Hello Luigi,

The true thing is that HTML view control is one of the most important think we need at the moment. Please noticed that sometime ago Zbych implemented ChromiumBrowser. Currently, it is available only in upp/archieve repository, not UppHub. It is basing on CEF (Chromium Embedded Framework), Personally, I would do not go for lite-browser, because the whole library looks like a niche for me with poor support. It means that security norms will not be meet, which are crucial in context of applications that renders HTML and executes JavaScript.

If, we look for our competitors such as QT, the have QTWebEngine that is basing on CEF. We should aim for similar thing.

Since the implementation is not trivial and the maintenance cost will be high. Providing this functionality for U++ is a challenge not for one person, but for a group of people. So, before starting working on that it would be good if you will find somebody that will help you!

Hi,

In case you've missed it, we already have a fully functional html-5 parser (and sanitizer/prettifier as a bonus) now.
(Of course, I am aware that Mirek's code serves another purpose, but a fully-fledged HTML->QTF converter, using HtmlTools package would too be very easy to implement.)

Accidentally, I was forced to implement limited support for RichEdit accepting HTML clipboard format.

While definitely not the same thing as HTML viewer, it now understand most of style formatting that is applicable to RichText. I plan to enrich it a bit more (to actually understand CSS, add support for tables and maybe some sort of support for importing images).

https://github.com/ultimatepp/ultimatepp/blob/master/uppsrc/ RichText/ParseHTML.cpp

(That is not meant to distract us from CEF, ParseHTML is not even meant to be complete HTML viewer, just a bridge that allows some HTML->RichText/QTF conversion)

Hi Mirek,

even this may help a lot.
Is there an example package that shows how to use it or it should work as paste operation from clipboard?

Thanks,
Luigi

Yes, I missed it.

I downloaded the code and extracted HtmlTools and HtmlToolsExample package in MyApps folder, but theide (16879) doesn't list them Rolling Eyes
Do I need to do something else before to compile them?

Parsing HTML is (relatively) easy. Where it gets hard IMO is where you have to interpret styles to have some meaningful rendering info. Font sizes, colors, line styles and width and such.. I have not checked too deeply, but few examples I have seen do not seem to deal with that stuff at all...
