||
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. |
