在使用QComboBox时，出现这个错误Attempt to bind non-signal QComboBox::currentIndexChanged(int)。请问为什么会报这个错呢？代码如下：
m_comboBoxPro = new QComboBox(this);
m_comboBoxPro->setStyleSheet("QComboBox{font-family:'SimHei';font-size:9; border:1px solid lightgray;}"
"QComboBox QAbstractItemView::item {min-height: 16px;}"
"QComboBox::drop-down{border-left-width: 1px;border-left-color: lightgray;border-left-style: solid; border-top-right-radius: 3px;border-bottom-right-radius: 3px;subcontrol-origin: padding;subcontrol-position: top right; width:20px;}"
"QComboBox::down-arrow{image:url(:/res/pwd/arrowDown01.png)}"
"QComboBox::down-arrow:hover{image:url(:/res/pwd/arrowDown01.png)}"
"QComboBox::down-arrow:pressed{image:url(:/res/pwd/arrowDown01.png)}");
m_comboBoxPro->addItem(QString("123"));
m_comboBoxPro->addItem(QString("456")) ..
