问题 I am quite new to Eclipse 4, RCP and SWT and I am stuck on this issue : I want to access image resources from code with a relative filepath. Problem is that the default location ./ is set to my home directory /home/name/ (I'm using Ubuntu). I have found that by creating a new File and printing its CanonicalPath. I am used to having the default location set to the project directory, such as /home/name/workspace/project/ , which is, from what I've seen so far, the default behavior in Eclipse /

问题 I have an Eclipse plugin using RCP and Eclipse 4.5.2. This plugin is for developing a project of type "X". Right now, under File > New > Project... I have "X" within a category of "MyPlugin". I'd have to expand "MyPlugin" then double click on "X" to open the X version of the new project wizard. Is it possible to pre-select "X" when clicking on File > New > Project...?

问题 In one of our rcp application's window, I need to set label text dynamically after the creation of the window.

问题 This question stems from How to disable or enable a MMenu (not MMenuItem) in an Eclipse E4 application I have been attempting to grey-out/disable an entire Dynamic Menu Contribution in Eclipse 4 when a condition is met in the application.

问题 We have an application in which some views only work when attached to certain perspectives. We want to remove those views from the Window -> Show View dialog so that users cannot add them to perspectives where they don't work. Any ideas on how to do this either programmatically or declaratively? I have tried using <visibleWhen /> , but the views are still showing in the dialog: <view class="com.mycompany.ViewClass" id="com.mycompany.ViewId" name="View Name" restorable="true"> <visibleWhen>

问题 I would like to stop Parts from being detachable in Eclipse RCP 4. Currently if I right click on a Part I can select detach. From this I can then close the tab even if the Part isn't Closeable .
