在Qt5的QtCreator套件设置中使用像％{buildDir}这样的变量 [英] Use of variables like %{buildDir} in QtCreator kit settings in Qt5

问题描述

在本文档中(在将自定义可执行文件指定为运行")，我注意到在工作目录"字段中提到了一个变量%{buildDir}.

In this documentation (under section "Specifying a Custom Executable to Run") I noticed that there is mention of what looks like a variable %{buildDir} in the field "Working directory".

我已经为寻找该功能的文档而苦苦挣扎了一段时间.我想首先了解在某处是否有此文档?.

I have struggled for a while now to find documentation for this feature. I would like to know first of all is there documentation for this somewhere?.

次要问题:

• 还有哪些其他变量?
• 可以在哪些字段中使用它们?
• 我可以访问在项目的.pro文件中创建的变量吗?
• 还有其他评估功能吗?还是这种机制仅限于变量?

• What other variables are available?
• In which fields can they be used?
• Can I access variables that I created in my project's .pro file?
• Are there any other eval features or is this mechanism limited to variables?

谢谢！

推荐答案

如注释中所述，有一个变量"按钮……据说可以在整个qt环境中使用.但是我只发现它在不太有用的不起眼的地方可用！

As mentioned in the comments there is a "variables" button... supposedly for use all over the qt environment. However I have only found it available in obscure places that are not very useful!

但是，您至少可以从这些位置获取var列表，​​并在实际需要它们的地方使用它们.要找到它，请导航至:

However, you can at least get the list of vars from these places and use them where you actually need them. To find this, navigate to:

• 工具(菜单)->选项->环境(标签)->外部工具
• 点击更新翻译..."
• 在工作目录.."内部单击，您应该在右侧看到一个带有颜色的"AB->"图标.
• 单击图标以显示您的变量列表.

您会注意到样式与%{BuildDir}略有不同，但我相信等同于%{CurrentProject:BuildPath}-您可以在第二个我右键单击的屏幕快照中看到它，它询问您要插入的内容(变量或变量的值).

You will notice that the style is a little different then %{BuildDir} but I believe the equivalent is %{CurrentProject:BuildPath} - You can see on the second screen shot I have right clicked and it asks you what you want to insert (the variable, or the value of the variable).

令人讨厌的是，我无法弄清楚如何复制/粘贴整个列表，因为它只是单行单击……也许更聪明的人可以弄清楚这一点，我们可以将该列表粘贴在一些Qt Wiki中:o

Annoyingly I could not figure out how to copy / paste the whole list as it is single line click only... maybe someone more clever can figure that out and we can stick that list in some Qt wiki :o

以下是屏幕截图...请注意，在屏幕截图1中，工作目录"文本编辑框右侧的小图标.

Here are the screen shots... Notice in screen shot 1 the little icon at the right side of "Working Directory" text-edit box.
