a Text Editor with line numbers...

[fullmetalcoder]

I use "kwrite" or "kate"

lol
You don't seem to pay attention to profile on the right of each post! I'm a Windows user, even if I would like to change there's no way, other users would'nt agree!

Again, a few questions if you do not mind:
1) "display tab as X spaces", did you implement it? If so how? if not, how are you planning?
2) The syntax highlighter. It's based on the examples from the trolls? See notes bellow.
3) Current line and match brackets. Planned...? Implemented...?

[...]

If found that using RegEx for for the painting is extreamly painfull, as in big files (~1000 lines) text will take about 5 seconds to load. I will try to see if the code for settign the QSyntaxHighliter can be put in a QTimer::singleShot() to make this call asynchroneous and improove usability, as hack for a good SH system.

Did you write the SH yourself (as the example on Qt4.0 showed), or are you deriving QSyntaxHihlighter. In any case, how is the drawing made? (hard coded contexts or something like Kate?)

I don' mind!

1) three ways:
- either reimplementing the whole paint event which may be very hard.
- either using each time font gets modified :

setTabStopWidth( x * QFontMetrics( font() ).width(' ') );

setTabStopWidth( x * QFontMetrics( font() ).width(' ') );

To copy to clipboard, switch view to plain text mode 

- either hacking the keypress event so that any tab char is translated as x spaces [pretty uggly and stupid]

2)Sure it is! Actually I took the reimplementation from QSA and subclassed it as C++ syntax highlighter. Yes it's based on QRegExp which is an inherently slow method with large files but, well...

3)What do you call current line? Isn't that implemented in two ways?
What do you call match bracket? Indentation? Indentation is planned but not that easy!
There was a "parenthesis matcher" in QSA code but I didn't understand it's goal so I removed it!

1) Please, don't reimplement the drawing engine. I am not a native english speaker. My native language is Spanish, but since I live in Israel, my real language is Hebrew - which as you may know already it's a complex script (google for RTL or BIDI).

If you reimplement the drawing code of the QTextEdit, you will loose any BiDI support in that widget. You will probably mess up Chinese, Hindic, and some other languages which Lars has worked so hard to get in perfect shape.

The setTabStopWidth() seems to beright way. As you will be able to convert the tab to "spaces" and back. This means you do not mess with the text the use loaded.

2) Reguarding the SH, I will see if there is a way to set it in a callback or something, otherwise th UI gets frezzed for several seconds when the initial painting is done. I also found no eay to rehighlight the code (what if the user wants to use another highlight...?)

3) current line = current pararaph in QTextDocument terminology. I want to draw the current line with a different background.

When the cursor is on "}", that char should be drawed with another background color, and the same for the first "{".

I assume you support only C/C++/H files right now...?

It's planned but not working right now.

Would be quite hard!!!

Entierely true.

Due to the limitations of my wrapper around QTextEdit I started porting QScintilla to Qt4.
Pretty long and hard as I never learned Qt3!

Yea, i played with porting QScintilla to Qt4. Of course if qt3to4 did all the work, it would be too easy, but there is still tons of hand-massaging you have to do. Porting from scratch using Riverbank's code as a guideline might in the end be the best way to go.

Where to find Riverbak's code? Would be happy to find an easy way!!!

QScintilla does not support anything but Latin1 and thus it's unusable for me and many others.

[fullmetalcoder]

I ported QScintilla by hand from Qt3 to Qt4, it compiled without even one warning.
I then tried to use it in a very simple program and it linked with no problem, the window appeared...
but not the cursor
then tryed to copy from another editor... NO WAY!!! but the context menu displayed...
then tryed to typoe by hand a few words... NO WAY!!! What the fuck is that???
I spent 4hours porting something that doesn't work!!!

release the code or shut up...

at last for the first editor!

[fullmetalcoder]

which code??? buggy QScintilla or working QTextEdit???

QTextEdit based now highlight current line in cyan but there's still a twist:
no simple way to make it highlight the whole line, as in Dev-C++ for example.
any ideas on how to do that?

cheers

I would like to see a code based on QTextEdit, because of the reasons I explained before. But that's me

[fullmetalcoder]

I should be able to post it tomorrow.

No solutions comes to me about current line colouring but I implemented the basis of a breakpoint management system.

Seems to progress!!!

If you want to see more information on scintilla implementations, you may want to check out:

http://www.codeproject.com

and search for "scintilla". Of course these will be implemented with MFC or in C#, but you might get some ideas.

P.S. CodeProject's search isn't very good; you'll get more hits googling the CodeProject site.

You said tomorrow on the 22, now it's 24.

SHOW ME THE MONEY!

Now I do see the code...
comments tomrrow... /me shuts up now.

Hi! And where is the code?
All of us want to have a look at it...
Thanks.

QTextEdit was not really designed to be an editor. The best thing to do to make a good editor is make one from scratch using parts of Qt's code as a baseline That's what I am doing currently
