Lightweight HTML/CSS rendering engine written in pure Free Pascal

Please make an announce of the new component at

It must be visible very good.

Really impressive, thank you!

Fixed a couple of compilation errors with older FPC, added interactive scrollbar and Qt5/6 backend.

Adding any scripting is currently not planned (what for? any kind of host app interaction comes back to the Lazarus/Pascal app).

Thank you for Retrofoxed's efforts!
Great! The scroll bar is now available. It would be great if there were an onScript callback like in THtmlViewer.
For example:
procedure TForm1.HtmlViewer1Script(Sender: TObject; const Name, ContentType,
Src, Script: ThtString);
begin

end;
Of course, it would be even more complete if it were directly integrated with JavaScript support.

What's your exact use case for this? I can understand why JS access would be needed for web-sites, but this isn't really a web browser (so far :-D) capable of surfing web-sites. In other words, how do you intend to use it?

All I can say is that this is pretty impressive work !

Would be great to see if it can be integrated into the CHM viewer.

Good luck with that one. This came up with IPro versus THtmlViewer - and that didn't go anywhere.

Do you know what exactly caused the problems ?

Thank you! This is really great, cool, sweet and nice! Will you be able to support FMX as well as VCL? iOS, iPadOS and Android support through FMX would be the icing on the cake

Inertia.

Current code saves tag names to str fields, right? e.g. 'img'. I got a small idea: save not the str field but enum field, calculated from str. Will it make work faster?

Great idea — and actually, Pixie already does exactly this! 🌟 Tag names are converted to integer IDs during parsing (via PixieId()), so internally the engine never compares strings like 'img' or 'div'. All tag matching uses fast integer comparisons instead.

The string-to-integer conversion happens just once when the HTML is parsed, and after that everything runs on plain numbers. This optimisation is already in place :-)

Yes, actually I already have a working FMX prototype. I can only test on Windows/macOS though - it'll be up to you guys to test on mobile platforms.

But it should work universally as FMX abstracts any target platform.

[ALLIGATOR]

Maybe someone could port (adapt the canvas backend) it to Android?
(Using the Android NDK, following a similar approach to the one described here:
https://github.com/VadimBoev/FlappyBird
https://github.com/cnlohr/rawdrawandroid
&
LAMW
)

Just an idea (I'm not ready for that myself yet)

Nice 👍🏻

I suppose «contenteditable» for rich text editing will be quite hard to implement?!
