【摘要】 在linux系统下采用GTK+库进行应用于数控机床的图形界面编程时,一个具体的问题是:当菜单的层次结构比较复杂,单击了某一层次的某个菜单按钮后,如何找到对应所需要执行的功能函数?针对此问题,笔者提出了一个解决方法,此方法利用了数据结构中的哈希表来存储函数指针,通过哈希表的查找,可以成功地实现功能函数的调用。更多还原

【Abstract】 One problem in designing a GUI used in the numerical control machine tool with the GTK+ is how to find and execute the corresponding function when the layer’s structure is complex, to which a solution is brought forward: the Hash Table is used to store the pointers of functions, so that these functions can be found and executed through the search of the Hash Table.更多还原
