Qt创建者高cpu在编辑器中的用法 [英] Qt creator high cpu usage in editor

问题描述

即使在简单的应用程序（简单的QWidgets应用程序从向导）qtcreator.exe峰值到50％（1核心）每隔一段时间编辑代码。似乎它解析整个项目，即使在几个新的字符后，输入，使其无响应，并且某些点不可用。

Even in simple applications (as simple as QWidgets app made from wizard) qtcreator.exe spikes to 50% (1 core) every other time when editing code. Seems like it parses the whole project even after several new characters where typed in, making it unresponsive and to some point unusable.

这变得更糟的项目大小，几个cpp / h模块有十几个类，它让人们紧张。

This gets worse with project size, so after adding several cpp/h modules with a dozen of classes it makes people nervous.

同样的项目在debian下的Qt完美无缺，我认为它连接到WinXP_x86。不能检查它是否在Win7下显示相同的行为。

The same project works flawlessly in Qt under debian, su I suppose it's connected to WinXP_x86. Can't check whether it exhibits the same behaviour under Win7.

这是通常的情况（我没有看到任何投诉在网络上，所以我想它不是），它可以完全固定，或者可以将代码解析切换到parse on save或类似的东西？

Is it the usual case (I don't see any complaints about it over the web so I suppose it's not), can it be fixed completely or can code parsing be switched to "parse on save" or something like it?

更新：Qt Creator在Win7上运行也不会显示这样的行为，所以它肯定是WinXP相关的问题

update: Qt Creator running on Win7 doesn't show such behaviour either, so it's definitely WinXP-related problem

推荐答案

code>选项 - > C ++ - >代码模型 - >忽略预编译的头文件选项（这是默认设置）似乎解决了问题 - 代码完成和解析现在是平滑的。我没有明确地在我的项目中使用PCH，所以不知道它是否影响其假设的目的，以提高性能。

Removing Options -> C++ -> Code model -> Ignore pre-compiled headers option (this is set by default) seems to fix the issue - code completion and parsing is smooth now. I don't use PCHs in my projects explicitly, so don't know whether it influences its supposed aim to improve performance.
