QTabWidget multiple tab show problem!

[bangqianchen]

I am add many tabs on a dialog, however, the tab arrow had overlap with tab text. the fellowing is part of my code.

//CTabPageDescInfomation is a subclass of QWidget.
	m_pTabWidget = new QTabWidget(this);
	m_pTabPage[Tab_Page_Basic] = new CTabPageDescInfomation(Tab_Page_Basic,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Basic],g_mapPages[Tab_Page_Basic]);
	m_pTabPage[Tab_Page_Botany] = new CTabPageDescInfomation(Tab_Page_Botany,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Botany],g_mapPages[Tab_Page_Botany]);
	m_pTabPage[Tab_Page_Agronomy] = new CTabPageDescInfomation(Tab_Page_Agronomy,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Agronomy],g_mapPages[Tab_Page_Agronomy]);
        //......
	connect(m_pTabWidget,SIGNAL(currentChanged(int)),this,SLOT(slot_tabSelChanged(int)));
	pH->addWidget(m_pTabWidget);

//CTabPageDescInfomation is a subclass of QWidget.
	m_pTabWidget = new QTabWidget(this);
	m_pTabPage[Tab_Page_Basic] = new CTabPageDescInfomation(Tab_Page_Basic,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Basic],g_mapPages[Tab_Page_Basic]);
	m_pTabPage[Tab_Page_Botany] = new CTabPageDescInfomation(Tab_Page_Botany,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Botany],g_mapPages[Tab_Page_Botany]);
	m_pTabPage[Tab_Page_Agronomy] = new CTabPageDescInfomation(Tab_Page_Agronomy,m_nDlgType,childFrm(),this);
	m_pTabWidget->addTab(m_pTabPage[Tab_Page_Agronomy],g_mapPages[Tab_Page_Agronomy]);
        //......
	connect(m_pTabWidget,SIGNAL(currentChanged(int)),this,SLOT(slot_tabSelChanged(int)));
	pH->addWidget(m_pTabWidget);
