Seems like it's not so straigthforward as one could imagine..

#include <QtGui>
 
int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
 
	// create an example combo
	QComboBox combo;
	QStringList items;
	for (int i = 0; i < 10; ++i)
		items << QString::number(i);
	combo.addItems(items);
 
	// align the line edit
	combo.setEditable(true);
	combo.lineEdit()->setAlignment(Qt::AlignHCenter);
	// combo.lineEdit()->setReadOnly(true);
 
	// align items
	for (int i = 0; i < combo.count(); ++i)
	{
		combo.setItemData(i, Qt::AlignHCenter, Qt::TextAlignmentRole);
	}
	combo.show();
 
    a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
}

#include <QtGui>

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);

	// create an example combo
	QComboBox combo;
	QStringList items;
	for (int i = 0; i < 10; ++i)
		items << QString::number(i);
	combo.addItems(items);

	// align the line edit
	combo.setEditable(true);
	combo.lineEdit()->setAlignment(Qt::AlignHCenter);
	// combo.lineEdit()->setReadOnly(true);

	// align items
	for (int i = 0; i < combo.count(); ++i)
	{
		combo.setItemData(i, Qt::AlignHCenter, Qt::TextAlignmentRole);
	}
	combo.show();

    a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
    return a.exec();
}

To copy to clipboard, switch view to plain text mode

Hi,
I have a similar problem, but with a non editable combobox. The list of items is correclty centered, but since there is no lineEdit in a non editable combo box, I can't recenter the currently selected item. Any idea ? Thx !

Ok, just found the solution. Like jpn posted above, you _must_ have your combobox configured with setEditable(true), but you then you have to disable user input by setting the lineEdit to read-only. Thx jpn !
