你用的什么平台，Windows7下，Qt4.8.5、Qt5.5.1、Qt5.6.1、Qt5.7.0 下，如下代码没发现你描述的问题
- #include <QApplication>
#include <QDialog>
#include <QMainWindow>
class MainWindow : public QMainWindow
{
public:
MainWindow()
{
resize(800, 600);
setWindowTitle("MainWindow for show event test!");
}
protected:
void showEvent(QShowEvent *evt)
{
QDialog dlg;
dlg.resize(400, 300);
dlg.exec();
}
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow mw;
mw.show();
return a.exec();
}
