Qt: some slots don't get executed in release mode

Question

I am doing some simple program in Qt (MSVC++2008) with few checkboxes and buttons. In debug mode, everything works fine, but I can't distribute such executable, because most people don't have Visual Studio installed. When I do compile it in release mode, only 2 pushbuttons work.

I have designed my window using Qt Creator's 'drawing tool' (Qt Designer, I guess). I do have such slots defined in my header file:

private slots:
    void on_goButton_clicked(); // Works fine

    void on_InputCheckBox_stateChanged(int arg1); // Don't work
    void on_outputFileCheckBox_stateChanged(int arg1); // Same as above

    void on_inputBrowseButton_clicked();  // Don't work, since theyre disabled
    void on_outputBrowseButton_clicked(); // Same as above

    void replyFinished(QNetworkReply *);

My implentation of those signals looks like this:

void MainWindow::on_InputCheckBox_stateChanged(int arg1)
{
    if (arg1 == Qt::Checked)
    {
        ui->inputEdit->setEnabled(true);
        ui->inputBrowseButton->setEnabled(true);
     }
    else
    {
        ui->inputEdit->setEnabled(false);
        ui->inputBrowseButton->setEnabled(false);
    }
}

void MainWindow::on_outputFileCheckBox_stateChanged(int arg1)
{
    if (arg1 == Qt::Checked)
    {
        ui->outputEdit->setEnabled(true);
        ui->outputBrowseButton->setEnabled(true);
    }
    else
    {
        ui->outputEdit->setEnabled(false);
        ui->outputBrowseButton->setEnabled(false);
    }
}

void MainWindow::on_inputBrowseButton_clicked()
{
    QString documents = DesktopServices::storageLocation(QDesktopServices::DocumentsLocation);
    QString filename = QFileDialog::getOpenFileName(
            this,
            tr("Select input file"),
            documents,
            tr("Text files (*.txt);;All files (*)"));
    if (filename.size() == 0)
        return;
    else
         ui->inputEdit->setText(filename);
}

void MainWindow::on_outputBrowseButton_clicked()
{
    QString documents = QDesktopServices::storageLocation(QDesktopServices::DocumentsLocation);
    QString filename = QFileDialog::getOpenFileName(
            this,
            tr("Select output file"),
            documents,
            tr("Text files (*.txt);;All files (*)"));
    if (filename.size() == 0)
        return;
    else
        ui->inputEdit->setText(filename);
}

Pardon for my English and thank you in advance.

Your code looks good.

Try running "make clean" or "qmake". Your "ui_" or "moc_" files might need updating.
