Detailed Description

The TextHTMLBuilder creates a clean html markup output.

This class creates html output which is as minimal as possible and restricted to the rich text features supported in Qt. (https://doc.qt.io/qt-5/richtext-html-subset.html)

The output contains only the body content, not the head element or other metadata.

eg:

<p>
This is some <strong>formatted content</strong> in a paragraph.
</p>

instead of the content produced by Qt:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN"
"http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><meta
http-equiv="Content-Type" content="text/html; charset=UTF-8" /><style
type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'Sans Serif'; font-size:10pt;
font-weight:400; font-style:normal;">
<p style=" margin-top:12px; margin-bottom:12px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">This is some <span
style=" font-weight:600;">formatted content</span> in a paragraph.
</p></body></html>

Such tags should be created separately. For example:

auto b = new TextHTMLBuilder();
auto md = new MarkupDirector(b);
md->constructContent();
QString cleanHtml(
"<head>\n<title>%1</title>\n</head>\n<body>%2</body>\n</html>")
.arg(document.metaInformation(QTextDocument::DocumentTitle))
.arg(b->getOutput());
file.write(cleanHtml);
KPIMTextEdit::MarkupDirector
Instructs a builder object to create markup output.
Definition markupdirector.h:76
KPIMTextEdit::TextHTMLBuilder
The TextHTMLBuilder creates a clean html markup output.
Definition texthtmlbuilder.h:86
QString::arg
QString arg(Args &&... args) const const

Font formatting information on elements is represented by individual span elements.

eg:

<span style"color:blue;">
<span style="background-color:red;">
Blue text on red background
</span>
</span>

instead of

<span style="color:blue;background-color:red;">
Blue text on red background
</span>

It my be possible to change this if necessary.
