【问题描述】：
大家好 ！
我正在寻找解决方案从一个类的框架中制作一个网格.
以下代码不允许我使用画布在网格内放置 2 个对象（此处为描述和按钮）。
显然我应该将网格直接应用于框架，但如果我这样做; 该框不考虑尺寸和窗口的最小化。
目的是制作一个浮动工具栏（如史诗笔）！
因此，如果有人有解决方案来解决这个问题，那对你来说真的很好谢谢 =)！
这是带有画布的代码制作一个盒子我的物品：

这是直接应用于框架的网格代码在没有盒子尺寸的情况下运行；

对于这个故事，它是一个代码免费的开源工具放一个图片叠加应用对于那些不得不无图层再现 3D（如与超人类，或者想要再现人在 RPG 或任何其他功能中......
事实上，这个项目几乎完成了（比这更先进），但我想先清理它，我有点卡在这个基本问题上，所以谢谢帮助 ^^'
