在QtQuick 2.0复杂的群体动画 [英] Complex group animation in QtQuick 2.0
本文介绍了在QtQuick 2.0复杂的群体动画的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试着去顶层续矩形动画的权利，下限它，将其移到右一点点，后面留在左侧刷卡。在同一时间，将向下尺度背面矩形也，它将规模大小设置为屏幕和将矩形平齐放置到屏幕的右侧。
会有人强麦给我如何我需要做它的一些指针？
请参考图片我想要实现
和我忘了说我如何将适用回落至动画呢？

Im trying to animate the top level "cont" rectangle to the right, downscale it, and move it over the right a little bit and the back to left on left swipe. At the same time it will down scale the back rectangle also, It will set the scale size to that of the screen and will place the rectangle flush to the right of the screen.
Would anyone be ale to give me some pointers on how I need to do it?
Check pictures for reference to what I'm trying to achieve
And I forgot to mention how would I apply easing to the animation as well?

I fixed some other issues that I was having with this app. So I restarted it and this is the new version with no errors and works very nicely.
