Qt QDialog界面delete问题，新人求解

Question

class test_menu : public QWidget
{
    Q_OBJECT
public:
    explicit test_menu(MainWindow *parent = 0);
    ~test_menu();

        QDialog *current_code_panel;
}

class test_code : public QDialog
{
    Q_OBJECT

public:
    explicit test_code(test_menu *parent=0);
    ~test_code();
}

void test_menu::createCodePanel()
{
    current_code_panel = new code_mov(this);
}

void test_menu::delCurrentPanel()
{
    /*方式一*/
    delete ((test_code*)current_code_panel);
    /*方式二*/
    delete current_code_panel;
    /*方式三(调用其他地方delete test_menu类的函数)*/
    emit CloseTestMenuPanel
}

上面三种delete test_menu的方式 都是正确的ma
