我有一个多页编辑器,其中每个页面都有复制粘贴删除操作和 f3 导航操作。我创建上下文并激活和停用操作
下面是 plugin.xml 的样子:
<extension
point="org.eclipse.ui.bindings">
<key
commandId="com.sap.adt.wda.controller.ui.navigate"
contextId="com.sap.adt.wda.controller.ui.contextTabScope"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
sequence="F3">
</key>
</extension>
<extension
point="org.eclipse.ui.contexts">
<context
description="%context_navigateToController_ymsg"
id="com.sap.adt.wda.controller.ui.contextTabScope"
name="%context_navigateToController_yins"
parentId="org.eclipse.ui.contexts.window">
</context>
</extension>
它是通过上下文的激活和停用来完成的。下面是代码片段。
private void activateHandlers() {
IContextService contextService = (IContextService) (PlatformUI.getWorkbench().getService(IContextService.class));
if (contextService != null) {
activation = contextService.activateContext(IControllerConstants.CONTEXT_TAB_ECLIPSE_CONTEXT_ID);
}
IEditorSite site = getEditor().getEditorSite();
IHandlerService service = (IHandlerService) site.getService(IHandlerService.class);
IHandlerActivation navigateHandlerActivation = service.activateHandler(NavigationHandler.COMMAND_ID, new NavigationHandler());
activatedHandlers = new ArrayList<IHandlerActivation>();
activatedHandlers.add(navigateHandlerActivation);
}
public void deactivateHandlers() {
IContextService contextService = (IContextService) (PlatformUI.getWorkbench().getService(IContextService.class));
contextService.deactivateContext(activation);
IHandlerService service = (IHandlerService) getEditor().getEditorSite().getService(IHandlerService.class);
if (activatedHandlers != null) {
service.deactivateHandlers(activatedHandlers);
activatedHandlers = null;
}
}
这两个方法分别从页面更改中调用,以在页面处于活动状态时激活上下文,在页面不处于活动状态时取消激活。
问题是它仍然与另一个打开的编辑器冲突,因为当我在编辑器之间切换时,甚至没有调用 pagechange !请告诉我实现这一点的最佳方法是什么。
