本文主要是介绍解决RCP中CNF（navigator）配置后delete\copy\past快捷键失效，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
这两天在配置一个CNF导航视图时候发现快捷键delete、past、copy等都失效了，折腾良久，搞清楚了；
1.快捷键要想能在菜单右边显示出来：
deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);
2.要想生效必须绑定handler：
@Overridepublic void fillActionBars(final IActionBars actionBars) {if (textActionHandler == null) {textActionHandler = new TextActionHandler(actionBars); // hook// handlers}textActionHandler.setCopyAction(copyAction);textActionHandler.setPasteAction(pasteAction);textActionHandler.setDeleteAction(deleteAction);// renameAction.setTextActionHandler(textActionHandler);updateActionBars();textActionHandler.updateActionBars();}
public void updateActionBars() {actionBars.setGlobalActionHandler(ActionFactory.CUT.getId(),textCutAction);actionBars.setGlobalActionHandler(ActionFactory.COPY.getId(),textCopyAction);
actionBars.setGlobalActionHandler(ActionFactory.PASTE.getId(),textPasteAction);actionBars.setGlobalActionHandler(ActionFactory.SELECT_ALL.getId(),textSelectAllAction);actionBars.setGlobalActionHandler(ActionFactory.DELETE.getId(),textDeleteAction);}
setGlobalActionHandler把id和action绑定到一块；
这里你发现绑定的action并不是自己那个action，是texthandler中的action；
如果想强制生效可以直接把这个action换成我们那个action；
3.推荐的解决方法：
之所以不生效，是因为系统找不到action对应的commandid，我们可以绑定：
protected void makeActions() {clipboard = new Clipboard(shell.getDisplay());...deleteAction.setActionDefinitionId(IWorkbenchCommandConstants.EDIT_DELETE);initActionCommandMappingService();}/*** 快捷键绑定actionBars.setGlobalActionHandler();* 这里使用了textActionHandler.updateActionBars();所以绑定的是textActionHandler中text*Action，而不是这里的action；* 方法一：重新设置setGlobalActionHandler为这里的action；* 方法二：ActionCommandMappingService中添加这里的action映射WorkbenchCommandConstants.EDIT_**/private void initActionCommandMappingService() {final IActionCommandMappingService actionCommandMappingService = (IActionCommandMappingService) CommonUIPlugin.getDefault().getWorkbench().getActiveWorkbenchWindow().getService(IActionCommandMappingService.class);final String idDelete = actionCommandMappingService.getCommandId(ActionFactory.DELETE.getId());if (idDelete == null) {actionCommandMappingService.map(ActionFactory.DELETE.getId(), IWorkbenchCommandConstants.EDIT_DELETE);}final String idCopy = actionCommandMappingService.getCommandId(ActionFactory.COPY.getId());if (idCopy == null) {actionCommandMappingService.map(ActionFactory.COPY.getId(), IWorkbenchCommandConstants.EDIT_COPY);}final String idPast = actionCommandMappingService.getCommandId(ActionFactory.PASTE.getId());if (idPast == null) {actionCommandMappingService.map(ActionFactory.PASTE.getId(), IWorkbenchCommandConstants.EDIT_PASTE);}}
这样问题就解决了
