// YYC MARK:
// 经过无数次的尝试我发现将int类型绑定到TextBox中所需要涉及的事情太多了
// 尤其是这种绑定到处存在于这个程序中,以至于每次都要重新写一遍。
// 也许后面我会做一个只能接受数字输入的文本框,但现在我累了。
//
// 具体来说事情是这样的。我一开始就是使用一个int类型的数据
// 然后按照CommunityToolkit.Mvvm的标准将其应用了Required和Range Attribute然后将其绑定到了TextBox的Text之上。
// 然而最终的效果很奇怪当我删除TextBox中的所有字符后绑定什么也没做后来我才知道要在Required里改一个选项
// 其次当我输入不被Range接受的数值时它仍会将其同步绑定到属性上。比如我输入0它仍会将其绑定到Fps上
// 进而导致Delta Time的转换显示抛出除以零的错误。这些都不是我想要的。
// 同时,这样做的话,我没有办法检测这些字段到底是不是合规的。
//
// 然后我就将int改写为了int?类型用null表示当前值不可接受非null表示绑定的值。
// 然后定义了一个转换器负责在int?和string之间进行转换并同时去除了所有的验证性Attribute
// 然而遗憾的是,这么做也不符合我的要求。当我尝试输入一个数值的时候,如果我输入了任何无效值,
// 那么转换器会将其转换为null值同时将该值赋给Fps而被赋值的Fps又反向传播把这个null传递给了转换器
// 转换器将其转换成为空白值,并显示在界面上。这么做的视觉效果就是一旦我输入无效值,整个文本框就会被清空,非常的反人类。
// 而且这一问题是不可调和的我不能在接收到null时选择不更新文本框的值因为有可能这个null是我手动放进去的而不是从转换器接受的。
//
// 所以最终我想通了我决定抛弃将int和TextBox.Text绑定在一起的想法。
// 就直接把string绑定到TextBox.Text上然后再辅以我自己定义的一套可复用验证逻辑。
