Member Function Documentation

bool QFontDialog::eventFilter ( QObject * o, QEvent * e ) [virtual protected]

Event filter to make up, down, pageup and pagedown work correctly in the line edits.

Reimplemented from QObject.

QListBox * QFontDialog::familyListBox () const [protected]

Returns a pointer to the "font family" list box. This is usable mainly if you reimplement updateFontFamilies();.

void QFontDialog::fontHighlighted ( const QFont & ) [signal]

This signal is emitted, when the user changed a setting in the dialog.

void QFontDialog::fontSelected ( const QFont & ) [signal]

This signal is emitted, when the user has chosen a font and clicked ok.

QFont QFontDialog::getFont ( bool * ok, QWidget * parent = 0,const char * name = 0 ) [static]

Opens a modal font dialog and returns the font selected by the user.

The ok parameter is set to TRUE if the user clicked OK, and FALSE if the user clicked Cancel.

If the user clicks Cancel the Qt default font is returned.

This static function is less capable than the full QFontDialog object, but is convenient and easy to use.

Example:

    // start at the current working directory and with *.cpp as filter
    bool ok;
    QFont f = QFontDialog::getFont( &ok, this );
    if ( ok ) {
        // the user selected a valid font
    } else {
        // the user cancelled the dialog
    }

QFont QFontDialog::getFont ( bool * ok, const QFont & initial, QWidget * parent = 0, const char * name = 0 ) [static]

Opens a modal font dialog and returns the font selected by the user.

initial is the initial selected font.

The ok parameter is set to TRUE if the user clicked OK, and FALSE if the user clicked Cancel.

If the user clicks Cancel the initial font is returned.

This static function is less capable than the full QFontDialog object, but is convenient and easy to use.

Example:

    // start at the current working directory and with *.cpp as filter
    bool ok;
    QFont f = QFontDialog::getFont( &ok, QFont( "Times", 12 ), this );
    if ( ok ) {
        // the user selected a valid font
    } else {
        // the user cancelled the dialog
    }

Another example:

    mywidget.setFont( QFontDialog::getFont( 0, mywidget.font() ) );

QComboBox * QFontDialog::scriptCombo () const [protected]

Returns a pointer to the "font style" list box. This is usable mainly if you reimplement updateFontStyles();.

This slot is called if the user changes the font size.

QListBox * QFontDialog::sizeListBox () const [protected]

Returns a pointer to the "font size" list box. This is usable mainly if you reimplement updateFontSizes();.

QListBox * QFontDialog::styleListBox () const [protected]

Returns a pointer to the "font style" list box. This is usable mainly if you reimplement updateFontStyles();.
