加载workbench.xmi
我有一个简单的Eclipse 4 RCP应用程序。参数“-clearPersistedState”明确不用于使窗口的大小和位置在以后的启动时恢复。 问题是模型持久化为“.metadata / .plugins / org.eclipse.e4.workbench / workbench.xmi”包含整个应用程序状态。当我在更高版本中扩展应用程序的模型时，例如添加新的菜单条目和相关命令，如果找到持久性，则忽略这些添加。 使用“-deltaRestore”也不起作用。
如何确保应用程序的特定部分始终呈现在应用程序模型中的定义方式，而不是从“workbench.xmi”恢复其状态？ 是否可以只保留/恢复窗口的大小和位置？

1 个答案:
答案 0 :(得分：1)
如果您只想保存位置和尺寸，可以使用Colors"并将位置和尺寸保存在其他位置。
您可以从LifeCycle类中保存的数据设置主窗口的大小。 @ProcessAdditions方法似乎是最早可以做到的。类似的东西：
