[SOLVED] QSignalMapper and QStandardItemModel

**guidupas** · 17th April 2014, 20:23

Hello everyone!

I need to link a button click signal to add a row in my QStandardItemModel and I am trying to do this way, but It's not going OK.

Qt Code:

Switch view

void MainWindow::on_pushButtonNovoInvestimento_clicked()
{
    QPushButton *pushButtonAdicionarLancamentoInvestimento = new QPushButton;
    pushButtonAdicionarLancamentoInvestimento->setText("Adicionar lanÃ§amento");        
 
    QTableView *tableViewLancamentosInvestimento = new QTableView;
    QStandardItemModel *modeloLancamentosInvestimento = new QStandardItemModel(0, 2, this);
    modeloLancamentosInvestimento->setHeaderData(0, Qt::Horizontal, "Valor");
    modeloLancamentosInvestimento->setHeaderData(1,Qt::Horizontal, "AÃ§Ãµes");
    tableViewLancamentosInvestimento->setModel(modeloLancamentosInvestimento);
 
    QSignalMapper *mapper = new QSignalMapper;
    connect(pushButtonAdicionarLancamentoInvestimento, SIGNAL(clicked()), mapper, SLOT(map()));
    mapper->setMapping(pushButtonAdicionarLancamentoInvestimento, modeloLancamentosInvestimento);
    connect(mapper, SIGNAL(mapped(QObject*)), this, SLOT(on_pushButtonAdicionarLancamentoInvestimento_clicked(QObject*)));
}
 
void MainWindow::on_pushButtonAdicionarLancamentoInvestimento_clicked(QObject *modeloLancamentosInvestimento)
{
    QStandardItemModel *modelo = modeloLancamentosInvestimento;
}

void MainWindow::on_pushButtonNovoInvestimento_clicked()
{
    QPushButton *pushButtonAdicionarLancamentoInvestimento = new QPushButton;
    pushButtonAdicionarLancamentoInvestimento->setText("Adicionar lanÃ§amento");        

    QTableView *tableViewLancamentosInvestimento = new QTableView;
    QStandardItemModel *modeloLancamentosInvestimento = new QStandardItemModel(0, 2, this);
    modeloLancamentosInvestimento->setHeaderData(0, Qt::Horizontal, "Valor");
    modeloLancamentosInvestimento->setHeaderData(1,Qt::Horizontal, "AÃ§Ãµes");
    tableViewLancamentosInvestimento->setModel(modeloLancamentosInvestimento);

    QSignalMapper *mapper = new QSignalMapper;
    connect(pushButtonAdicionarLancamentoInvestimento, SIGNAL(clicked()), mapper, SLOT(map()));
    mapper->setMapping(pushButtonAdicionarLancamentoInvestimento, modeloLancamentosInvestimento);
    connect(mapper, SIGNAL(mapped(QObject*)), this, SLOT(on_pushButtonAdicionarLancamentoInvestimento_clicked(QObject*)));
}

void MainWindow::on_pushButtonAdicionarLancamentoInvestimento_clicked(QObject *modeloLancamentosInvestimento)
{
    QStandardItemModel *modelo = modeloLancamentosInvestimento;
}

To copy to clipboard, switch view to plain text mode

How can I do that?

Thanks a lot
