清空所有快取的語法高亮資料。

|
|
|
|
Returns the syntax highlighting data for the line at index ``line``. If the line is not cached, calls :ref:`_get_line_syntax_highlighting()<class_SyntaxHighlighter_private_method__get_line_syntax_highlighting>` first to calculate the data.
|
|
|
|
Each entry is a column number containing a nested :ref:`Dictionary<class_Dictionary>`. The column number denotes the start of a region, the region will end if another region is found, or at the end of the line. The nested :ref:`Dictionary<class_Dictionary>` contains the data for that region. Currently only the key ``"color"`` is supported.
|
|
|
|
\ **Example:** Possible return value. This means columns ``0`` to ``4`` should be red, and columns ``5`` to the end of the line should be green:
|
|
|
|
::
|
|
|
|
{
|
|
0: {
|
|
"color": Color(1, 0, 0)
|
|
},
|
|
5: {
|
|
"color": Color(0, 1, 0)
|
|
}
|

}

清除然後更新 **SyntaxHighlighter** 快取。為一個回呼函式覆蓋 :ref:`_update_cache()<class_SyntaxHighlighter_private_method__update_cache>`\ 。
|
|
|
|
\ **注意：**\ 當關聯的 :ref:`TextEdit<class_TextEdit>` 節點更新它自己的快取時，該函式會被自動呼叫。
