deepin系统 qt编程如何获取显卡温度

您可以使用NVIDIA的NVML库来获取显卡温度，以下是获取显卡温度的代码示例：

#include <nvml.h>
#include <iostream>

int main()
{
    nvmlReturn_t result;
    nvmlDevice_t device;
    unsigned int temperature;

    // 初始化NVML库
    result = nvmlInit();
    if (result != NVML_SUCCESS) {
        std::cerr << "Failed to initialize NVML: " << nvmlErrorString(result) << std::endl;
        return -1;
    }

    // 获取第一个GPU设备
    result = nvmlDeviceGetHandleByIndex(0, &device);
    if (result != NVML_SUCCESS) {
        std::cerr << "Failed to get device handle: " << nvmlErrorString(result) << std::endl;
        nvmlShutdown();
        return -1;
    }

    // 获取温度
    result = nvmlDeviceGetTemperature(device, NVML_TEMPERATURE_GPU, &temperature);
    if (result != NVML_SUCCESS) {
        std::cerr << "Failed to get temperature: " << nvmlErrorString(result) << std::endl;
        nvmlShutdown();
        return -1;
    }

    std::cout << "GPU temperature: " << temperature << " degrees Celsius" << std::endl;

    // 关闭NVML库
    nvmlShutdown();

    return 0;
}

请注意，此示例仅适用于NVIDIA显卡。对于其他显卡品牌的温度获取，您需要查找相应的API。
