为什么我的程序信号连接到一个函数,一运行别的程序就退出

pvm6b

程序有两个按钮一个ok一个cencel但是运行buttok_do程序照样退出这是怎么回事
void buttcencel_do(GtkWidget* widget,gpointer data){
   gtk_main_quit();
}
void buttok_do(){
......
  没有退出程序
}
使用gtk_signel_connect连接

x11

建议好好想想怎么描述你的问题先

pvm6b

按照程序的执行,程序单击ok执行一个shell查找命令是否存在如果存在那么运行,退出当前窗口,如果没有找到命令那么显示错误提示窗口,单击取消直接退出,但是如果加上取消函数程序不能出显示任何错误提示都退出,去掉取消一切正常,不知为何
