QT界面开发-使用new QComboBox添加触发事件

 1     //创建QComboBox控件
 2             m_comboBox = new QComboBox(ww);
 3             m_comboBox->setObjectName(GBK::ToUnicode(sheet1Ini));
 4             m_comboBox->setGeometry(0, 0, 100, 20);
 5             m_comboBox->setFont(font);
 6             m_comboBox->move(150, ((i - 3) * 30) + 0);
 7             for (int j = 0; j < choiseData.size(); j++)
 8             {
 9                 m_comboBox->addItem(GBK::ToUnicode(choiseData[j].c_str()));
10             }
11             m_comboBox->setCurrentIndex(defaultValue);        
12             m_comboBox->show();
13             connect(m_comboBox, SIGNAL(currentIndexChanged(const QString)), this, SLOT(m_open(const QString)));
