RichEditCtrl Syntax Highlighting
I wrote this class when I wanted to add syntax highlighting to a utility
that I was writing. I had tried the syntax highlighting classes already
available from CodeGuru and found each one lacking in some way for the
application that I was writing (I was doing some really odd stuff to get
it to work)
I cannot take all the credit though, some of the internal logic came from
Randy More's Colorize class.
To use this class, simple setup you application to use CRichEditView,
then do a search and replace changing CRichEditView to CRichSyntaxView.
If you override OnInitualUpdate I do some initializing there so either
call mine yourself of do similar (or nothing if the defaults are good for
cf.dwMask = CFM_FACE | CFM_BOLD;
cf.dwEffects = 0;
// Set the printing margins (720 twips = 1/2 inch).
SetMargins(CRect(720, 720, 720, 720));
bool LoadKeyWordFile(CString word);
bool LoadKeyWordFile(CStdioFile& file);
Are from the guts of Randy More's control, the CString version calls
the STDIO file version with a handle to the file pointed to by the
void AddComment(LPCTSTR key);
void AddKeyWord(LPCTSTR key);
void AddUserDefined(LPCTSTR key);
Do what they sound like, if you don't want to use a keyword file for
simply want a way to give the user the ability to add things, Comments
are single line comments, KeyWord, and UserDefined are 2 different
COLORREF's with similar logic. This just gives you the ability to
diferenciate between 2 different types(ie. C/C++ keywords and MFC
COLORREF USER_DEFINED, COMMENT, KEYWORD;
USER_DEFINED = RGB(100, 100, 0);
KEYWORD = RGB(0, 0, 200);
COMMENT = RGB(0, 200, 0);
These are the COLOREFS used to set the color of the
keywords/symbols. They are initialized by the default
constructor as shown
void SetFileName(CString word);
Gives you public access to the protected member sFileName, which
is the string used by the OnSave and OnOpen member functions.
These are the logic behind the save and restore mechanism. They
allow you to save the text in the control to a Rich Text Format
file. You need to do any open or save dialogs yourself, they do
not work if sFileName.IsEmpty().
void ParseRange(int iMin, int iMax);
Causes the contents of the control(or a portion of the contents)
to be parsed. Parse() does the whole thing, ParseRange() does a
section(between iMin and iMax, iMin does not have to be less than iMax).
