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.

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.

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:
Note that the Descendent
value for relation is not supported.
All objects support navigation.
Reimplemented from QAccessibleWidgetEx.
Definition at line 584 of file qaccessiblewidgets.cpp.
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.

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.
Reimplemented from QAccessibleWidgetEx.
Definition at line 548 of file qaccessiblewidgets.cpp.
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 .
