通过多线程 C++ GTKMM 运行 UI 每 5 秒获取一次传感器信息

如何解决通过多线程 C++ GTKMM 运行 UI 每 5 秒获取一次传感器信息

我一直在尝试在我的 UI(gtkmm3) 中显示传感器信息，使用 C++ 库“线程”，在调用函数 show_all_children(); 之前我会运行：

std::thread t1(get_sensor_info_thread);
t1.join();

调用这个函数（在构造函数外定义）：

void get_sensor_info_thread() {
    while (true) {
        system("sensors");
        sleep(5);
    }
}

我的程序执行但仅每 5 秒在终端中显示传感器信息并且不显示 UI，我尝试在显示所有子功能后启动线程，但发生同样的情况，感谢任何帮助:)>

我的构造函数和 get_sensor_info 代码：

#include "headers/MainWindow.h"
#include <ctime>
#include <iostream>
#include <string>
#include <thread>

void get_sensor_info_thread() {
    while (true) {
        system("sensors");
        sleep(5);
    }
}

MainWindow::MainWindow() :
mBox(Gtk::ORIENTATION_VERTICAL),headerBox(Gtk::ORIENTATION_HORIZONTAL),nBox1(Gtk::ORIENTATION_HORIZONTAL),lBox(Gtk::ORIENTATION_VERTICAL),rBox(Gtk::ORIENTATION_VERTICAL),sysBox(Gtk::ORIENTATION_VERTICAL),fanBox(Gtk::ORIENTATION_VERTICAL),cpuBox(Gtk::ORIENTATION_HORIZONTAL),gpuBox(Gtk::ORIENTATION_HORIZONTAL),moboBox(Gtk::ORIENTATION_HORIZONTAL) {

    set_title("NZXT Control UI");
    set_size_request(1000,600);
    set_resizable(false);
    add(mBox);

    mBox.pack_start(headerBox,Gtk::PACK_SHRINK);
    mBox.pack_start(mNotebook);

    prevButton.set_image_from_icon_name("go-prevIoUs",Gtk::ICON_SIZE_BUTTON);
    nextButton.set_image_from_icon_name("go-next",Gtk::ICON_SIZE_BUTTON);

    headerBox.pack_end(nextButton,Gtk::PACK_SHRINK);
    headerBox.pack_end(prevButton,Gtk::PACK_SHRINK);

    nextButton.signal_clicked().connect(sigc::mem_fun(*this,&MainWindow::on_next_page));
    prevButton.signal_clicked().connect(sigc::mem_fun(*this,&MainWindow::on_prev_page));

    mNotebook.popup_enable();
    mNotebook.set_scrollable();
    mNotebook.append_page(nBox1,"Stats",true);
    mNotebook.append_page(nBox2,"Fans",true);
    mNotebook.append_page(nBox3,"RGB",true);

    nBox1.pack_start(lBox);
    nBox1.pack_start(rBox);

    lTitle.set_text("System statistics");
    rTitle.set_text("Fan/AIO speed statistics");
    
    lBox.pack_stbar button or the CTRL+K keyboard shortcut. For more editing help,click the [?] toolbar icon.art(lTitle,false,0);
    rBox.pack_start(rTitle,0);

    sysFrame.set_label("System");
    fanFrame.set_label("Fans");
    lBox.add(sysFrame);
    rBox.add(fanFrame);
