❝该示例演示如何显示系统中串行设备的信息。 ❞

此GUI示例在类QSerialPortInfo中提供有关小部件中的串行端口的信息。要获取有关可用端口的信息,请使用静态方法availablePorts()。
示例源码:
代码语言:javascript复制#include <QLabel>
#include <QScrollArea>
#include <QSerialPortInfo>
#include <QVBoxLayout>
#include <QWidget>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
auto layout = new QVBoxLayout;
const auto infos = QSerialPortInfo::availablePorts();
for (const QSerialPortInfo &info : infos) {
QString s = QObject::tr("Port: ") info.portName() "n"
QObject::tr("Location: ") info.systemLocation() "n"
QObject::tr("Description: ") info.description() "n"
QObject::tr("Manufacturer: ") info.manufacturer() "n"
QObject::tr("Serial number: ") info.serialNumber() "n"
QObject::tr("Vendor Identifier: ") (info.hasVendorIdentifier() ? QString::number(info.vendorIdentifier(), 16) : QString()) "n"
QObject::tr("Product Identifier: ") (info.hasProductIdentifier() ? QString::number(info.productIdentifier(), 16) : QString()) "n"
QObject::tr("Busy: ") (info.isBusy() ? QObject::tr("Yes") : QObject::tr("No")) "n";
auto label = new QLabel(s);
layout->addWidget(label);
}
auto workPage = new QWidget;
workPage->setLayout(layout);
QScrollArea area;
area.setWindowTitle(QObject::tr("Info about all available serial ports."));
area.setWidget(workPage);
area.show();
return a.exec();
}
