QComboBox::setMaxVisibleItems ( int maxItems )为什么不生效..

[kylin_try]

This property holds the maximum allowed size on screen of the combo box, measured in items.
By default, this property has a value of 10.

默认值都不生效

[system]

在ubuntu12.04，qt4.8.1下，我是这样解决的：
增加：comboxBox->setStyleSheet(“QComboBox { combobox-popup: 0 ;}”);
