If I create a QComboBox, use a stylesheet to increase or decrease the
font size, and put it within a QGridLayout, then the popup menu of the
combo box draws incorrectly.
With smaller fonts, it's too small vertically, and even if there are
only 2-3 items, the last item is cut off and a vertical scrollbar
appears. With larger fonts, the popup is tall enough but the items
overlap each other, leaving empty space at the bottom. Only 14px fonts
seem to work correctly.
I'm using Qt 4.7.3 and PyQt 4.7.2. The problem occurs on Windows and
Mac, but not Linux (though I may have different versions installed
there, I didn't have a chance to check).
Attached is a small program which demonstrates the problem.
I imagine this is really a Qt bug, but I don't do Qt C++ development so
I haven't had a chance to test it in that environment.
import sip
sip.setapi('QString', 2) # Map QStrings to Python strings
sip.setapi('QVariant', 2) # Auto-convert QVariants to/from Python types

css = """
QComboBox {
font: 10px;
}
"""
app = QApplication([])
w = QWidget()
g = QGridLayout(w)
c = QComboBox()
c.setStyleSheet(css)
for i in ['foo', 'bar', 'baz']:
c.addItem(i)
g.addWidget(c)
w.show()
app.exec_()
