\brief The QScreenDriverPlugin class is an abstract base class for
|
|
54 |
screen driver plugins in Qt for Embedded Linux.
|
|
55 |
|
|
56 |
Note that this class is only available in \l{Qt for Embedded Linux}.
|
|
57 |
|
|
58 |
\l{Qt for Embedded Linux} provides ready-made drivers for several screen
|
|
59 |
protocols, see the \l{Qt for Embedded Linux Display Management}{display
|
|
60 |
management} documentation for details. Custom screen drivers can be
|
|
61 |
implemented by subclassing the QScreen class and creating a screen
|
|
62 |
driver plugin.
|
|
63 |
|
|
64 |
A screen driver plugin can be created by subclassing
|
|
65 |
QScreenDriverPlugin and reimplementing the pure virtual keys() and
|
|
66 |
create() functions. By exporting the derived class using the
|
|
67 |
Q_EXPORT_PLUGIN2() macro, The default implementation of the
|
|
68 |
QScreenDriverFactory class will automatically detect the plugin
|
|
69 |
and load the driver into the server application at run-time. See
|
|
70 |
\l{How to Create Qt Plugins} for details.
