  • 圖標分隔的斜間(\)與XML元素的終結斜間(/)正好相反。
  • 如果圖標欄後只有一個文字欄分隔「波浪-波浪」(~~),後面的文字會顯示在主文字欄而非時間距離欄。
  • 文字欄之間留空的話必須輸入空格,否則維基軟件會誤認為用戶簽名,且會被防濫用過濾器阻擋編輯。

圖標重疊與圖標鏈接[编辑]

圖標重疊
圖標鏈接
  • 重疊分隔「感嘆號-波浪」(!~)必須跟隨在下一層被重疊的圖標代碼之後。
  • 圖標重疊數基本是無限。
  • 使用圖標重疊的話,圖標連接分隔(!@)必須跟隨在最後(最頂)的圖標代碼之後。

  • 調整{{{text-width}}}參數直到路線圖的圖標之間沒有斷裂。
    • 默認單位為px,可以使用其他單位如em。
    • 注意要為不同瀏覽器調整最合適的最大寬度。
  • 摺疊行(摺疊區域的首行)的圖標欄數目必須等於整個路線圖的最大圖標欄數目。
    • 單雙數量的圖標行混用的場合下如例3.2,可以用半寬的空白圖標未定義路線圖圖標屬性"d"d)作為填塞。
  • 將「collapsed」改為「nil」可以令摺疊部分預設為展開。

  • 如欲隱藏取代行展開後的圖標,可以如例4.2以空白圖標leer)作為填塞。

  • 左文字欄以「感嘆號-空格-感嘆號」(! !)分隔圖標欄。
  • 「感嘆號-空格-感嘆號」的左邊沒有任何「波浪-波浪」(~~)文字分隔的話,其左邊第一組及唯一一組文字會顯示在左主文字欄。

  • 需要使用{{{text-width}}}參數的進階定義避免圖標行之間斷裂:
    • 只有一個數值時僅代表右主文字+右備註的寬度
    • 有3個數值時,以半型逗號分隔代表文字欄的寬度為:右時間距離,右主文字+右備註,右右備註
    • 6個數值:左左備註,左備註+左主文字,左時間距離,右時間距離,右主文字+右備註,右右備註
    • 數值不是1、3或6組會令參數失效。
  • 右右備註的文字長度少於一定量可以省略其寬度定義,如例6.1。
  • 如果整個路線圖都沒有使用某一組文字欄,該欄的寬度定義可以省略留空,如例6.2。
  • 摺疊行的空白圖標欄如果被擠壓,可以使用空白圖標leer)固定寬度。

Icon handling. Each icon is defined as in the following example:
icon ID!~overlap icon ID!@image link target
Values for an icon ID containing "*" are treated as text, with the letter(s) before "*" as width prefix(es).
No limit on overlapping icons or text; just separate them by "!~".
Parameters can be added after every object, separated to the left by "!_". This, if there is a link, must be after the link.
Parameters for individual objects in an overlapping stack can also be added, separated to the left by "__".
Unless a link is provided, each cell will have mouseover text indicating its contents.
