Thanks all for replying. I saw your replies now since i did expect a mail telling me i got replys ... seems this is a very primitive forum :). I am using a Fl_Text_Display to display a game lobby chat log, often http URLs are written by the "host" in this chat log and i want to make it easy for the user to go to these web pages. Sounds like i will have to specialize Fl_Text_display or perhaps make my own widget. I have considered making my own widget since i feel Fl_Text_Display is a bit of a cpu hog.

I don't think I'd use a text display for that at all, I think I'd use a Fl_Browser, and derive from that to get the desired behaviour. Though if you need anything more than very basic text handling, maybe Fl_Text_* is the way to go. That said, IIRC Greg had an example of a simple chat widget on his cheat-sheet, maybe that might be useful to you? I'm surprised you think it's a CPU hog - it's derived form the old nedit codebase, and is generally OK. Do you have metrics showing the loading and utilisation.

Hmm, don't think I made a chatter in FLTK. I did make a telnet based chat: http://seriss.com/people/erco/unixtools/talkerco and a browser based web chat: http://seriss.com/people/erco/unixtools/chatter Perhaps you're thinking of a dumb terminal emulator that lets one type commands that run in a shell and see the stdout/err of the commands in an FLTK window: http://seriss.com/people/erco/fltk/#SimpleTerminal In that case I did use Fl_Text_Editor. I haven't really seen cpu issues with it, but I suppose it depends how you make use of it. I see the subject of this thread being URLs in text, which might mean the FLTK html widget is involved. That may have speed issues, as I think it has to re-parse everything when changes are made. If I needed a chat program that allowed URLs to be automatically clickable, hmm, yeah, might have to customize Fl_Text_* to do that. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
[fltk.general] Context Highlighter?
Hi all, I think there is a good project for an FLTK application in my work, The account managers have to analyse reams of output from the client's particular 'calculation code' and config which is written in an in-house interpreted language. The thing is there is nothing to support this analysis other than using the 'find' function in whatever viewer they open the reports in. So my idea is to write a custom viewer with FLTK to provide at least context highlighting as an initial aid. The reports contain a range of datatype labels such as ' int ' and also 'blocks' of relevant procedures, comments etc. I would welcome any suggestions regarding a starting point in FLTK for this 'viewer'. The text editor perhaps? bearing in mind i only want read functionality. Identifying 'start /end' to statement blocks etc, Colouring text if it is a certain dataype, etc. background highlighting of text when the context is of a certain statement type, all of that kind of thing. Can the text editor be tweaked in this way? Thanjks for any info. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk

The text editor already supports colors very easily. See this simple example: http://seriss.com/people/erco/fltk/#Fl_Text_DisplayStyle You can specify an optional 'style buffer' to the Fl_Text_* widget which parallels the 'text buffer'. Each byte in the 'style buffer' is an index into a 'style array' that defines the color, font face, and font size of each corresponding character in the 'text buffer'. FLTK's own code editor (within fluid) makes use of this feature to enable syntax highlighting of the C++ code, so that code is syntax-colored as you type. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk

Thats great, thanks a lot, I knew i was being a bit lazy asking
directly without checking first there, but carpe diem... and all that..
One thing though is i think a background highlighting effect would
be nice, like if it was in notepad++ and you wrote some bash stuff:
a statement like: var=${#fNames[*]} would have a light colour to the
text background in the curly braces.
Like i say, i am not directly checking up on this right now, apologies!
I just assume FLTK will easily support this type of thing also.
The only other thing i would say is my initial idea, and certainly for
simplicity is to not allow writing. Would i be better to start code
with a widget other than text editor in this case?

Greg, thanks, I checked your page link, also in relation to the fluid code view i see exactly what you mean, and also there is no write enabled! That would be a real improvement on the current view the consultants have. One thing though is what are the limits on the buffer. I know from a meeting earlier that there may be 3000 pages, but that would be a real exception rather than the rule.

Adding background colors to Fl_Text_* might be easy, not sure.
You'd basically add a new background color field to the style class,
and if it's anything other than the widget's bgcolor, you'd first
draw a filled rectangle in the new color before drawing the text
over it.
Fl_Browser has some color abilities, but the built in stuff
is limited to color and font for the entire line, IIRC.
Some time ago I posted a small patch for Fl_Browser that
enables ANSI sequences (similar to Xterm terminal color codes)
so that one can change the color and font on a per-character basis.
See: http://fltk.org/newsgroups.php?gfltk.development+v:5540
A screenshot from the patch's test program:
http://seriss.com/people/erco/fltk/tmp/Fl_Browser-ansi-test.png
However, Fl_Browser is not really optimal for general text presentation;
you can only highlight entire lines, not individual characters.
Therefore, it's probably best to tweak Fl_Text_* to your liking.
Just take a copy of FLTK's code for that widget, change the name
of the classes, then customize to taste and use in your own app.
Post the code when you have something working, as we might want
to merge it into the existing widget.

That would be a real improvement on the current > view the consultants have. Right; the example there uses "Fl_Text_Display", which is read-only. (ie. you can't type into it) Not that you sound like you need it, but if you wanted it to be more like an 'editor' where user's can type, you can just change "Fl_Text_Display" to "Fl_Text_Editor", and you can then also type into it. > One thing though is what are the limits on the buffer.

I believe it will basically load whatever you tell it to, the practical limit being the machine's ability to allocate memory. I'm not sure if there are performance limits at very high values, but I know I've used Fl_Text_Display on very large several hundred megabytes, and not seen a problem with speed.

Isn't there even an easy example in the docs? I did such a thing in my commercial app. by subclassing Fl_Text_Display. The nice thing is that you can add another text buffer, fill it with anything you like, and then switch buffers (show the alternate buffer in the widget) with the text you want to show. This could be a list of all lines matching a search (that's one of the features I used). Together with the (syntax) highlighting features described by Greg (see also test/editor.cxx), this is very powerful for self-written analysis. Hint: run "test/editor test/editor.cxx" to see the editor working with syntax highlighting. It's a real editor, you can use it for editing source files ;-) and it has search and replace functions.

Thanks for the info there, I am wondering though in the extended case of this idea would I be getting into regular expressions as an ideal text handling method?
