java - Eclipse RCP 3.X 到 4——经典 CSS

Question

我有一个非常旧的 3.X RCP Eclipse 元素，我正在尝试升级到 4，但我想修复该元素的初始问题是使样式与 RCP 经典 CSS 相匹配。我试过以下:http://www.eclipse.org/forums/index.php/m/1034649/?srch=3.x+rcp+theme+css#msg_1034649创建相同的样式但无济于事，所以我只能假设我做错了什么(惊喜)。我对 RCP 很陌生，所以请原谅这个解释。该链接谈到了我在 project.product 文件中看到的扩展点添加，但不确定如何将其添加到那里，所以我将其添加到 plugin.xml 中。总的来说，我希望有更好的理解，这样我至少可以在解决其他一些问题之前完成样式设置。

添加 plugin.xml:

Answer 1

所以我很愚蠢，在 .product(启动选项卡)中没有 -clearPersistedState，因此，css 没有更新。你知道的越多。
