#include<QListView>

QComboBox* m_pCboText;

pCboCar=newQComboBox(this);

    pCboText->setFixedSize(200,25);

    pCboText->addItem(QString::fromLocal8Bit("一一一一一一一一一一一一一"));

    pCboText->addItem(QString::fromLocal8Bit("二二二二二二二二二二二二二二"));

    pCboText->addItem(QString::fromLocal8Bit("三三三三三三三三三三"));

    pCboText->addItem(QString::fromLocal8Bit("四四四"));
