前面几篇文章中的控件基本上难度系数接近0,甚至有凑控件数量的嫌疑,这次必须来一个强悍的控件,本控件难度系数在所有控件中排前五,代码量也不少,头文件都550行,实现文件1600行,为什么这么多呢,其实本控件是由好多个子控件组成的,字母高亮背景类、中间字母分隔类、右侧字母导航类、通讯录按钮类、自定义滚动条类,我在写比较复杂的控件的时候,一般都会逐个功能拆分,然后思考是否该功能可以做成独立的类,这样管理起来比较方便,也方便查看代码。
最开始拿到这个控件需求的时候,也觉得不会简单,要求用纯QWidget实现,qml实现滑动等各种效果很方便,天生的优势,而QWidget就需要自己来实现了,需求主要是要求五点,能够批量和单个添加联系人信息(头像+姓名+标识)、能够滑动列表悬浮滚动条、能够自动按照字母分类、提供字母导航栏直接快速定位、单击联系人发出对应联系人的详细信息。
