Problem with Parent QWidget and Buttons not working

[wysota]

This works fine (maybe you forgot about Q_OBJECT?)

#include <QApplication>
#include <QPushButton>
#include <QLayout>
 
class MyPushButton : public QPushButton {
Q_OBJECT
public:
  MyPushButton(QWidget *parent=0) : QPushButton(parent){}
};
 
#include "main.moc"
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  QWidget w;
  QVBoxLayout *l = new QVBoxLayout(&w);
  l->addWidget(new MyPushButton);
  l->addWidget(new QPushButton);
  app.setStyleSheet(".MyPushButton{ border: 2px solid black; }");
  w.show();
  return app.exec();
}

#include <QApplication>
#include <QPushButton>
#include <QLayout>

class MyPushButton : public QPushButton {
Q_OBJECT
public:
  MyPushButton(QWidget *parent=0) : QPushButton(parent){}
};

#include "main.moc"

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QWidget w;
  QVBoxLayout *l = new QVBoxLayout(&w);
  l->addWidget(new MyPushButton);
  l->addWidget(new QPushButton);
  app.setStyleSheet(".MyPushButton{ border: 2px solid black; }");
  w.show();
  return app.exec();
}
