Constructors and Destructors

◆ QAccessibleStackedWidget()

QAccessibleStackedWidget::QAccessibleStackedWidget ( QWidget * widget )

explicit

Definition at line 458 of file qaccessiblewidgets.cpp.

     : QAccessibleWidgetEx(widget, LayeredPane)
 {
     Q_ASSERT(qobject_cast<QStackedWidget *>(widget));
 }

Functions

◆ childAt()

int QAccessibleStackedWidget::childAt	(	int	x,
		int	y
	)		const

virtual

Returns the 1-based index of the child that contains the screen coordinates (x, y).

This function returns 0 if the point is positioned on the object itself. If the tested point is outside the boundaries of the object this function returns -1.

This function is only relyable for visible objects (invisible object might not be laid out correctly).

All visual objects provide this information.

See also: rect()

Reimplemented from QAccessibleWidgetEx.

Definition at line 470 of file qaccessiblewidgets.cpp.

 {
     if (!stackedWidget()->isVisible())
         return -1;
     QWidget *currentWidget = stackedWidget()->currentWidget();
     if (!currentWidget)
         return -1;
     QPoint position = currentWidget->mapFromGlobal(QPoint(x, y));
     if (currentWidget->rect().contains(position))
         return 1;
     return -1;
 }

◆ childCount()

int QAccessibleStackedWidget::childCount ( ) const

virtual

Returns the number of children that belong to this object.

A child can provide accessibility information on its own (e.g. a child widget), or be a sub-element of this accessible object.

All objects provide this information.

See also: indexOfChild()

Reimplemented from QAccessibleWidgetEx.

Definition at line 483 of file qaccessiblewidgets.cpp.

 {
     return stackedWidget()->count();
 }

◆ indexOfChild()

int QAccessibleStackedWidget::indexOfChild ( const QAccessibleInterface * child ) const

virtual

Returns the 1-based index of the object child in this object's children list, or -1 if child is not a child of this object.

0 is not a possible return value.

All objects provide this information about their children.

See also: childCount()

Reimplemented from QAccessibleWidgetEx.

Definition at line 488 of file qaccessiblewidgets.cpp.

 {
     if (!child)
         return -1;
 
     QWidget* widget = qobject_cast<QWidget*>(child->object());
     int index = stackedWidget()->indexOf(widget);
     if (index >= 0) // one based counting of children
         return index + 1;
     return -1;
 }

◆ invokeMethodEx()

QVariant QAccessibleStackedWidget::invokeMethodEx	(	QAccessible::Method	method,
		int	child,
		const QVariantList &	params
	)

virtual

Reimplemented from QAccessibleWidgetEx.

Definition at line 464 of file qaccessiblewidgets.cpp.

 {
     return QVariant();
 }

◆ navigate()

int QAccessibleStackedWidget::navigate	(	RelationFlag	relation,
		int	index,
		QAccessibleInterface **	iface
	)		const

virtual

Navigates from this object to an object that has a relationship relation to this object, and returns the respective object in target.

It is the caller's responsibility to delete *target after use.

If an object is found, target is set to point to the object, and the index of the child of target is returned. The return value is 0 if target itself is the requested object. target is set to null if this object is the target object (i.e. the requested object is a handled by this object).

If no object is found target is set to null, and the return value is -1.

The entry parameter has two different meanings:

Hierarchical and Logical relationships – if multiple objects with the requested relationship exist entry specifies which one to return. entry is 1-based, e.g. use 1 to get the first (and possibly only) object with the requested relationship.

The following code demonstrates how to use this function to navigate to the first child of an object:

QAccessibleInterface *child = 0;
int targetChild = object->navigate(Accessible::Child, 1, &child);
if (child) {
// ...
delete child;
}
Geometric relationships – the index of the child from which to start navigating in the specified direction. entry can be 0 to navigate to a sibling of this object, or non-null to navigate within contained children that don't provide their own accessible information.

Note that the Descendent value for relation is not supported.

All objects support navigation.
