There are two redrawing problems: If I try http://earthquake.usgs.gov/earthquakes/recenteqsww/ a little bit of the map is visible at the bottom of the viewport initially (geometry 850x630). The rectangles are visible, but not the polygons. If I page down or switch to another desktop and back, all is well. If I try http://www.sbrady.com/hotsource/html/imgmaps.html because it has bigger rectangles, when I scroll line by line, I get lines in my rectangle corresponding to the edge of the view. No problem with circles or polygons. All I'm doing is calling the fltk shape-drawing code through fltkviewbase, so I'd expect them all to work or break in the same way. I will probably change FltkViewBase::drawArc() so that (x,y) is the center like one would expect. That tricked me at first, and I might have been the one who wrote that code in the first place. I might make an additional FltkViewBase::drawPolygon() that accepts the SimpleVector of points and then calls addvertex() a lot rather than one addvertices() call. Slower, but they're just image maps, and the pointArray in Polygon::draw() here is too complicated (I had to look it up to get it quite right). -------------- next part -------------- diff -r 3d9a1b463163 dw/image.cc --- a/dw/image.cc Fri Mar 05 00:54:54 2010 +0000 +++ b/dw/image.cc Sat Mar 06 00:39:34 2010 +0000 @@ -38,6 +38,18 @@ delete shapesAndLinks; } +void ImageMapsList::ImageMap::draw (core::View *view,core::style::Style *style, + int x, int y) +{ + container::typed::Iterator it; + + for (it = shapesAndLinks->iterator (); it.hasNext (); ) { + ShapeAndLink *shapeAndLink = it.getNext (); + + shapeAndLink->shape->draw(view, style, x, y); + } +} + void ImageMapsList::ImageMap::add (core::Shape *shape, int link) { ShapeAndLink *shapeAndLink = new ShapeAndLink (); shapeAndLink->shape = shape; @@ -105,6 +117,15 @@ currentMap->setDefaultLink (link); } +void ImageMapsList::drawMap (lout::object::Object *key, core::View *view, + core::style::Style *style, int x, int y) +{ + ImageMap *map = imageMaps->get (key); + + if (map) + map->draw(view, style, x, y); +} + int ImageMapsList::link (object::Object *key, int x, int y) { int link = -1; @@ -348,12 +369,17 @@ intersection.x - dx, intersection.y - dy, intersection.width, intersection.height); } else { + core::View *clippingView; + if (altText && altText[0]) { + core::View *usedView = view; + + clippingView = NULL; + if (altTextWidth == -1) altTextWidth = layout->textWidth (getStyle()->font, altText, strlen (altText)); - core::View *clippingView = NULL, *usedView = view; if ((getContentWidth() < altTextWidth) || (getContentHeight() < getStyle()->font->ascent + getStyle()->font->descent)) { @@ -374,6 +400,18 @@ if (clippingView) view->mergeClippingView (clippingView); } + if (mapKey) { + clippingView = view->getClippingView (allocation.x + + getStyle()->boxOffsetX (), + allocation.y + + getStyle()->boxOffsetY (), + getContentWidth(), + getContentHeight()); + mapList->drawMap(mapKey, clippingView, getStyle(), + allocation.x + getStyle()->boxOffsetX (), + allocation.y + getStyle()->boxOffsetY ()); + view->mergeClippingView (clippingView); + } } /** TODO: draw selection */ diff -r 3d9a1b463163 dw/image.hh --- a/dw/image.hh Fri Mar 05 00:54:54 2010 +0000 +++ b/dw/image.hh Sat Mar 06 00:39:34 2010 +0000 @@ -39,6 +39,7 @@ ImageMap (); ~ImageMap (); + void draw (core::View *view, core::style::Style *style, int x, int y); void add (core::Shape *shape, int link); void setDefaultLink (int link) { defaultLink = link; }; int link (int x, int y); @@ -55,6 +56,8 @@ void startNewMap (lout::object::Object *key); void addShapeToCurrentMap (core::Shape *shape, int link); void setCurrentMapDefaultLink (int link); + void drawMap(lout::object::Object *key, core::View *view, + core::style::Style *style, int x, int y); int link (lout::object::Object *key, int x, int y); }; diff -r 3d9a1b463163 dw/types.cc --- a/dw/types.cc Fri Mar 05 00:54:54 2010 +0000 +++ b/dw/types.cc Sat Mar 06 00:39:34 2010 +0000 @@ -35,6 +35,17 @@ this->height = height; } +/* + * Draw rectangle in view relative to point (x,y). + */ +void Rectangle::draw (core::View *view, core::style::Style *style, int x,int y) +{ + const bool filled = false; + + view->drawRectangle(style->color, core::style::Color::SHADING_NORMAL,filled, + x + this->x, y + this->y, this->width, this->height); +} + /** * Return whether this rectangle and otherRect intersect.

I am trying to simulate a working Dillo on my desktop before moving the same to my ARM based Embedded Platform. Presently, I am able to run Dillo and browse web pages. However this requires use of Mouse. I would like to eliminate mouse and use only keyboard. Further, I would like the LEFT/RIGHT arrow keys on my keyboard to move to a previous/next link on the currently opened web page. Further, I would like that upon pressing "ENTER" key at this time, the previously selected link is opened. Basically, I would like to use LEFT/RIGHT and ENTER keys to navigate through an already opened web page (Without Mouse). Can any body please help me how to achieve this using Dillo.

Open source software is free software, and that means people aren't paying for it, and, annoyingly enough, people are too lazy to RTFM and expect you to answer their email with their support concern or implement whatever pet feature they want "for fun and for free". A lot of web boards out there are filled with free software users with a pretty strong "entitlement mentality"; people who don't contribute to open source but think open source developers should give them a program with the features they want without being paid a cent for their hard work. I have blogged about this quite a bit: http://maradns.blogspot.com/search/label/freetards The way I handle people like that is by making it crystal clear I do not provide unpaid email support; if you want private email support, have your credit card ready. Some people ignore all of the warnings on the web page with my email address so I have a simple script which sends people like that a canned reply asking for money and telling them I will forward any further email they send me to a public mailing list unless they have already paid me. When people ask for features, I handle them in email by giving them the canned reply; if they request features on the mailing list, I ask them how much they are willing to pay for said feature, or give them the "I'm married and don't have time to implement more features for free" spiel. If you know of a way I can keep my program open source and make money on it, I am all ears. I have made a little money implementing features people want, but not nearly enough to pay the rent. It's mainly a way of putting up a boundary with users who want me to go broke programming for them for the rest of my life without me ever getting paid for my work. - Sam From spell_gooder_now at spellingbeewinnars.org Mon Mar 8 15:37:39 2010 From: spell_gooder_now at spellingbeewinnars.org (Patrick) Date: Mon Mar 8 15:38:23 2010 Subject: [Dillo-dev] experiment feedback In-Reply-To: <7bd685721003080609q58254574u8ec3c0e56cfc6138@mail.gmail.com> References: <4B930103.2000909@spellingbeewinnars.org> <7bd685721003080609q58254574u8ec3c0e56cfc6138@mail.gmail.com> Message-ID: <4B950BB3.1090603@spellingbeewinnars.org> Hi Sam I write terrible verbose emails, I did not want to lower the signal-to-noise on the list hopefully this is okay.... My business model follows something like this. I would like to offer scientists tools to control their instruments, plot their data and analyze it. There are already enough open source tools to put something together but it would have to be a pre-fabricated one size fits all solution because these people don't have time to learn to program in C/C++. I was hoping to use HTML as a way to allow the scientists to customize things for themselves. Anyone can pick up HTML in a few days or less, especially with a template. I don't think there is a much of a market helping scientists with HTML. However in order to control their instruments they will need the "command set" to communicate with it. I have lots of expensive proprietary software and instruments too . By eavesdropping on the communication I can recreate the "command sets". It is these commands that are worth paying someone to help with. The software applications this project is trying to replace cost between $5k to 40K. Charging let's say $80-100 an hour would not be unreasonable to come up with a customized solution that eliminates the proprietary software and creates only what the customer needs without bloat. Does this seem logical?

Could something like this be done? Regarding the commercial aspect of the idea I can only say that you need to think at least twice as much about how to actually make money from your idea as you need about the technical details. This will be the hard part... Regarding the technical questions: * For complete CSS 2.1 support, so that dillo would e.g. pass the ACID test I would estimate about 1.5 staff years for a pretty experienced programmer. * For JavaScript support I don't know enough about the details to make an estimation. If you need full CSS support and JavaScript go with an existing compliant solution like webkit. Then if your code works you could come back and check how dillo could be enhanced so it works with dillo too. Do one thing after the other.

I am sure that my business plan will need tweaking but I am also really pretty confident about it. I have spoken with many people working in labs about it and they are really excited about open source. At the end of the day my own business could save 10K a year if I just did not have to buy software and if my project failed to make money but helped those researching diseases and such, that really would not be a loss. " estimate about 1.5 staff years for a pretty experienced programmer" Whoa! I had no idea there was that much work left to me done with CSS. Would this much code change Dillo fundamentally?

There is the whole absolute positioning thing, then there is floats, background images and a lot of tiny details.

I don't think anyone understands all of webkit No need to explain this to me. I use and work on dillo for similar reasons :-) My point was just that * completing full CSS 2.1 support * adding JavaScript * developing your own framework based on that are all very ambitious projects on their own.

Here is a bit more detail if interested. Like most of you I can code an hour or two in the evenings but I am pretty new to C/C++ and will be much slower then the rest of you. I starting working on this project four years ago but this time has been occupied by trying to plan out the project. I feel like I am so close to something amazing but I also feel that I am trying to fit a square peg into a round hole and I am running around in circles. I would like to be able to control and process data from about 100 different models of instruments. I am only working 3 hours a day, while my Autistic Son is in nursery school and looking after him full time otherwise. However I am still able to move about 10-15K worth of instrumentation through my basement per month. I have access to instruments and software, market myself well and have an interest in open source. I feel like I am in a great place to make a difference but I have so far failed to do so. I am afraid to code an entire App. Just the configuration alone would be difficult with so many instruments. I am thinking it might be better to assemble things on a case by case basis. All of these labs have such different needs and styles too, if there was a way they could also write part of the application, that would be best. I know people make hooks in their applications for embedding languages like Lua and Python but these languages will take too long for these busy people to learn, that's why I am looking at an HTML solution. So, what I can offer is 1-2 hours per day of less then amazing C/C++ or I can contribute financially or both. On the financial note, almost all the profit I am making at the moment is back out the door in the form of Autism therapy bills and debt repayment from a difficult couple of years. However my Son is getting better and when I can work a normal work day I should be able to contribute funds, perhaps $100-$300 a month. This is however not enough to employ a full time programmer and I can't fund years of CSS development it would have to be 2/3rds geared towards my project. Not sure if this is a good match for the project?

Ha, that seems to be a problem introduced by my attempt to fix coordinate overflows with huge borders. For borders we always use filled rectangles and for those the problem is invisible. I will fix that somehow.

I started implementing this based on Corvid's suggestion as mentioned under: 1. borrowing from the dw/findtext.cc iteration code. 2. checking when style->x_link != -1 or you're currently on an embedded form widget. I have implemented the first part but still needs test. I have a question while implementing the second part. Can you please tell me how to determine if we are on an embedded form widget currently. Can you please send me code snippets or guide me to implement this ? Thanks. thanks and regards, Rajesh Marathe.

This should be fixed now. The only place where we currently use non-filled rectangles is bullet.cc and indeed I could reproduce the issue with nested
