如果 \savebox 內沒有空間，則將右對齊文字移至下一行

tag-icon • tag-icon spacing horizontal-alignment boxes
如果 \savebox 內沒有空間，則將右對齊文字移至下一行

這是我之前問題的後續如果沒有空間，則將右對齊文字移至下一行。現在的區別是我需要將此格式化文字放在\savebox.在我的實際用例中，出於性能原因，我緩存需要跟隨現有文本（即在同一行上）的文本，並且此緩存的文本包含一些要與頁面邊緣右對齊的文本。

我嘗試使用所有四種解決方案如果沒有空間，則將右對齊文字移至下一行以及一個簡單的\hfill.這些似乎在外部使用時有效\savebox，但在內部時無效\savebox：

筆記：

  • 我可以不是使用\parbox{\linewidth}{}，因為我不知道該從哪裡\savebox開始。即同一行有文字前被\usebox應用。
  • 所需的版本將與文字XXX一樣在右側對齊ZZZ。
