to show a 3d plot at somewhere specified

[aopaw]

Hello,
Working on this began 2 day ago but failed to implement one.
I have duplicated a demo and re-configure it as a single project. For example, the simpleplot or dynamic plot can work well as a single project but shows memory violation error while I tried to display it inside a frame. Here is what I did
The object is declared as a member of TestGUI inheritted from QMainWindow
#include
#include "difplot.h" // given simply qwt3d plot things

namespace Ui {
class TestGui;
}

class TestGui : public QMainWindow
{
Q_OBJECT

public:
explicit TestGui(QWidget *parent = 0);
~TestGui();

private:
Ui::TestGui *ui;

Qwt3D::GridPlot * oPlot;
};
#endif // TESTGUI_H

What I can do to show it in TestGui.cpp if the main.cpp given as
#include "testgui.h"
#include

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
TestGui w;
w.show();

return a.exec();
}

hello,

oPlot = new Qwt3D::GridPlot()

is missing somewhere...
