|
|---|
| 72 | \brief The QMouseDriverFactory class creates mouse drivers in
|
|---|
| 73 | Qt for Embedded Linux.
|
|---|
| 74 |
|
|---|
| 75 | Note that this class is only available in \l{Qt for Embedded Linux}.
|
|---|
| 76 |
|
|---|
| 77 | QMouseDriverFactory is used to detect and instantiate the
|
|---|
| 78 | available mouse drivers, allowing \l{Qt for Embedded Linux} to load the
|
|---|
| 79 | preferred driver into the server application at runtime. The
|
|---|
| 80 | create() function returns a QWSMouseHandler object representing
|
|---|
| 81 | the mouse driver identified by a given key. The valid keys
|
|---|
| 82 | (i.e. the supported drivers) can be retrieved using the keys()
|
|---|
| 83 | function.
|
|---|
| 84 |
|
|---|
| 85 | \l{Qt for Embedded Linux} provides several built-in mouse drivers. In
|
|---|
| 86 | addition, custom mouse drivers can be added using Qt's plugin
|
|---|
| 87 | mechanism, i.e. by subclassing the QWSMouseHandler class and
|
|---|
| 88 | creating a mouse driver plugin (QMouseDriverPlugin). See the
|
|---|
| 89 | \l{Qt for Embedded Linux Pointer Handling}{pointer handling}
|
|---|
| 90 | documentation for details.
