.SH DESCRIPTION
The QFontDialog provides a dialog widget for selecting a text font
.PP
Used for allowing the user to select a font among the available fonts on the underlying window system.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "bool QFontDialog::eventFilter ( QObject * o, QEvent * e ) \fC[virtual protected]\fR"
Event filter to make up, down, pageup and pagedown work correctly in the line edits.
.PP
Reimplemented from QObject.
.SH "QListBox * QFontDialog::familyListBox () const \fC[protected]\fR"
Returns a pointer to the "font family" list box. This is usable mainly if you reimplement updateFontFamilies();.
.SH "QFont QFontDialog::getFont ( bool * ok, QWidget * parent = 0,const char * name = 0 ) \fC[static]\fR"
Opens a modal font dialog and returns the font selected by the user.
.PP
The \fIok\fR parameter is set to TRUE if the user clicked OK, and FALSE if the user clicked Cancel.
.PP
If the user clicks Cancel the Qt default font is returned.
.PP
This static function is less capable than the full QFontDialog object, but is convenient and easy to use.
.PP
Example:
.PP
.nf
.br
    // start at the current working directory and with *.cpp as filter
.br
    bool ok;
.br
    QFont f = QFontDialog::getFont( &ok, this );
.br
    if ( ok ) {
.br
        // the user selected a valid font
.br
    } else {
.br
        // the user cancelled the dialog
.br
    }
.fi
.SH "QFont QFontDialog::getFont ( bool * ok, const QFont & initial, QWidget * parent = 0, const char * name = 0 ) \fC[static]\fR"
Opens a modal font dialog and returns the font selected by the user.
.PP
\fIinitial\fR is the initial selected font.
.PP
The \fIok\fR parameter is set to TRUE if the user clicked OK, and FALSE if the user clicked Cancel.
.PP
If the user clicks Cancel the \fIinitial\fR font is returned.
.PP
This static function is less capable than the full QFontDialog object, but is convenient and easy to use.
.PP
Example:
.PP
.nf
.br
    // start at the current working directory and with *.cpp as filter
.br
    bool ok;
.br
    QFont f = QFontDialog::getFont( &ok, QFont( "Times", 12 ), this );
.br
    if ( ok ) {
.br
        // the user selected a valid font
.br
    } else {
.br
        // the user cancelled the dialog
.br
    }
.fi

Another example:
.PP
.nf
.br
    mywidget.setFont( QFontDialog::getFont( 0, mywidget.font() ) );
.fi
.SH "QComboBox * QFontDialog::scriptCombo () const \fC[protected]\fR"
Returns a pointer to the "font style" list box. This is usable mainly if you reimplement updateFontStyles();.
.SH "QListBox * QFontDialog::sizeListBox () const \fC[protected]\fR"
Returns a pointer to the "font size" list box. This is usable mainly if you reimplement updateFontSizes();.
.SH "QListBox * QFontDialog::styleListBox () const \fC[protected]\fR"
Returns a pointer to the "font style" list box. This is usable mainly if you reimplement updateFontStyles();.
.SH "void QFontDialog::updateFamilies () \fC[virtual protected]\fR"
Update the contents of the "font family" list box. This function can be reimplemented if you have special requirements.
.SH "void QFontDialog::updateScripts () \fC[virtual protected]\fR"
Update the contents of the "font script" combo box. This function can be reimplemented if you have special requirements.
.SH "void QFontDialog::updateStyles () \fC[virtual protected]\fR"
Update the contents of the "font style" list box.  This
