Code: Select all
#include <QApplication>
#include <ccPointCloud.h>
#include <ccGLWidget.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
ccGLWindow *m_window = 0;
QWidget* m_widget = 0;
CreateGLWindow(m_window, m_widget);
m_widget->show();
ccPointCloud points;
return a.exec();
}
When I declared the ccPointCloud object as a pointer, errors would disappear.
like this
Code: Select all
#include <QApplication>
#include <ccPointCloud.h>
#include <ccGLWidget.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
ccGLWindow *m_window = 0;
QWidget* m_widget = 0;
CreateGLWindow(m_window, m_widget);
m_widget->show();
ccPointCloud *points = new ccPointCloud;
return a.exec();
}
Please help me~
Thank you.
