\class QStyleFactory qstylefactory.h
|

|
|
\brief The QStyleFactory class creates QStyle objects.
|
||
|
|
|
||
|
|
The style factory creates a QStyle object for a given key with
|
||
|
|
QStyleFactory::create(key).
|
||
|
|
|
||
|
|
The styles are either built-in or dynamically loaded from a style
|
||
|
|
plugin (see \l QStylePlugin).
|
||
|
|
|
||
|
|
QStyleFactory::keys() returns a list of valid keys, typically
|
||
|
|
including "Windows", "Motif", "CDE", "MotifPlus", "Platinum",
|
||
|
|
"SGI" and "Compact". Depending on the platform, "WindowsXP",
|
||
|
|
"Aqua" or "Macintosh" may be available.
