Flex 3 加载背景颜色
在加载 Flex 3 构建的应用程序期间，它始终显示这种蓝灰色背景颜色。我尝试了一些技巧，构建预加载器等，所有这些都有效，但即使在预加载器启动之前，也会显示蓝灰色。我尝试了很多方法来更改它，例如编辑编译器选项、将背景图像设置为空字符串等，但没有任何效果。
During loading of a Flex 3 built application, it always shows this blue-grayish background color. I've tried a handful of tips, building preloaders etc, and all that works, but even before the preloaders kick in, that blue-grayish color is displayed. I've tried lots of ways to change it, like editing compiler options, setting background image to an empty string etc, but nothing works.

我遇到了同样的问题，并花了一个小时寻找解决方案。据我所知，蓝灰色是直接从index.template.hmtl生成的HTML文件设置的。该文件中的
下有一个用于设置背景颜色的绑定。我假设 bgcolor 应该从您在应用程序中设置的 backgroundColor 中提取。您也可以尝试在该参数中对您的值进行硬编码。I had this same issue and spent a good hour looking for a solution. To the best of my understanding, the blueish-grey color is directly set from the HTML file generated from index.template.hmtl. There is a binding in that file under
<param name="bgcolor" value="{bgcolor}" />that sets the background color. I'm assuming that bgcolor should be pulled from the backgroundColor you set in your Application. And you could also just try hard coding your value in that param also.要在加载时超越默认的“蓝色”背景，例如...白色，请将其添加到编译器参数中：-default-background-color #ffffff。
To get past the default 'bluish' background on loading to say...white, add this to the compiler arguments: -default-background-color #ffffff.
