I am having problems with rendering HTML (Rich Text) in PyQt. I am using PyQt-Py2.6-gpl-4.4.4-2 with Python 2.6.1.
These errors show up with any widget that can display Rich Text.
For my HTML display example I am using a QTextBrowser.
The problems involve incorrect closing of various tags. Even more
strange is that the behavior is different if I use
QTextBrowser.setHtml() or QTextBrowser.setSource().
For the example that I am attaching below there are two errors.
1. The <div> tags around the title are not being closed until after
the next line of text.
2. The list is not closed until the end of the file (<ol> and <li> tags).
Problem #1 happens with both setHtml() and setSource().
Problem #2 happens only with setSource.
Clicking on a link has equivalent behavior to using setSource()
Both the display of the HTML in the widget, and the output from
QTextBrowser.toHtml() are incorrect.
I do not know if this is a Qt or a PyQt issue, but I thought I would
ask for help here first.
Included at the bottom of this message is a representative program and
the output (simplified).
Attached is the program and output (raw).
Thanks in advance for any help.
