如何以编程方式更改Eclipse Preferences [英] How to change Eclipse Preferences programmatically

问题描述

什么方法应该更改Eclipse首选项？

它们存储在< workspace> /。metadata / .plugin / org.eclipse.core.runtime / .settings

但是我希望找到Java API并发现任何偏好ID。

解决方案

如果您的插件激活器扩展了 AbstractUIPlugin 那么你可以调用

  IPreferenceStore prefStore = getPreferenceStore（）; 
  

在激活器中获取您的插件的首选商店。

您还可以使用

  IEclipsePreferences prefs = InstanceScope.INSTANCE.getNode node id）; 
  

以获得与首选项稍微不同的界面。

还有一个 org.eclipse.equinox.preferences.preferences 扩展点，可以让你定义一个'initializer'来设置首选项的默认值。 p>

What approach should be to change Eclipse Preferences?

They are stored in <workspace>/.metadata/.plugin/org.eclipse.core.runtime/.settings

But I hope to find Java API and a way to discover any preference ID.

解决方案

Somewhat confusingly there are several APIs a plugin can use for preferences.

If your plugin activator extends AbstractUIPlugin then you can call

IPreferenceStore prefStore = getPreferenceStore();

in the activator to get the preference store for your plugin.

You can also use

IEclipsePreferences prefs = InstanceScope.INSTANCE.getNode("node id");

to get a slightly different interface to the preferences.

There is also the org.eclipse.equinox.preferences.preferences extension point which lets you define an 'initializer' to set the default values for preferences.
