G_Settings应用更改 [英] G_Settings apply changes

问题描述

我正在做一些C编码，但无法永久存储g_settings！

Im doing some C coding but im unable to store g_settings permanently!

#include <stdlib.h>
#include <locale.h>


#include <gio/gio.h>
int main(int argc, char **argv)
{
  GSettings *settings;
  g_type_init();
  settings = g_settings_new ("org.nemo.desktop");
  printf("%s\n", g_settings_get_string(settings, "font"));
  g_settings_set (settings, "font", "s", "Arial");
  if (g_settings_get_has_unapplied (settings)) printf("X");
  printf("%s\n", g_settings_get_string(settings, "font"));
  return 0;
}

尝试使用Linux Mint 13 Cinnamon(路径等正确).

推荐答案

哦，起初我误读了您的代码...如果您想确保所做的更改已写入磁盘，我相信您应该致电g_settings_sync ().显然，如果您不使用mainloop进行运行(如您的示例案例)，则实际上需要这样做才能将所有内容存储在磁盘上.

Oh, I misread your code at first... I believe you should call g_settings_sync () if you want to ensure your changes are written to disk. Apparently if you run without a mainloop (like in your example case) this is really required to get things on disk at all.

因此，要清楚一点:具有glib mainloop的普通应用程序将不需要(也不应该真正使用)同步调用.

So, just to be clear: a normal application with a glib mainloop will not need (and shouldn't really use) a sync-call.
