class form:public QMainWindow

Q_OBJECT
public:

Ui::MainWindow ui;
public slots:
void insertItem();
};
form::form()
{
window = new QMainWindow;
ui.setupUi(window);
connect(ui.pushButton_insert, SIGNAL(clicked()), this, SLOT(insertItem()));
}
void form::insertItem()
{
QString strInsert = ui.lineEdit->text();
if(strInsert.isEmpty())
{
QMessageBox::warning(this, tr("ALERT"), tr("enter words in line"), tr("ok"));
ui.lineEdit->setFocus();
}
else
{
ui.listWidget->addItem(ui.lineEdit->text());
ui.lineEdit->clear();
}
}
这样写可以吗?
但在编译时出现如下错误
请高人帮忙看看并指正:
