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;
&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.

Enumerations

◆ FontDialogOption

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

Since
4.5
  • NoButtons Don't display OK and Cancel buttons. (Useful for "live dialogs".)
  • DontUseNativeDialog Use 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.)

◆ fontSelected

void QFontDialog::fontSelected ( const QFont font)
signal

This signal is emitted when a font has been selected.

◆ getFont() [1/4]

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 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.

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.

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.

◆ getFont() [4/4]

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

Executes a modal font dialog and returns a font.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

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;
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()
}

The signal will be disconnected from the slot when the dialog is closed.
