如何自动检测RichEdit 2.0中的网址? [英] How to autodetect urls in RichEdit 2.0?

问题描述

当我们拥有RichEdit控件并向其发送WPARAM设置为TRUE的EM_AUTOURLDETECT消息时，它将很好地突出显示检测到的URL并发送EN_LINK通知. 但是它仅对输入到控件中的文本执行此操作.对于使用SetWindowText或EM_STREAMIN加载到控件中的文本，我还没有找到解决方法. 请帮忙！谢谢

When we have a RichEdit control and send it an EM_AUTOURLDETECT message with WPARAM set to TRUE, it nicely hightlights the detected URLs and sends the EN_LINK notifications. But it does this only for text that is entered into the control. I haven't found the way to do it for text that's loaded into the control with SetWindowText or EM_STREAMIN. Please help! Thanks

更新: 我已经从头开始创建了一个测试应用程序，并且在那里可以正常工作.我认为问题可能在于我已经超类了控件，即创建了一个新的窗口类，而只使用原始类的窗口过程.我将尝试将控件子类化..

Upd: I've created a test application from scratch and it works fine there. I think the problem might be that I have superclassed the control, that is, created a new window class and just use the window procedure of the original class. I'm gonna try subclassing the control instead..

推荐答案

我刚刚打开了一个基于WTL对话框的基本应用程序，其中包含riched20控件，并且可以正常工作:

I just knocked up a basic WTL dialog based app containing a riched20 control and the following works fine:

CRichEditCtrl richedit = GetDlgItem(IDC_RICHEDIT);
richedit.SetAutoURLDetect(TRUE);
richedit.SetWindowText(_T("http://www.stackoverflow.com"));

我有一些旧的MFC代码，尽管使用了ES_STREAM，但它们执行的功能类似，并且也可以正常工作.

I have some old MFC code that does something similar, albeit with ES_STREAM, and it works OK too.

FWIW WTL CRichEditCtrl包装器非常薄. SetAutoURLDetect只需调用SendMessage并将其传递给EM_AUTOURLDETECT.

FWIW the WTL CRichEditCtrl wrapper is pretty thin. SetAutoURLDetect simply calls SendMessage passing it EM_AUTOURLDETECT.

我正在将_RICHEDIT_VER设置为0x0200 FWIW.

I am compiling with _RICHEDIT_VER set to 0x0200 FWIW.
