In PyQt4, I want to present a QPushButton that looks like the down-arrow button in QComboBox.  Feasible, and if so, how?
I don't need help getting my new widget-combination acting like a QComboBox (see below). I only want the QPushButton display/graphic to look like the down-arrow button in a QComboBox - and tips/code on how to overlay that graphic (especially if said graphic comes via a file) onto my own QPushButton.
More details, context:
I'm seeking to replace a QComboBox widget with a QLineEdit + QCalendarWidget, because QDateEdit isn't as customizable as I need (I think...).  The thought is to place a QPushButton immediately adjacent (on the right-side) of the QLineEdit to make it things look like regular QComboBox as much as possible. Then said button will .exec_() the QCalendarWidget (which is technically wrapped by a QDialog).
Let me know if this doesn't make sense, and I can provide further or clarified context.
You can try a QToolButton with no text and the arrowType property set to Qt.DownArrow.  eg: myqtoolbutton.setArrowType(Qt.DownArrow).
