引き続きお願いします。
mainwindow.cppファイルで余計なメンバ関数は省いています。
下記のエラーが発生します。
1.lineEdit is a private member of 'GoToCellDialog'
2.variable has imcomplete type SpreadSheetCompare
3.no member named "name" in SortDialog
SortDialogとGoToCellDialogが関わっているようなのですが、どこがどうなっているのでしょうか。SortDialogについてはC++ GUI Programming with Qt 4 UIのエラー直前の質問でコードを載せてますので、申し訳ありませんがそちらをご覧ください。GoToCellDialogはここに載せます。（過去に掲載はしましたが不完全なので。）
mainwindow.cpp
#include "mainwindow.h"
#include "gotocelldialog.h"
#include "sortdialog.h"
#include "spreadsheet.h"
#include "finddialog.h"
#include "ui_gotocelldialog.h"
#include "ui_sortdialog.h"
#include <QtWidgets>
#include <QtGui>
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{ spreadsheet = new Spreadsheet;
setCentralWidget(spreadsheet);
createActions();
createMenus();
createContextMenu();
createToolBars();
createStatusBar();
readSettings();
findDialog = nullptr;
setWindowIcon(QIcon(":/images/icon.png"));
setCurrentFile("");
}
省略～
void MainWindow::goToCell()
{
GoToCellDialog *dialog = new GoToCellDialog(this);
if (dialog->exec()){
QString str = dialog->lineEdit->text().toUpper();#here lineEdit is a private member of 'GoToCellDialog'
spreadsheet->setCurrentCell(str.mid(1).toInt() -1,
str[0].unicode() - 'A');
}
}
void MainWindow::sort()
{
SortDialog *dialog = new SortDialog(this);
QTableWidgetSelectionRange range = spreadsheet->selectedRange();
dialog->setColumnRange('A' + range.leftColumn(),
'A' + range.rightColumn());
if (dialog.exec()){
SpreadSheetCompare compare;\\unknown type name "SpreadSheetCompare"
compare.keys[0] =
dialog->primaryColumnCombo->currentIndex() - 1;//here no member named "primaryColumnCombo" in SortDialog
compare.keys[1] =
dialog.secondaryColumnCombo->currentIndex() - 1;//here also
compare.ascending[0] =
(dialog.primaryOrderCombo->currentIndex() == 0);//here also
compare.ascending[1] =
(dialog.secondaryOrderCombo->currentIndex() == 0);//here also
compare.ascending[2] =
(dialog.tertiaryOrderCombo->currentIndex() == 0);//here also
spreadsheet->sort(compare);
}
}
