问题 I try to change the font size of package explorer in Eclipse from menu Window → Preferences → General → Appearance , and I fail to change the font size. How can I do that? I use Eclipse v4.2 (Juno) on Windows 7. 回答1: Eclipse is using native Windows widgets and their settings can only be changed from Display Properties / Settings / Advanced / General properties tab.

问题 I want to modify an existing e4 Application Model . In my modification I want to remove some elements inside the Application Model. E.g. Parts, Menu and so on. I am having the unique UI-Element-Id. How can I best remove some elements from the Application Model with this information.

问题 When running my RCP application in Eclipse it works correctly. If I export using the Eclipse Product export wizard and execute the application I get InjectionExceptions. I've found another question here that is the exact same problem. I've added org.apache.felix.scr to the product configuration but I'm still getting the same issue. I'm assuming another plug-in needs to be added but Add Recommended doesn't add any more. Start Levels Exception example !ENTRY org.eclipse.e4.ui.workbench 4 0 2019

问题 I am trying to extending "org.eclipse.ui.startup" extendion point. but it seems in eclipse e4 ,it does not even getting called. is this extension is broken in eclipse e4(Juno) 回答1: I had the same problem and couldn't find an answer, but in the process I discovered the LifeCycleHandler which is even better for my purpose.

问题 I've recently changed my Eclipse e4 applications project configuration from being based on plug-ins to features.

问题 I would like some parts to use a different renderer. In some cases I would like to remove the Detach option when right clicking and this is a solution according to a comment on my question here. I've been following this tutorial as to how this can be done. I've created two classes. UndetachableStackRenderer and UndetachableStackRendererFactory . If I add UndetachableStackRendererFactory to the plugin.xml it successfully removes the option to detach from ALL part stacks. <property name=

问题 I am using the latest Eclipse 4.7 Eclipse. I am trying to build a language sensitive editor for a pure e4 RCP application. I have modeled my editor after the example XML Text Editor template project (generated from File->New->Plug-in project). I have modified it and extended it to support my custom language (loosely based on specialized XML tags/elements/attributes).
