|

| 90 | \brief The QInputContextFactory class creates QInputContext objects.
|
---|
| 91 |
|
---|
| 92 |
|
---|
| 93 | The input context factory creates a QInputContext object for a
|
---|
| 94 | given key with QInputContextFactory::create().
|
---|
| 95 |
|
---|
| 96 | The input contexts are either built-in or dynamically loaded from
|
---|
| 97 | an input context plugin (see QInputContextPlugin).
|
---|
| 98 |
|
---|
| 99 | keys() returns a list of valid keys. The
|
---|
| 100 | keys are the names used, for example, to identify and specify
|
---|
| 101 | input methods for the input method switching mechanism. The names
|
---|
| 102 | have to be consistent with QInputContext::identifierName(), and
|
---|
| 103 | may only contain ASCII characters.
|
---|
| 104 |
|
---|
| 105 | A key can be used to retrieve the associated input context's
|
---|
| 106 | supported languages using languages(). You
|
---|
| 107 | can retrieve the input context's description using
|
---|
| 108 | description() and finally you can get a user
|
---|
| 109 | friendly internationalized name of the QInputContext object
|
---|
| 110 | specified by the key using displayName().
