Flex 拖动并调整大小
我需要通过鼠标在画布上拖动来绘制线条、圆形和矩形,然后需要移动绘制的形状并调整其大小。 我如何在 Flex 中执行此操作,因为我是这个平台的新手。 请建议我该方法或参考任何带有源代码的示例,以便我理解。 请帮忙。 提前致谢。

Flex 中没有这样的原生功能。 但是,有几个选项,商业的和非商业的:

如果您愿意,您可以手工完成,这并不难。 我建议您使用 Degrafa (http://degrafa.org/) 进行实际绘图,因为它更容易比原生绘图 API 更重要,而且它是开源的。
There is no such native feature in Flex. But, there are a couple of options, commercial and not:

You can do it by hand, if you wish, it's not very hard. I advice you to use Degrafa (http://degrafa.org/) for the actual drawing since it is way easier than native drawing API and it is opensource.
