如何从RCP中的IStatusLineManager获取消息？

Question

在某些情况下，我必须在单个状态栏上显示更多状态。当我尝试阅读消息并合并新消息（附加）时，无法使用IStatusLineManager获取现有消息。

Answer 1

IStatusLineManager statusline=w.getStatusLineManager();
statusline.update(true);
StatusLineContributionItem geographicalStatusLineItem = null;
            for (IContributionItem item : statusline.getItems()) {
                if (item instanceof StatusLineContributionItem) {
                    geographicalStatusLineItem = (StatusLineContributionItem) item;
                }
            }
         // create the status line
            if (geographicalStatusLineItem == null) {
                geographicalStatusLineItem = new StatusLineContributionItem("SelfTimeContributionItem");
                geographicalStatusLineItem.setText("Test");
                statusline.add(geographicalStatusLineItem);
            }

            geographicalStatusLineItem.setText("Test");
