QFont font;

font.setPixelSize(m_FontSize);

m_LeftTopCornerLabel->setFont(font);

m_LeftBottomCornerLabel->setFont(font);

QFontMetrics fm(font);

int textHeight = fm.height();

int textWidth = fm.width(m_LeftTopCornerLabel->text());

m_LeftTopCornerLabel->setGeometry(2,0,textWidth,textHeight);

textWidth = fm.width(m_LeftBottomCornerLabel->text());

m_LeftBottomCornerLabel->setGeometry(2,m_Size.height()-textHeight,textWidth,textHeight);

QFont font1;

font1.setPixelSize(m_FontSize*m_FontSizeRatio);

m_CenterCommPriceLabel->setFont(font1);

QFontMetrics fm1(font1);

int commWidth = fm1.width(m_CenterCommPriceLabel->text());

int commHeight = fm1.height();

QFont font2;

font2.setPixelSize(m_FontSize/m_FontSizeRatio);

m_CenterBidAskPriceLabel->setFont(font2);

QFontMetrics fm2(font2);

int bidAskWidth = fm2.width(m_CenterBidAskPriceLabel->text());

int bidAskHeight = fm2.height();

textWidth = ( m_Size.width() - (commWidth + bidAskWidth) ) / 2;

m_CenterCommPriceLabel->setGeometry(textWidth,(m_Size.height()-commHeight)/2,commWidth,commHeight);

m_CenterBidAskPriceLabel->setGeometry(textWidth+commWidth,(m_Size.height()-bidAskHeight)/2,bidAskWidth,bidAskHeight);

注:字体的y值位置指字体的最下端的坐标，而非像其它窗体控件一样，y值指的top值。
