Color ComboBox

[spirit]

take a look at this example. I think it should help you.

Thanks for the reply. However, in this case the color only occupies a small rectangle in the left side of the combobox. I would like the color to occupy the whole of the combobox.

try this

QComboBox *cb = new QComboBox(this);
const QStringList colorNames = QColor::colorNames();
int index = 0;
foreach (const QString &colorName, colorNames) {
	const QColor color(colorName);
	cb->addItem(colorName, color);
	const QModelIndex idx = cb->model()->index(index++, 0);
	cb->model()->setData(idx, color, Qt::BackgroundColorRole);
}

QComboBox *cb = new QComboBox(this);
const QStringList colorNames = QColor::colorNames();
int index = 0;
foreach (const QString &colorName, colorNames) {
	const QColor color(colorName);
	cb->addItem(colorName, color);
	const QModelIndex idx = cb->model()->index(index++, 0);
	cb->model()->setData(idx, color, Qt::BackgroundColorRole);
}

hope you've got idea.
