异步读取GUI消息队列 [英] Reading the GUI Message Queue asynchronously

问题描述

我正在寻找以任何方式异步读取GUI消息队列（使用回调）。

目前，我正在使用的软件目前使用  MsgWaitForMultipleObjectsEx
，带有标记  QS_ALLPOSTMESSAGE ，但这阻止了我不喜欢的线程（我想添加
async / await支持GUI框架）。

以下是我调查的选项：

  *存在" RegisterWaitForSingleObject"但不是"MsgRegisterWaitForSingleObject" （ 我需要的
） 

    *  有" SendMessageCallback"
但不是"GetMessageCallback" 

    *有" SetWindowsHookEx + WH_GETMESSAGE "
（但这似乎仅在你调用GetMessage时调用，这不是我想要的）

    *有像" MQReceiveMessage"这样的函数，但似乎无法从GUI消息队列中读取消息，或者至少I
没有找到任何信息。 / p>

有没有办法让其中一个选项有效，还是有其他我错过了？

如果不是，那不是一个好主意 实现此功能，因为越来越多的语言默认实现异步支持（async / await）？

解决方案

QS_ALLPOSTMESSAGE是唯一使用的标志吗？。 是否有理由不使用QS_ALLINPUT |等标志MWMO_INPUTAVAILABLE？

Hi,

I'm looking for any way to read the GUI message queue asynchronously (with a callback).

Currently, the software I'm working on currently uses MsgWaitForMultipleObjectsEx with the flag QS_ALLPOSTMESSAGE, but this blocks the thread which I don't like (I would like to add async/await support for a GUI framework) .

The following are the options I investigated:

  * There exists "RegisterWaitForSingleObject" but not "MsgRegisterWaitForSingleObject" (what I would need) 

   * There is "SendMessageCallback" but not "GetMessageCallback" 

   * There is "SetWindowsHookEx+WH_GETMESSAGE" (but this seems to be called only when you call GetMessage, which is not what I want)

    * There are the functions like "MQReceiveMessage", but it doesn't seem possible to read a message from the GUI message queue from it, or at least I didn't find any information.

Is there any way to make one of these options work, or is there another that I missed?

If not, wouldn't it be a good idea to implement this feature, as more and more languages implement asynchronous support by default (async/await)?

解决方案

Is QS_ALLPOSTMESSAGE the only flag being used?.  Is there a reason for not using flags such as QS_ALLINPUT | MWMO_INPUTAVAILABLE?
