The TQGfxDriverPlugin class provides an abstract base for
TQt/Embedded graphics driver plugins.
< p >
< p > The graphics driver plugin is a simple plugin interface that makes
it easy to create custom graphics drivers.
< p > Writing a graphics driver plugin is achieved by subclassing this
base class, reimplementing the pure virtual functions < a href = "#keys" > keys< / a > () and
< a href = "#create" > create< / a > (), and exporting the class with the < tt > Q_EXPORT_PLUGIN< / tt >
macro. See the < a href = "plugins-howto.html" > Plugins
documentation< / a > for details.
< p > This class is only available in TQt/Embedded.
< p > See also < a href = "plugins.html" > Plugins< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQGfxDriverPlugin" > < / a > TQGfxDriverPlugin::TQGfxDriverPlugin ()
< / h3 >
Constructs a graphics driver plugin. This is invoked automatically
by the < tt > Q_EXPORT_PLUGIN< / tt > macro.
< h3 class = fn > < a name = "~TQGfxDriverPlugin" > < / a > TQGfxDriverPlugin::~TQGfxDriverPlugin ()
< / h3 >
Destroys the graphics driver plugin.
< p > You never have to call this explicitly. TQt destroys a plugin
automatically when it is no longer used.
< h3 class = fn > < a href = "qscreen.html" > TQScreen< / a > * < a name = "create" > < / a > TQGfxDriverPlugin::create ( const < a href = "ntqstring.html" > TQString< / a > & driver, int displayId )< tt > [pure virtual]< / tt >
< / h3 >
< p > Creates a driver matching the type specified by < em > driver< / em > , that
will use display < em > displayId< / em > .
< p > < p > See also < a href = "#keys" > keys< / a > ().
< h3 class = fn > < a href = "ntqstringlist.html" > TQStringList< / a > < a name = "keys" > < / a > TQGfxDriverPlugin::keys () const< tt > [pure virtual]< / tt >
< / h3 >
< p > Returns the list of graphics drivers this plugin supports.
< p > < p > See also < a href = "#create" > create< / a > ().
