.SH DESCRIPTION
The QFileIconProvider class provides icons for QFileDialog to use.
.PP
By default, QFileIconProvider is not used, but any application or library can subclass it, reimplement pixmap() to return a suitable icon, and make all QFileDialog objects use it by calling the static function QFileDialog::setIconProvider().
.PP
It's advisable to make all the icons QFileIconProvider returns be of the same size, or at least the same width. This makes the list view look much better.
.PP
See also: QFileDialog.

.SH "const QPixmap * QFileIconProvider::pixmap ( const QFileInfo & ) \fC[virtual]\fR"
