QML - 不支持命令性代码 [英] QML - Imperative code not supported
问题描述
有人可以评论 QML ，任何命令式 JavaScript 代码都不会执行，除非它是的额外组件。当我在我的QML中包含下面的代码时，我面临这样的问题：
Can someone comment on the fact that for QML, any imperative JavaScript code is not executed unless it is part of an extra component. I am facing such kind of problem when I include the following code to my QML:
function qmlSlot(text){
page.data=text
if(page.data==="received")
page.color="black";
}
由于Qt Designer被冻结并显示以下警告：
As the Qt Designer get frozen and shows the following warning:
Imperative code is not supported in the Qt Quick Designer
我阅读了构建 qmlpuppet 的安装可执行文件的 / bin 目录下的Qt建立它。如果qmlpuppet位于/ bin目录中，则 Qt Quick Designer 会检查当前项目的Qt。如果是，它需要由Qt版本提供的qmlpuppet，而不是由Qt Creator提供的。在我的情况下，我没有使用Qt静态二进制安装，而是从源代码构建Qt，因此已生成qmlpuppet 可执行文件，并已位于以下位置：
I read that building qmlpuppet installs an executable for rendering components in the /bin directory of the Qt building it. Qt Quick Designer checks for the Qt of the current project if a qmlpuppet is in the /bin directory. If yes it takes the qmlpuppet provided by the Qt version instead of the one provided by Qt Creator itself. In my case I haven't used the Qt static binary install, but instead built Qt from the source, thus qmlpuppet executable was generated and is already located at:
/usr/local/Qt-5.2.1/qtcreator/bin
-rwxr-xr-x 1 qml2puppet
-rwxr-xr-x 1 qmlpuppet
因此，可执行文件qmlpuppet被放置在预期被找到的地方，并且这个讨厌的消息继续。
So, the executable qmlpuppet is placed where is expected to be found and still this annoying message continues.
我立刻采取的解决方法是注释掉任何所谓的命令式代码，当我想使用Qt Designer编辑前端QML时。然后在取出这些意见后，再次激活命令性代码。但这是非常讨厌，虽然代码编译和工作，我预期它的行为。
The workaround I took at moment is to comment out any so called "Imperative code" for when I want to edit the front-end QML using Qt Designer. Then after take out those comments to have the "Imperative code" activated again. But this is very annoying, although the code compile and works as I expected it to behave.
那么，我应该担心这个警告吗？无论如何，有一些手段来摆脱这个问题，因为它冻结了Qt设计器？
So, should I get worried about this warning? Anyway, there is some mean to get rid of this problem, as it froze the Qt Designer?
推荐答案
QtCreator Bug：
This is currently a reported QtCreator Bug :
因此，不要担心警告，这将是修复
So don't be worried about the warning, it will be fix
