QT中可以用以下方式改变QCombobBox风格，有没有全部控件的参数. [复制链接]

 QString l_sStyleSheet = "QComboBox::drop-down {\
       border-image: url(Resources/southResizeCursor.png) 5;\
       border-width: 5;\
       }\
       QComboBox{\
       border-image: url(Resources/timelinePillGreen.png) 5;\
       border-width: 5;\
       }\
       ";
 ui.comboBox->setStyleSheet(l_sStyleSheet);
 ui.comboBox->addItem("test1");
 ui.comboBox->addItem("test2");
 ui.comboBox->addItem("test3");

比如：我还想修改其它控件怎么办？那些参数是什么？
"QComboBox::drop-down {\
xxxxxxxxxxxx::xxxxxxxxxxxx
