C++ (Cpp) numberClicked示例

示例#1

文件： number_widget.cpp 项目： qbikez/booxsdk

void NumberWidget::onNumberButtonClicked(bool checked)
{
    // Downcast. Any other good idea?
    QAbstractButton * btn = static_cast<QAbstractButton *>(sender());
    bool ok = false;
    int number = btn->text().toInt(&ok);

    // Handle overflow.
    if (ok)
    {
        emit numberClicked( number );
    }
}
