QColorDialog::QColorDialog(QWidget *parent = nullptr)

Constructs a color dialog with the given parent.

This function was introduced in Qt 4.5.

QColorDialog::QColorDialog(const QColor &initial, QWidget *parent = nullptr)

Constructs a color dialog with the given parent and specified initial color.

This function was introduced in Qt 4.5.

[virtual] QColorDialog::~QColorDialog()

Destroys the color dialog.

[override virtual protected] void QColorDialog::changeEvent(QEvent *e)

Reimplemented from QWidget::changeEvent().

[signal] void QColorDialog::colorSelected(const QColor &color)

This signal is emitted just after the user has clicked OK to select a color to use. The chosen color is specified by color.

See also color and currentColorChanged().

[signal] void QColorDialog::currentColorChanged(const QColor &color)

This signal is emitted whenever the current color changes in the dialog. The current color is specified by color.

Note: Notifier signal for property currentColor.

See also color and colorSelected().

[static] QColor QColorDialog::customColor(int index)

Returns the custom color at the given index as a QColor value.

This function was introduced in Qt 4.5.

See also setCustomColor().

[static] int QColorDialog::customCount()

Returns the number of custom colors supported by QColorDialog. All color dialogs share the same custom colors.

[override virtual protected] void QColorDialog::done(int result)

Reimplemented from QDialog::done().

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().

[static] QColor QColorDialog::getColor(const QColor &initial = Qt::white, QWidget *parent = nullptr, const QString &title = QString(), QColorDialog::ColorDialogOptions options = ...)

Pops up a modal color dialog with the given window title (or "Select Color" if none is specified), lets the user choose a color, and returns that color. The color is initially set to initial. The dialog is a child of parent. It returns an invalid (see QColor::isValid()) color if the user cancels the dialog.

The options argument allows you to customize the dialog.

This function was introduced in Qt 4.5.

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

Opens the dialog and connects its colorSelected() signal to the slot specified by receiver and member.

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

This function was introduced in Qt 4.5.

QColor QColorDialog::selectedColor() const

Returns the color that the user selected by clicking the OK or equivalent button.

Note: This color is not always the same as the color held by the currentColor property since the user can choose different colors before finally selecting the one to use.

[static] void QColorDialog::setCustomColor(int index, QColor color)

Sets the custom color at index to the QColor color value.

Note: This function does not apply to the Native Color Dialog on the macOS platform. If you still require this function, use the QColorDialog::DontUseNativeDialog option.

See also customColor().

void QColorDialog::setOption(QColorDialog::ColorDialogOption 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().

[static] void QColorDialog::setStandardColor(int index, QColor color)

Sets the standard color at index to the QColor color value.

Note: This function does not apply to the Native Color Dialog on the macOS platform. If you still require this function, use the QColorDialog::DontUseNativeDialog option.

See also standardColor().

[override virtual] void QColorDialog::setVisible(bool visible)

Reimplemented from QDialog::setVisible().

Changes the visibility of the dialog. If visible is true, the dialog is shown; otherwise, it is hidden.

[static] QColor QColorDialog::standardColor(int index)

Returns the standard color at the given index as a QColor value.

This function was introduced in Qt 5.0.

See also setStandardColor().

bool QColorDialog::testOption(QColorDialog::ColorDialogOption option) const

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

This function was introduced in Qt 4.5.

See also options and setOption().
