Answer 1

#include <QtGui> class CustomTabStyle : public QProxyStyle{public: QSize sizeFromContents(ContentsType type, const QStyleOption *option, const QSize &size, const QWidget *widget) const { QSize s = QProxyStyle::sizeFromContents(type, option, size, widget); if (type == QStyle::CT_TabBarTab) { s.transpose(); s.rwidth()=70; s.rheight()=70; } return s; } void drawControl(ControlElement element, const QStyleOption *option, QPainter *painter, const QWidget *widget) const { if (element == CE_TabBarTabLabel) { if (const QStyleOptionTab *tab = qstyleoption_cast<const QStyleOptionTab *>(option)) { QStyleOptionTab opt(*tab); //opt.shape = QTabBar::RoundedNorth; opt.text = tr("Hello"); //QIcon icon(":/Resources/icon2.ico"); //opt.icon = icon; opt.palette.setCurrentColorGroup(QPalette::Disabled); opt.state |= QStyle::State_Sunken; QProxyStyle::drawControl(element, &opt, painter, widget); return; } } if (element == CE_TabBarTab) { painter->drawText(5,8,"1123"); //painter->setBackground(QBrush(Qt::red, Qt::SolidPattern)); } QProxyStyle::drawControl(element, option, painter, widget); }};
