|

| 34 | \brief The QScriptClassPropertyIterator class provides an iterator interface for custom Qt Script objects.
|
|---|
| 35 |
|
|---|
| 36 | \ingroup script
|
|---|
| 37 |
|
|---|
| 38 | This class is only relevant if you have subclassed QScriptClass and
|
|---|
| 39 | want to provide enumeration of your custom properties (e.g. when
|
|---|
| 40 | objects of your class are used with QScriptValueIterator, or with
|
|---|
| 41 | the for-in statement in scripts).
|
|---|
| 42 |
|
|---|
| 43 | The object() function returns the Qt Script object the iterator is
|
|---|
| 44 | traversing.
|
|---|
| 45 |
|
|---|
| 46 | toFront(), hasNext() and next() provide forward iteration.
|
|---|
| 47 |
|
|---|
| 48 | toBack(), hasPrevious() and previous() provide backward iteration.
|
|---|
| 49 |
|
|---|
| 50 | name(), id() and flags() return information about the last property
|
|---|
| 51 | that was jumped over using next() or previous().
