QComboBox. Editable. Select all text and put cursor at the first Char of String

[PabloArg]

Maybe someone can help me with this. I need that my "QComboBox editable" is full selected and the cursor is positioned on the first character when it gets the focus.

Combination of:

combBox->setEditable(true)
combBox->lineEdit()->setCursorPosition(0);

Thanks michelson!!!
Just I want to add:

Don't forget to add this line, otherwise lineEdit() you can not use setCursorPosition(0):
#include <QLineEdit>
......
......

combBox->setEditable(true)
combBox->lineEdit()->setCursorPosition(0);
