|
|---|
| 59 | The QMetaObject class contains meta information about Qt objects.
|
|---|
| 60 | <p>
|
|---|
| 61 | <p> The Meta Object System in Qt is responsible for the signals and
|
|---|
| 62 | slots inter-object communication mechanism, runtime type
|
|---|
| 63 | information and the property system. All meta information in Qt is
|
|---|
| 64 | kept in a single instance of QMetaObject per class.
|
|---|
| 65 | <p> This class is not normally required for application programming.
|
|---|
| 66 | But if you write meta applications, such as scripting engines or
|
|---|
| 67 | GUI builders, you might find these functions useful:
|
|---|
| 68 | <ul>
|
|---|
| 69 | <li> <a href="#className">className</a>() to get the name of a class.
|
|---|
| 70 | <li> <a href="#superClassName">superClassName</a>() to get the name of the superclass.
|
|---|
| 71 | <li> <a href="#inherits">inherits</a>(), the function called by <a href="qobject.html#inherits">QObject::inherits</a>().
|
|---|
| 72 | <li> <a href="#superClass">superClass</a>() to access the superclass's <a href="metaobjects.html#meta-object">meta object</a>.
|
|---|
| 73 | <li> <a href="#numSlots">numSlots</a>(), <a href="#numSignals">numSignals</a>(), <a href="#slotNames">slotNames</a>(), and <a href="#signalNames">signalNames</a>() to get
|
|---|
| 74 | information about a class's signals and slots.
|
|---|
| 75 | <li> <a href="#property">property</a>() and <a href="#propertyNames">propertyNames</a>() to obtain information about a
|
|---|
| 76 | class's properties.
|
|---|
| 77 | </ul>
|
|---|
| 78 | <p> Classes may have a list of name-value pairs of class information.
|
|---|
| 79 | The number of pairs is returned by <a href="#numClassInfo">numClassInfo</a>(), and values are
|
|---|
| 80 | returned by <a href="#classInfo">classInfo</a>().
|
|---|
| 81 | <p> <p>See also <a href="moc.html">moc (Meta Object Compiler)</a> and <a href="objectmodel.html">Object Model</a>.
