Hello, I am trying to use GetStringWidth() in wxPdfDocument and I was expecting the line drawn to be the same length as the text. Does anyone know what I am doing wrong? Yes.

What is the best way to create a table that say consists of 3 columns: Name char, Price real, Qty real I don't see where this could be done using wxSqlite3 unless I'm missing something.

A subset exposing the problem you observed would be enough, of course. Maybe you can pack the files into a zip archive, upload them and send a link for ...

With wxPDFDocument lib i add in a file many pdfs. Size too big, about 700MB in almost 800 pages. Ok so far. In principle, the final PDF file should only be slightly larger than the sum of the sizes of the inserted PDFs. However, it also depends a bit on the settings for wxPdfDocument (for example, ...

I applied a fix for the issue on importing a completely empty page.

However, meth...
