Makes sense. I will try to get the higher level lexer class for Matlab/Octave
done and contribute it back to the project. That issue aside, I am still
having problems getting QScintilla to highlight even using the low-level
support. I added the following to the constructor of the MainWindow class for
the example-Qt4 project after the textEdit object has been created.
textEdit->SendScintilla (QsciScintillaBase::SCI_SETLEXERLANGUAGE, "octave");
// Also tried this, but it didn't work either
//textEdit->SendScintilla (QsciScintillaBase::SCI_SETLEXER,
QsciScintillaBase::SCLEX_MATLAB);
textEdit->SendScintilla (QsciScintillaBase::SCI_SETKEYWORDS, "for if end");
It did not syntax highlight an m-file when I opened it. So, I tried putting it
in the loadFile() method of the MainWindow in the example, think that maybe you
had to set the lexer after the file was opened. It still didn't work. Sorry
to be such a noob, but is there something I am missing that will tell the lexer
to start lexing? I took a look at the setLexer method of the QsciScintilla
class and couldn't see anything that my simple code was missing, but am clearly
wrong somehow.
