qemu 开发gtk界面 demo

以下是一个简单的 QEMU GTK GUI 应用程序的示例代码：

#include <gtk/gtk.h>
#include <glib.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>

#include "qemu/qemu.h"
#include "qemu/qemu-option.h"

GtkWidget *window;
GtkWidget *start_button;
GtkWidget *stop_button;
GtkWidget *console_text;

QEMUOption option;

static void on_start_button_clicked(GtkWidget *widget, gpointer data)
{
    char *cmd = g_strdup_printf("qemu-system-%s -hda %s", option.arch, option.disk_image);
    FILE *fp = popen(cmd, "r");
    if (fp == NULL) {
        perror("popen failed");
        return;
    }
    char buf[1024];
    while (fgets(buf, sizeof(buf), fp) != NULL) {
        gtk_text_buffer_insert_at_cursor(gtk_text_view_get_buffer(GTK_TEXT_VIEW(console_text)), buf, strlen(buf));
    }
    pclose(fp);
}

static void on_stop_button_clicked(GtkWidget *widget, gpointer data)
{
    // TODO: Stop the QEMU process
}

static void on_window_destroy(GtkWidget *widget, gpointer data)
{
    gtk_main_quit();
}

int main(int argc, char *argv[])
{
    gtk_init(&argc, &argv);

    // Initialize the QEMU option
    option.arch = "x86_64";
    option.disk_image = "/path/to/disk_image.img";

    // Create the main window
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(window), "QEMU GUI");
    gtk_window_set_default_size(GTK_WINDOW(window), 640, 480);
    g_signal_connect(window, "destroy", G_CALLBACK(on_window_destroy), NULL);

    // Create the start button
    start_button = gtk_button_new_with_label("Start QEMU");
    g_signal_connect(start_button, "clicked", G_CALLBACK(on_start_button_clicked), NULL);

    // Create the stop button
    stop_button = gtk_button_new_with_label("Stop QEMU");
    g_signal_connect(stop_button, "clicked", G_CALLBACK(on_stop_button_clicked), NULL);

    // Create the console text view
    console_text = gtk_text_view_new();
    gtk_text_view_set_editable(GTK_TEXT_VIEW(console_text), FALSE);
    gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(console_text), GTK_WRAP_WORD_CHAR);

    // Create a vertical box layout
    GtkWidget *vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 5);
    gtk_container_add(GTK_CONTAINER(window), vbox);

    // Add the start button to the layout
    gtk_box_pack_start(GTK_BOX(vbox), start_button, FALSE, FALSE, 0);

    // Add the stop button to the layout
    gtk_box_pack_start(GTK_BOX(vbox), stop_button, FALSE, FALSE, 0);

    // Add the console text view to the layout
    GtkWidget *scroll = gtk_scrolled_window_new(NULL, NULL);
    gtk_container_add(GTK_CONTAINER(scroll), console_text);
    gtk_box_pack_start(GTK_BOX(vbox), scroll, TRUE, TRUE, 0);

    // Show all widgets
    gtk_widget_show_all(window);

    // Enter the GTK main loop
    gtk_main();

    return 0;
}

该示例代码仅包含了启动和停止 QEMU 的基本逻辑，并没有对 QEMU 进行更高级的配置和控制。你可以根据需要修改代码，并添加其他功能来完善你的 QEMU GTK GUI 应用程序。
