Constructors and Destructors

◆ QAccessibleDockWidget()

Functions

◆ childAt()

int QAccessibleDockWidget::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.

1065  return i;
1066  }
1067  return -1;
1068 }
QRect rect(int child) const
Returns the geometry of the object, or of the object&#39;s child if child is not 0.
int childCount() const
Returns the number of children that belong to this object.

◆ childCount()

int QAccessibleDockWidget::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.

◆ navigate()

int QAccessibleDockWidget::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:

    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 QAccessibleDockWidget::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.
