Dynamic Scrollarea Content

[wysota]

This works for me:

#include <QtGui>
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  QScrollArea scroll;
  scroll.setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded); // it's default anyway
  QWidget *viewport = new QWidget;
  scroll.setWidget(viewport);
  scroll.setWidgetResizable(true);
  QVBoxLayout *l = new QVBoxLayout(viewport);
  for(int i=0;i<50;++i) {
    QPushButton *pb = new QPushButton(QString::number(i+1));
    l->addWidget(pb);
  }
  scroll.show();
  return app.exec();
}

#include <QtGui>

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QScrollArea scroll;
  scroll.setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded); // it's default anyway
  QWidget *viewport = new QWidget;
  scroll.setWidget(viewport);
  scroll.setWidgetResizable(true);
  QVBoxLayout *l = new QVBoxLayout(viewport);
  for(int i=0;i<50;++i) {
    QPushButton *pb = new QPushButton(QString::number(i+1));
    l->addWidget(pb);
  }
  scroll.show();
  return app.exec();
}
