最大化MPart

时间：2016-11-16 09:54:27

标签： exception eclipse-rcp e4

我正在Eclipse应用程序中创建透视图。现在，为了处理我的观点，我创建了一些共享元素，以便在不同的视角之间进行分享。其中一个是MPartStack，其中包含一些动态MPart元素。

当我双击MPartStack中的MPart时，我得到了一些与MinMax插件相关的奇怪错误。但我希望在我的应用程序中具有最小最大行为。共享MPartStack中的所有MPart都存在此问题。普通MPartStack中的其他MPart我可以最小化和最大化而没有任何问题（只有共享的MPartStack不会被最小化）。

有人知道如何解决这个问题，以便我的用户可以正常地最小化和最大化堆栈吗？

我的完整堆栈跟踪：

我发现问题与Eclispe RCP中的已知问题相同。

他们建议使用MArea - ＆gt; MPartStack结构作为共享元素而不仅仅是MPartStack。直接使用Part Stack不是一个好主意，并且包含一些错误。
