Why do it? Sometimes we need a non-windowed component (i.e. one that isn't derived fromTWinControl) to receive Windows messages. To receive messages the component needs a window handle, but a non-windowed component hasn't got one! This article is abo…

In some cases, you might need to pass a string from your intl messages.js file as a prop to a component. Instead of using react-intl components (which generate markup), we’ll use the injectIntl higher order component provided by react-intl. This will…

为什么要这样做? 有时候我们需要一个非窗口组件(比如一个非继承自TWinContrl的组件)可以接受Windows消息.要接受消息就需要一个窗口句柄,但是非窗口组件却没有句柄.这篇文章将讲述怎么让一个没有句柄的组件如何通过一个隐藏的窗口接受消息 这是怎么做到的? 例如我的剪贴板查看组件就是一个不可视的组件.这个窗体可以接收提供信息关于更改剪贴板的消息. Delphi库里面的AllocateHWnd函数可以帮助我们创建一个隐藏的窗口,同时与之相关的DeallocateHWnd函数可以释放当我们使用…

供RecyclerView采用.会员可以查看将替代ListView的RecyclerView 的使用(一),单单从代码结构来说RecyclerView确实比ListView优化了非常多.也简化了我们编写代码量.可是有一个问题会导致开发人员不会去用它,更比说替换ListView了.我不知道使用过RecyclerView的人有没有进一步查看.RecyclerView没有提供Item的点击事件.我们使用列表不只为了显示数据,同一时候也能够能会交互.所以RecyclerView这个问题导致基本没有人用它…
