QAccessibleClient::AccessibleObject & object )

signal

Emitted if a AccessibleObject is destroyed.

This signal indicates that the AccessibleObject instance was destroyed and ended its life-time.

screenReaderEnabledChanged

void QAccessibleClient::Registry::screenReaderEnabledChanged ( bool enabled )

signal

Emitted if the isScreenReaderEnabled state changed.

If the screen reader enabled property got enabled or disabled either by us or by someone else then this signal is emitted.

selectionChanged

void QAccessibleClient::Registry::selectionChanged ( const QAccessibleClient::AccessibleObject & object )

signal

Notifies that the object's selection changed.

setEnabled

void Registry::setEnabled ( bool enable )

slot

Activates accessibility when enabled and tells toolkits to provide updates such as focus changes.

Definition at line 30 of file registry.cpp.

setScreenReaderEnabled

void Registry::setScreenReaderEnabled ( bool enable )

slot

Tells the system that a screen reader is enabled.

Definition at line 40 of file registry.cpp.

stateChanged

void QAccessibleClient::Registry::stateChanged ( const QAccessibleClient::AccessibleObject & object, const QString & state, bool active )

signal

Notifies about a state change in an object.

The state of object has change. If the state is now set active is true, otherwise the state was removed.

subscribedEventListeners

Registry::EventListeners Registry::subscribedEventListeners ( ) const

slot

Returns the active event listeners.

Definition at line 50 of file registry.cpp.

subscribeEventListeners

void Registry::subscribeEventListeners ( const EventListeners & listeners ) const

slot

In order to get notified of changes in accessible applications it is neccessary to subscribe to the listeners that are relevant.

This will unsubscribe all previously subscribed event listeners.

Definition at line 45 of file registry.cpp.

textCaretMoved

void QAccessibleClient::Registry::textCaretMoved ( const QAccessibleClient::AccessibleObject & object, int pos )

signal

Emitted when the text cared moved.

When subscribed to the TextCaretMoved EventListener then this signal is emitted every time the caret in an accessible object that implements a text-interface (like QLineEdit, QTextArea and QComboBox) moved to another position.

textChanged

void QAccessibleClient::Registry::textChanged ( const QAccessibleClient::AccessibleObject & object, const QString & text, int startOffset, int endOffset )

signal

Emitted when an object's text was changed.

The new text will be text. The change starts at startOffset and goes to endOffset.

textInserted, textRemoved

textInserted

void QAccessibleClient::Registry::textInserted ( const QAccessibleClient::AccessibleObject & object, const QString & text, int startOffset, int endOffset )

signal

textInserted, textRemoved

textRemoved

void QAccessibleClient::Registry::textRemoved ( const QAccessibleClient::AccessibleObject & object, const QString & text, int startOffset, int endOffset )
