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 I would like to start a new project which will make extensive use of plugins. I know that both Eclipse and Netbeans have their respective Rich Client Platforms, both with their respective strengths and weaknesses. I would like some comments on which the Stack Overflow community prefers. Also, and most importantly, how easy it is with the respective platforms to write plugins for already existing applications. For example, if I finish my application, and would like to enable 3rd parties to

问题 I am developing an eclipse plugin and trying to extend the source menu (mainMenubar/Source - visible when editing in the java-editor) in Eclipse 3.7. The documentation says to rely on the org.eclipse.ui.menus -extension point since the older extension points are deprecated. It is a complete secret to me where to obtain reliable locationURIs, but I finally managed to find some plausible URI with the Plugin Spy (following an advice here). So the following should be the extension snippet for the

问题 What are differences between Actions and Commands in the context of Eclipse RCP? I know that they both contribute to the menu entries, but which one is better? And why? Of all the online resources I read, I could not get a firm understanding of the differences between both. I have not actually tried to use them, but just wanted to understand them to start with from higher level point of view. Thanks 回答1: Did you read the eclipse wiki FAQ What is the difference between a command and an action?

问题 I have got ditched in a problem with Menu Contribution and PersistedState. I had no problem before removing the -clearPersistedState flag from the VM args. Now, the app has a weird behaviour, the menu contribution starts to pile up a menu entry every time the code is executed. Here it's the guilty snippet enclosed in a Processor: MDirectMenuItem menuItem = MMenuFactory.INSTANCE.createDirectMenuItem(); menuItem.setLabel("Another Exit"); menuItem.setContributionURI("bundleclass://" + "com

问题 I'm creating an application using eclipse RCP, I have many Part and I want to resize them. Some of these parts don't need many space. I've checked in Application.4xmi but I didn't found anything helpful. Any ideas? 回答1: You can set the size of a Trimmed Window in the Application.e4xmi by setting the Bounds width and height values. Usually you then use PartSashContainer to divide up the window. You specify a percentage used for each child in the Container Data for the child. 来源： https:/

问题 I have an Eclipse RCP plugin that requires a DLL. What is the recommended best practice to add the DLL reference to the MANIFEST? Where should the DLL be located, what is the recommended directory name? I have read conflicting practices. Some ask you to create a folder with the architecture and processor type, some ask to set some platform filters on the Manifest.... 回答1: The best way in an eclipse application is to use plug-in fragments. A standard eclipse project (with dlls) will have

问题 I have HandledMenuItem in my Application.e4xmi. But if I check this item, close my application and start it again, this item stay selected. I can suspect that this item should be tagged or something like this, but I can't find any information about tags for MenuItems. Thanks in advance. 回答1: The e4 RCP normally persists the state of the application model when the app terminates. If you don't want to restore the persisted state of the application use the -clearPersistedState flag. You can also
