An implementation of QSyntaxHighlighter using GNU Source-highlight library (by relying on GNUSyntaxHighlighter provided by the common part of this library).
You can use such highlighter with a QTextEdit, and initialize the highlighter with the language definition file, e.g.,
void srchiliteqt::Qt3SyntaxHighlighter::formatString |
( |
int |
start, |
|
|
int |
count, |
|
|
const QFont & |
font, |
|
|
const QColor & |
color |
|
) |
| [inline] |
This function is applied to the syntax highlighter's current text block (i.e.
the text that is passed to the highlightParagraph() method).
The specified font and color are applied to the text from the start position for a length of count characters (if count is 0, nothing is done). The formatting properties set in format are merged at display time with the formatting information stored directly in the document, for example as previously set with QTextCursor's functions.
Note that this helper function will be called by the corresponding TextFormatter, from Source-highglight library code, and relies on the corresponding protected method of QSyntaxHighlighter: setFormat).
void srchiliteqt::GNUSyntaxHighlighter::highlightLine |
( |
const QString & |
line, |
|
|
HighlightStateData *& |
stateData |
|
) |
| [inherited] |
Highlights the passed line.
This method assumes that all the fields are already initialized (e.g., the FormatterManager).
The passed HighlightStateData is used to configure the SourceHighlighter with info like the current highlighting state and the state stack. If it is null, we simply ignore it.
This method can modify the bassed pointer and even make it NULL (after deleting it).
- Parameters:
-
line | |
stateData | the highlight state data to use |
- Returns:
- in case after highlighting the stack changed we return either the original stateData (after updating) or a new HighlightStateData (again with the updated information)
