c - 如何为 Glade 的 GTK 按钮分配命令？

Question

我用 Glade(a.glade 文件)设计了界面和按钮。然后我编写一个C语言文件(e.c文件)将命令分配给按钮，虽然它没有报告错误，但按钮不执行命令，我的“e.c”文件中是否缺少某些内容？

在 a.glade 文件中:

      <object class="GtkButton" id="buttonn">
        <property name="label" translatable="yes">OK</property>
        <property name="related_action"/>
        <property name="width_request">126</property>
        <property name="height_request">51</property>
        <property name="visible">True</property>
        <property name="can_focus">True</property>
        <property name="receives_default">True</property>
        <property name="halign">center</property>
        <property name="valign">center</property>
        <property name="margin_left">15</property>
        <property name="margin_right">15</property>
        <property name="margin_top">15</property>
        <property name="margin_bottom">15</property>
        <signal name="clicked" handler="on_buttonn_clicked" swapped="no"/>
      </object>

在e.c文件中:

int main(int argc, char *argv[])
{
  GtkBuilder *builder; 
  GtkWidget *window;
  gtk_init(&argc, &argv);
  builder = gtk_builder_new();
  gtk_builder_add_from_file (builder, "a.glade", NULL);
  window = GTK_WIDGET(gtk_builder_get_object(builder, "windoww"));
  gtk_builder_connect_signals(builder, NULL);
  g_object_unref(builder);
  gtk_widget_show(window);                
  gtk_main();
  return 0;
}

和:

// called when button is clicked
void on_buttonn_clicked()
{
  char command[50];
  strcpy( command, "touch a.txt" );
  system(command);
}

@DavidCollins 嗨!感谢您的帮助。我尝试在我的编译代码中添加一个标志，它起作用了。我添加了 -rdynamic 标志，完全编译的代码是:

gcc -rdynamic -no-pie -Wall -g -o e e.c `pkg-config --cflags --libs gtk+-3.0`

感谢您的帮助。
