e4

问题 I am new to both Zest and Eclipse e4 development. My aim for the moment is to build a simple app and in one of its views to visualize a graph using Zest. So I am following this tutorial and I ended up with a simple working app consisting of one main window split in 3 parts. Now I want to display a graph in one of the parts. In order to do that I have downloaded the whole GEF framework into my Eclipse from here using the "Install New Software" feature of Eclipse. So far so good. Next I try to

问题 I'm testing an non-e4 RCP application using SWTBot and I need to change the size of my view. (Move the sash-bar) I unsuccessfully tried Resize my view using SWTBot (no such api) Resize my view using Eclipse 3 API (no supported) Resize my view using underlying e4 model (resizing not working) e4 model seams to be promising, but I'm missing something, so it doesn't work. I can Get MPart of my view: view = ePartService.findPart(ID) Get MTrimmedWindow: window = (view as EObject).eContainer as

问题 What I have now (notice there is no highlight): What I want (highlight the currently active part): Thanks a lot! 回答1: These colors are controlled by your CSS. Assuming you are using the usual e4 tab renderer the selected tab color can be set with: .MPartStack.active { swt-selected-tabs-background: #E5EDFC #99BAF3 100%; } By the 'usual tab renderer' I mean: .MPartStack { swt-tab-renderer: url('bundleclass://org.eclipse.e4.ui.workbench.renderers.swt/org.eclipse.e4.ui.workbench.renderers.swt

问题 A 3.* based RCP application will be restarted if IApplication.start returns IApplication.EXIT_RESTART. The class E4Application seems to always return EXIT_OK. org.eclipse.ui.IWorkbench also has a restart method, org.eclipse.e4.ui.workbench.IWorkbench does not. So how can I restart an e4 RCP application? 回答1: The current implementation in Eclipse 4.2 leads to a command with id org.eclipse.ui.file.restartWorkbench which ultimately leads to the handler class RestartWorkbenchHandler. This class

问题 Is there a way to replace the shell generated by Eclipse RCP for the MTrimmedWindow by a user defined window? Eclipse creates a shell with a particular style type, which can only be provided while creating. I want to remove maximize and resize from the shell element created for the MTrimmedWindow. If any one has a solution for the above problem please reply. 回答1: The style for the shell cannot be changed after creation, and the shell itself cannot be exchanged after it has been created by the

问题 I'm having a problem with command handlers in Eclipse Luna RCP. In my E4 application model, I defined some commands and related handlers that must be enabled only under certain circumstances. For this reason, in my handler POJOs, I implemented methods annotated with @CanExecute where I check the required conditions. I also defined menu and toolbar items associated with those commands. The problem is that my @CanExecute methods aren't properly invoked and, as a consequence, menu and toolbar

问题 I'm working on an E4 RCP application, and have a context menu which has menu items visible or not depending on the selection. The way I've found to do this is with core expressions defined in the plugin.xml like so: <extension point="org.eclipse.core.expressions.definitions"> <definition id="com.foo.bar.test.core.expression"> <with variable="org.eclipse.ui.selection"> <iterate ifEmpty="false"> <or> <instanceof value="com.foo.bar.Class1"> </instanceof> <instanceof value="com.foo.bar.Class2"> <

问题 The code from two years back had to be upgraded to E4, and now a bunch of stuff does not work anymore. One of these is the IEvaluationService if used like this: <handler class="org.acme.PrintHandler" commandId="org.eclipse.ui.file.print"> <activeWhen> <with variable="activePart"> <test property="org.acme.printable" /> </with> </activeWhen> </handler> IEvaluationService service = (IEvaluationService) PlatformUI.getWorkbench().getService(IEvaluationService.class); service.requestEvaluation("org

问题 I am developing e4 application. I want to inject EPartService outside the Part and Handler when i am injecting EPartService then i will get null pointer error public class DisplayRuntimePart { @Inject EPartService partService; private void displayPart(){ MPart part=partService.findPart("com.rcpe4.myproject.part.datapart"); mpart.setVisible(true); partService.showPart(mpart, PartState.CREATE); } } I am also read this question but till not solve my problem E4 EPartService findPart() throwing

问题 I'm trying to figure out how to make the Part's movable within a Part Stack in e4. Any ideas ? 回答1: To support drag and drop of parts you need the DndAddon and CleanupAddon specified in your Application.e4xmi. The Class URIs are: bundleclass://org.eclipse.e4.ui.workbench.addons.swt/org.eclipse.e4.ui.workbench.addons.dndaddon.DnDAddon bundleclass://org.eclipse.e4.ui.workbench.addons.swt/org.eclipse.e4.ui.workbench.addons.cleanupaddon.CleanupAddon This requires the org.eclipse.e4.ui.workbench
