Re: [fltk.general] Clickable URLs in text
I was making sure last line was visible when appending a new line if the last line was already visible. When i got a few hundred lines i noticed my app took increasingly more cpu appending new lines. From a user perspective it was fine but i was not happy with cpu usage (i went with fltk for fast and light). I have to admit that i did not examine if there was a better way than show_insert_position to do this. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
Re: [fltk.general] Clickable URLs in text
I replaced Fl_Text_Display with a specialized Fl_Browser for now. For now i just check for http:// links when i double-click a row and use xdg-open to open that link in browser. For actually opening the link, fl_open_uri() might help - it works on non-xdg platforms too, but essentially does xdg-open on linux-like hosts...

I'm curious: What specifically was slow in Fl_Text_Display (scrolling, adding text, parsing..) How much text (approx) was involved? Which FLTK version are you using? (1.3.0, 1.3.x svn current, 1.3.x r..) I've had really good performance with Fl_Text_Display on large files. Just now my Fl_Text_Display widget loaded a 4MB text file with 65000 lines in under a second over a network connection, and I can scroll back and forth from one end of the file insanely fast.. it could not be faster. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk

Re: [fltk.general] Clickable URLs in text
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. Any ideas are very welcome. ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk

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. That might indentify where the CPU is going? SELEX Galileo Ltd Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England Wales.

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

Is there a way to make clickable links in text ? No, there's no way, at least not in Fl_Text_Display. The only widget supporting clickable links I know about is Fl_Help_View, a somewhat limited HTML display widget. Maybe this is what you need. Otherwise, you'd have to derive your own widget(s) to allow clickable links. I'm thinking of deriving from Fl_Box to make the label inside the box clickable. You may need to make your own draw() method (or maybe not), and you can do highlighting when the cursor is over the link. However, this needs some programming in the handle() method of the derived widget. If you need more help on this, please describe better what you want to do, maybe we can then find a better way to achieve it. There were some add-on widget sets (I'm thinking of FLU maybe Matt's FL_MM stuff) that provided buttons that appeared as clickable links but, as Albrecht said, I think the only widget we have for doing this in body-text is the help_view. As an aside, once you have your link working, the fl_open_uri() functions might be useful - or not, depending on what you really want to do! I just did a quick and dirty test on Fl_Button, just set button-box(FL_NO_BOX); and also the callback to . ___ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
