如何在 QT 中使用 c++ 获取系统配置

Question

我想要系统配置，如 cpu 或显卡型号。

Answer 1

QSysInfo was meant for this purpose.

For example, you can get the CPU architecture using currentCpuArchitecture .

Qt uses OpenGL for the rendering, so there is no need for specific API in there as you can use the standard OpenGL API for that:

glGetString(GL_VENDOR);
glGetString(GL_RENDERER);

For network information, you can use QNetworkInformation .

For store information, you can use QStorageInfo .

For serial port information (I actually developed this one), you can use QSerialPortInfo .

For printer information, you can use QPrinterInfo .

For bluetooth information, you can use QBluetoothDeviceInfo .

For can bus device information, you can use QCanBusDeviceInfo .

A good hint is to search for "info" classes in all Qt classes .

Qt has consistently named the classes so during its development.
