Java 如何在EclipseRCP中使编辑器变脏
我已经尝试了很多方法让一个编辑器在RCP中变脏,但都没用。我正在为我的编辑器实现IEditorPart。当我编辑编辑器的内容时,它不会被标记为脏,保存按钮保持禁用状态。但是,当我单击“查看”时,“保存”将变为活动状态。我正在调用firePropertyChange(),但当我调试程序并进入firePropertyChange()时,侦听器列表发现为空。任何人都有解决方案,请分享。谢谢。打电话Java 如何在EclipseRCP中使编辑器变脏,java,eclipse,swt,rcp,Java,Eclipse,Swt,Rcp,我已经尝试了很多方法让一个编辑器在RCP中变脏,但都没用。我正在为我的编辑器实现IEditorPart。当我编辑编辑器的内容时,它不会被标记为脏,保存按钮保持禁用状态。但是,当我单击“查看”时,“保存”将变为活动状态。我正在调用firePropertyChange(),但当我调试程序并进入firePropertyChange()时,侦听器列表发现为空。任何人都有解决方案,请分享。谢谢。打电话 `public class ApplicationActionBarAdvisor extends Ac

将编辑器零件标记为脏零件
编辑器的
isDirty()
方法将在不同点被调用以检查脏状态。您是直接实现IEditorPart
还是扩展EditorPart
?@greg-449我正在扩展EditorPart@greg-449我正在调用firePropertyChange(),但当我调试程序并进入firePropertyChange()时侦听器列表为空。如果侦听器列表为空,则可能是未激发org.eclipse.ui.internal.BaseSaveAction
中的部分侦听器。你是如何打开编辑器的?@greg-449我正在通过发出命令打开编辑器。检查代码我做了,但它不工作。当我在调试时进入fireProperty change时,我发现侦听器列表为空,并从那里返回。不再调用侦听器。这是所有编辑器使用的标准机制。你最好给我们看看代码。
