Detailed Description

The QFontDialog class provides a dialog widget for selecting a font.

A font dialog is created through one of the static getFont() functions.

Examples:

 bool ok;
 QFont font = QFontDialog::getFont(
                 &ok, QFont("Helvetica [Cronyx]", 10), this);
 if (ok) {
     // the user clicked OK and font is set to the font the user selected
 } else {
     // the user canceled the dialog; font is set to the initial
     // value, in this case Helvetica [Cronyx], 10
 }

The dialog can also be used to set a widget's font directly:

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

If the user clicks OK the font they chose will be used for myWidget, and if they click Cancel the original font is used.

A font dialog in the Plastique widget style.

Member Type Documentation

enum QFontDialog::FontDialogOption
flags QFontDialog::FontDialogOptions

This enum specifies various options that affect the look and feel of a font dialog.

ConstantValueDescription
QFontDialog::NoButtons0x00000001Don't display OK and Cancel buttons. (Useful for "live dialogs".)
QFontDialog::DontUseNativeDialog0x00000002Use Qt's standard font dialog on the Mac instead of Apple's native font panel. (Currently, the native dialog is never used, but this is likely to change in future Qt releases.)

The FontDialogOptions type is a typedef for QFlags<FontDialogOption>. It stores an OR combination of FontDialogOption values.

See also options, setOption(), and testOption().


Property Documentation

currentFont : QFont

Access functions:

options : FontDialogOptions

This property holds the various options that affect the look and feel of the dialog.

By default, all options are disabled.

Options should be set before showing the dialog. Setting them while the dialog is visible is not guaranteed to have an immediate effect on the dialog (depending on the option and on the platform).

Access functions:

See also setOption() and testOption().


Member Function Documentation

QFontDialog::QFontDialog ( QWidget * parent = 0 )

Constructs a standard font dialog.

Use setCurrentFont() to set the initial font attributes.

The parent parameter is passed to the QDialog constructor.

This function was introduced in Qt 4.5.

See also getFont().

QFontDialog::QFontDialog ( const QFont & initial, QWidget * parent = 0 )

###

This function was introduced in Qt 4.5.

void QFontDialog::currentFontChanged ( const QFont & font )   [signal]

void QFontDialog::done ( int result )   [virtual protected]

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

QFont QFontDialog::getFont ( bool * ok, const QFont & initial, QWidget * parent, const QString & title, FontDialogOptions options )   [static]

Executes a modal font dialog and returns a font.

If the user clicks OK, the selected font is returned. If the user clicks Cancel, the initial font is returned.

The dialog is constructed with the given parent. title is shown as the window title of the dialog and initial is the initially selected font. If the ok parameter is not-null, the value it refers to is set to true if the user clicks OK, and set to false if the user clicks Cancel.

Examples:

 bool ok;
 QFont font = QFontDialog::getFont(&ok, QFont("Times", 12), this);
 if (ok) {
     // font is set to the font the user selected
 } else {
     // the user canceled the dialog; font is set to the initial
     // value, in this case Times, 12.
 }

The dialog can also be used to set a widget's font directly:

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

In this example, if the user clicks OK the font they chose will be used, and if they click Cancel the original font is used.

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

This is an overloaded member function, provided for convenience.

Call getFont(ok, initial, parent) instead.

The name parameter is ignored.

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

This is an overloaded member function, provided for convenience.

Call getFont(ok, parent) instead.

The name parameter is ignored.

QFont QFontDialog::getFont ( bool * ok, const QFont & initial, QWidget * parent, const QString & title )   [static]

This is an overloaded member function, provided for convenience.

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

This is an overloaded member function, provided for convenience.

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

This is an overloaded member function, provided for convenience.

Executes a modal font dialog and returns a font.

If the user clicks OK, the selected font is returned. If the user clicks Cancel, the Qt default font is returned.

The dialog is constructed with the given parent. If the ok parameter is not-null, the value it refers to is set to true if the user clicks OK, and false if the user clicks Cancel.

Example:

 bool ok;
 QFont font = QFontDialog::getFont(&ok, this);
 if (ok) {
     // font is set to the font the user selected
 } else {
     // the user canceled the dialog; font is set to the default
     // application font, QApplication::font()
 }

void QFontDialog::open ()

void QFontDialog::open ( QObject * receiver, const char * member )

This is an overloaded member function, provided for convenience.

###

QFont QFontDialog::selectedFont () const

###

void QFontDialog::setOption ( FontDialogOption option, bool on = true )

Sets the given option to be enabled if on is true; otherwise, clears the given option.

See also options and testOption().

bool QFontDialog::testOption ( FontDialogOption option ) const

Returns true if the given option is enabled; otherwise, returns false.

See also options and setOption().
