Hi there, Here comes the rest of the story, and the steps we're taking.

Devid, you're surely in a better position to judge the legal aspect of using the May version of the license. At least you can ask Debian legal! If that's enough to get FLTK2 packaged, we can push it forward this way. If not, I can talk the problem with the fltk-1.3 development team, try to get a release estimation date and speed up the port to fltk-1.3 accordingly. AFAIU the 1.3 branch has no license issues. I'll be expecting your answer to get back to fltk devs. TIA. -- Cheers Jorge.-

The other way they describe uses Javascript. But it would also be possible to make links visible/invisible depending on whether the user has visited a site (see below). From what the user then clicks one might get a clue about his browser history. But this is not automatic and only one piece of history information per click.

perhaps an iterator bug

At the time, I didn't recognize what the exact problem was. Now it dawns on me that the difference is really that line 2's text has whitespace before the next tag, and line 3's doesn't. It would be nice if the iterators thought of cells as being separated by whitespace, but I don't know yet whether there's a good and simple way to do that...

Hi, this http://wtikay.com/docs/details.html is quite interesting. Dillo is not vulnerable, but we should keep this in mind when implementing background image support. Cheers, Johannes

Any idea why? Actually, I made a patch for that last night (attached). getAllocation() determines the boundaries and position of a Word, and then Iterator's scrollTo() figures out how to place it. But for plain text, the whole line is a Word, so scrollTo was just positioning the line as a whole and considering its work done. In the patch, I take start and end into account to figure out what part of the Word we really want to see. (The current behaviour of showing the whole word is a little bit nicer for html with "normal"-sized Words, but...)

horizontal scrolling while searching

by Johannes.Hofmann＠gmx.de

corvid, you have just fixed an issue with horizontal scrolling during search. While testing it I realized, that horizontal scrolling during search does not work at all with plain text. Any idea why? Cheers, Johannes

Ok fix committed. This took a lot longer than expected. I almost had full polygon clipping implemented which is quite complex, until I realized that it is much simpler to change Style::drawBorder() to use rectangles and triangles instead of a single polygon for each side. That way we can easily clip the large part of the border (the rectangle) and avoid X11 coordinate overflows. It also seems that this makes dillo a bit snappier. Cheers, Johannes
