class myDlg : public QDialog
{
    Q_OBJECT

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

private slots:
    void on_enterBtn_clicked();

private:
    Ui::myDlg *ui;
};

void BimDialog::on_Btn_clicked()
{
 QLineEdit* line = ui->lineEdit;
 line->setText("asadsshsasadhkfhdskh");
}
void BimDialog::on_Btn_clicked()
{
 QLineEdit* line = this->findChild<QLineEdit*>("lineEdit");
 line->setText("asadsshsasadhkfhdskh");
}

点击编辑信号槽

点击PushButton拖着不放指向窗体
