Hello,

I played with ClaudeAI and asked him to make a HtmlViewer for U++ using litehtml
https://github.com/litehtml

Here is what I got

/forums/index.php?t=getfile&id=7152&private=0

In the url bar you can set the pat of a local file and it is nicely rendered.
The problem is that it works only in debug mode. If I switch to release mode some bad thing happens and the program cannot retrieve properly the font size. Why this happen is beyond my capability and even beyond ClaudeAI knowledge. We did some LOG to analyze the output and he concluded that in release mode the font dimension are not returned properly. It tried many fix but no results.

This experiment is very promising. If fixed I (ClaudeAI) can add a HTTP support to retrieve page online. But even so as simpler HTML viewer would be very useful... at leat for me to visualize a better report with HTML table.
In the next post I am going to attach the package I used with few instructions.

Thanks,
Luigi

Attached the package that contains the folder lithehtml.

In the include directory add these paths:

C:\Users\forla\Documents\MyAppsExp\LHUpp\litehtml\src\gumbo\ include
C:\Users\forla\Documents\MyAppsExp\LHUpp\litehtml\src\gumbo\ include\gumbo
C:\Users\forla\Documents\MyAppsExp\LHUpp\litehtml\include
C:\Users\forla\Documents\MyAppsExp\LHUpp\litehtml\include\li tehtml

I used the U++ 18518

Thanks,
Luigi
