\brief The TQIconFactory class is used to create pixmaps for a QIconSet.
|
|
|
|
By reimplementing createPixmap(), you can override QIconSet's
|
|
default algorithm for computing pixmaps not supplied by the user.
|
|
|
|
Call setAutoDelete(TRUE) if you want the factory to automatically
|
|
delete itself when it is no longer needed by QIconSet.
