刚学习Qt但是就遇到问题了！！！
#define QT3_SUPPORT
#include <QWidget>
#include <QApplication>
#include <QPushButton>
#include <Qt3Support/Q3ScrollView>
#include <QFont>
class MyMainWindow: public Q3ScrollView
{
public:
MyMainWindow();
private:
QPushButton *b1;
};
MyMainWindow::MyMainWindow()
{
this->setGeometry(100, 100, 200, 100);
b1 = new QPushButton("This button is not too\n big for the window", this);
b1->setGeometry(10, 10, 180, 80);
b1->setFont(QFont("Times", 18, QFont::Bold));
virtual void Q3ScrollView::addChild( b1 , 0, 0);
}
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyMainWindow w;
app.setMainWidget(&w);
w.show();
app.exec();
}
求各位能帮忙看下，我实在是没辙了。。。
