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.

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 Fusion widget style.

Member Typedef Documentation

Member Enumeration Documentation

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

ConstantValueDescription
QFontDialog::NoButtons 0x00000001 Do not display OK and Cancel buttons
QFontDialog::DontUseNativeDialog 0x00000002 Use the standard font dialog on the Mac instead of Apple's native font panel
See also
options, setOption(), testOption()

Constructor & Destructor Documentation

QFontDialog::QFontDialog ( QWidget parent = nullptr)
explicit

Constructs a standard font dialog. The parent object is passed to the QDialog constructor. Call setCurrentFont() to set the initial font attributes.

See also
getFont()
QFontDialog::QFontDialog ( const QFont initial,
QWidget parent = nullptr 
)
explicit

Constructs a standard font dialog with the given parent and specified initial font.

Method Documentation

void QFontDialog::changeEvent ( QEvent event)
overrideprotectedvirtual

Reimplemented from QWidget::changeEvent()

QFont QFontDialog::currentFont ( ) const

Returns the value of the currentFont property.

void QFontDialog::currentFontChanged ( const QFont font)
signal

This signal is emitted when the current font is changed. The new font is specified in font.

The signal is emitted while a user is selecting a font. Ultimately, the chosen font may differ from the font currently selected.

See also
currentFont, fontSelected(), selectedFont()
void QFontDialog::done ( int  result)
overrideprotected

Closes the dialog and sets its result code to result. If this dialog is shown with exec(), done() causes the local event loop to finish, and exec() to return result.

See also
QDialog::done()
void QFontDialog::fontSelected ( const QFont font)
signal

This signal is emitted when a font has been selected. The selected font is specified in font.

The signal is only emitted when a user has chosen the final font to be used. It is not emitted while the user is changing the current font in the font dialog.

See also
selectedFont(), currentFontChanged(), currentFont
QFont QFontDialog::getFont ( bool *  ok,
const QFont initial,
QWidget parent = nullptr,
const QString title = QString(),
FontDialogOptions  options = FontDialogOptions() 
)
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 and the options specified in options. 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.

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.

Warning
Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QFontDialog constructors.
QFont QFontDialog::getFont ( bool *  ok,
QWidget parent = nullptr 
)
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 CopperSpice 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.

bool ok;
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()
}
Warning
Do not delete parent during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the QFontDialog constructors.

QFontDialog::options

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

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).
