再びなのですが、`UI`ファイルを作成したとき、（`QtDesigner`で、`GUI`を構築したとき）なのですが、いつも`ui->`で、橙色の波線が引かれ、  
**member Access into incomplete type UI::SortDialog**  
という警告文がエディタに表示されます。ヘッダファイルの設定が間違えているのでしょうか。それとも、コンパイラなどが違うからでしょうか。何かご存知の方はお願いいたします。

**sortdialog.cpp**

```

    #include "sortdialog.h"
    #include <QtGui>
    #include <QtWidgets>
    
    
    SortDialog::SortDialog(QWidget *parent) :
        QDialog(parent),
        ui(new Ui::SortDialog)
    {
        ui->setupUi(this);#here
        ui->secondaryGroupBox->hide();#here
        ui->tertiaryGroupBox->hide();#here
        layout()->setSizeConstraint(QLayout::SetFixedSize);
        setColumnRange('A','Z');
    
    }
    void SortDialog::setColumnRange(QChar first,QChar last)
    {
        ui->primaryColumnCombo->clear();#here
        ui->secondaryColumnCombo->clear();#here
        ui->tertiaryColumnCombo->clear();#here
    
        ui->secondaryColumnCombo->addItem(tr("None"));#here
        ui->tertiaryColumnCombo->addItem(tr("None"));#here
    
        ui->primaryColumnCombo->setMinimumSize(
                    ui->secondaryColumnCombo->sizeHint());#here
        QChar ch = first;
        while (ch <= last){
            ui->primaryColumnCombo->addItem(QString(ch));#here
            ui->secondaryColumnCombo->addItem(QString(ch));#here
            ui->tertiaryColumnCombo->addItem(QString(ch));#here
            ch = ch.unicode() + 1;
        }
    }
    SortDialog::~SortDialog()
    {
        delete ui;
    }
    
```

**sortdialog.h**

```

    #ifndef SORTDIALOG_H
    #define SORTDIALOG_H
    #include <QDialog>
    #include <QtUiTools/QUiLoader>
    namespace Ui {
    class SortDialog;
    }
    class SortDialog : public QDialog
    {
        Q_OBJECT
    public:
        SortDialog(QWidget *parent = nullptr);
        ~SortDialog();
        void setColumnRange(QChar first,QChar last);
    private:
        Ui::SortDialog *ui;
    };
    #endif // SORTDIALOG_H
    
```
