childAt()

int QAccessibleAbstractScrollArea::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.

navigate()

int QAccessibleAbstractScrollArea::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.

rect()

QRect QAccessibleAbstractScrollArea::rect ( int  child ) const

virtual

Returns the geometry of the object, or of the object's child if child is not 0.

The geometry is in screen coordinates.

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

All visual objects provide this information.

setText()

void QAccessibleAbstractScrollArea::setText ( Text  t, int  child, const QString &  text  )

virtual

Sets the text property t of the object, or of the object's child if child is not 0, to text.

Note that the text properties of most objects are read-only.

}

state()

QAccessible::State QAccessibleAbstractScrollArea::state ( int  child ) const

virtual

Returns the current state of the object, or of the object's child if child is not 0.

The returned value is a combination of the flags in the QAccessible::StateFlag enumeration.

All accessible objects have a state.

text()

QString QAccessibleAbstractScrollArea::text ( Text  t, int  child  ) const

virtual

Returns the value of the text property t of the object, or of the object's child if child is not 0.

The Name is a string used by clients to identify, find, or announce an accessible object for the user. All objects must have a name that is unique within their container. The name can be used differently by clients, so the name should both give a short description of the object and be unique.

An accessible object's Description provides textual information about an object's visual appearance. The description is primarily used to provide greater context for vision-impaired users, but is also used for context searching or other applications. Not all objects have a description. An "OK" button would not need a description, but a tool button that shows a picture of a smiley would.

The Value of an accessible object represents visual information contained by the object, e.g. the text in a line edit. Usually, the value can be modified by the user. Not all objects have a value, e.g. static text labels don't, and some objects have a state that already is the value, e.g. toggle buttons.

The Help text provides information about the function and usage of an accessible object. Not all objects provide this information.

The Accelerator is a keyboard shortcut that activates the object's default action. A keyboard shortcut is the underlined character in the text of a menu, menu item or widget, and is either the character itself, or a combination of this character and a modifier key like Alt, Ctrl or Shift. Command controls like tool buttons also have shortcut keys and usually display them in their tooltip.

All objects provide a string for Name .
