[Solved]QTableWidget functions in a QTabWidget

[weblife]

How can I select a QTableWidget cell in a QTabWidget tab?

How I implement:

Wbook and Ssheet represent a workbook and spreadsheet. I implement them under ExcelMockWidget container class. I can’t figure out how to access my Ssheet cells once they have been added to a tab. I do understand Ssheet is cast into a QWidget data types once I insert into my Wbook data type, but would that matter?

Here is my repository for the "ExcelView Example":https://github.com/CCi-BClark/MockExcel .

ExcelMockWidget:
@
class ExcelMockWidget : public QWidget{
Q_OBJECT
public:
explicit ExcelMockWidget(QWidget *parent = 0);
~ExcelMockWidget();
void addCell(int row, int column, QVariant cell);
void addSheet(int index, QString title);
void setSheetProperties(int rows, int columns, QStringList headers);
signals:
void indexChanged(int);
public slots:
void emitIndexChange(int index);
void select(int row, int column);

private:
Wbook *book;
Ssheet *sheet;
};

ExcelMockWidget::ExcelMockWidget(QWidget *parent) : QWidget(parent) {
book = new Wbook;
QVBoxLayout *container;
container = new QVBoxLayout;
container->addWidget(book);
setLayout(container);
connect(book,SIGNAL(changedIndex(int)),this,SLOT(emitIndexChange(int)));
}

ExcelMockWidget::~ExcelMockWidget(){

}

void ExcelMockWidget::addCell(int row, int column, QVariant cell){
sheet->setCell(row,column,cell);
}

void ExcelMockWidget::addSheet(int index, QString title){
book->createTab(index, title, sheet);
}

void ExcelMockWidget::setSheetProperties(int rows, int columns, QStringList headers){
sheet = new Ssheet;
sheet->setSheetColumnSpan(columns);
sheet->setSheetRowSpan(rows);
sheet->setSheetHeaders(headers);
}

void ExcelMockWidget::emitIndexChange(int index){
emit indexChanged(index);
}

void ExcelMockWidget::select(int row, int column){
book->selectCell(row, column);
}

Wbook:
@
namespace Ui {
class Wbook;
}

class Wbook : public QWidget{
Q_OBJECT

public:
explicit Wbook(QWidget *parent = 0);
~Wbook();
void createTab(int index, QString title, Ssheet *worksheet);
void selectTab(int tab);
void selectCell(int row, int column);
signals:
void changedIndex(int);
public slots:
void emitIndexChange(int index);

protected:

Wbook::Wbook(QWidget *parent) : QWidget(parent), ui(new Ui::Wbook){
ui->setupUi(this);
connect(ui->tabWidget,SIGNAL(currentChanged(int)),this,SLOT(emitIndexChange(int)));
}

Wbook::~Wbook(){
delete ui;
}

void Wbook::createTab(int index, QString title, Ssheet *worksheet){
ui->tabWidget->insertTab(index, worksheet, title);
}

void Wbook::selectTab(int tab){
// 0 for no selection and 1 -> for created tabs.
ui->tabWidget->setCurrentIndex(tab);
}

void Wbook::selectCell(int row, int column){
ui->tabWidget->currentWidget()->childAt(row+1,column+1)->setFocus();
}

void Wbook::emitIndexChange(int index){
emit changedIndex(index);
}

Ssheet:

@
namespace Ui {
class Ssheet;
}

class Ssheet : public QWidget{
    Q_OBJECT
public:
    explicit Ssheet(QWidget *parent = 0);
    ~Ssheet();
    void setSheetTitle(QString title);
    void setSheetRowSpan(int n);
    void setSheetColumnSpan(int n);
    void setSheetHeaders(QStringList headers);
    void setCell(int row, int column, QVariant cell);

    void selectRow(int row);
    void selectCell(int row, int column);
private:
    Ui::Ssheet *ui;
};

Ssheet::Ssheet(QWidget *parent) : QWidget(parent), ui(new Ui::Ssheet){
    ui->setupUi(this);

    ui->table->verticalHeader()->setVisible(false);

    ui->table->setEditTriggers(QAbstractItemView::NoEditTriggers);
    ui->table->setSelectionBehavior(QAbstractItemView::SelectItems);
    ui->table->setSelectionMode(QAbstractItemView::SingleSelection);
    ui->table->setStyleSheet("QTableWidget {selection-background-color: black; selection-color: white}");

    ui->table->setShowGrid(false);
}

Ssheet::~Ssheet(){
    delete ui;
}

void Ssheet::setSheetTitle(QString title){
    ui->table->setObjectName(title);
}

void Ssheet::setSheetRowSpan(int n){
    ui->table->setRowCount(n);
}

void Ssheet::setSheetColumnSpan(int n){
    ui->table->setColumnCount(n);
}

void Ssheet::setSheetHeaders(QStringList headers){
    ui->table->setHorizontalHeaderLabels(headers);
}

void Ssheet::setCell(int row, int column, QVariant cell){
    QTableWidgetItem *input = new QTableWidgetItem;
    input->setData(0,cell);
    ui->table->setItem(row-1,column,input);
}

void Ssheet::selectCell(int row, int column){
    ui->table->setCurrentCell(row,column);
}

Thanks to Dmitry Markin on "SO":http://stackoverflow.com/a/20956440/3010222.

I had to make the following edits:

ExcelMockView:
@
void ExcelMockWidget::addSheet(int index, QString title){
Ssheet *newSheet(sheet);
book->createTab(index, title, newSheet);
}

void ExcelMockWidget::select(int row, int column){
sheet = static_cast<Ssheet*>(book->getCurrentWidget());
sheet->selectCell(row, column);
}
@

Wbook:
@
QWidget *getCurrentWidget(void);

QWidget* Wbook::getCurrentWidget(){
return ui->tabWidget->currentWidget();
}
