2016年12月14日 · I'm looking for the easiest way to display a simple html file (just a long html-formatted text) inside the Qt dialog. Links, if any, should be opened in the external default system browser.

2018年3月12日 · You can't use an XML parser for HTML. You either use htmlcxx or convert the HTML to valid XML. Then you are free to use QDomDocument, Qt XML parsers, etc. QWebEngine has also parsing functionality, but brings a large overhead with the application.

2021年8月8日 · It does indeed seem possible now that Qt supports WebAssembly. Qt 6.4 now offers support for WebAssembly, and their website has various examples of apps built with Qt that run in the browser: Qt WebAssembly Demos & Examples

2009年12月24日 · The Qt API is ludicrous. In 2019, this should be built-in functionality. When every Qt application that wants to format item text ( ...which, let's face it, is most of them ) needs to manually reimplement non-trivial item delegates that no one appears to have successfully implemented in a general-purpose manner, something has gone profoundly awry.

2014年7月26日 · Yes, I agree that introducing undefined behavior into your application is easy. That doesn't mean you should do it. Qt makes asynchronous coding relatively easy thanks to signals/slots even in Qt 4. With C++11 and Qt 5 there's really zero excuse to suggesting spinning local event loops and similar craziness. –

2016年9月5日 · I try to programmatically generate HTML using Qt 5.7 and C++. I would like to avoid using simple text streaming since this does not check HTML syntax. I tried to use QTextDocument and toHtml() but it seems not to work very well. It generally supports a small HTML subset only and a lot of standard elements must still be coded into strings manually.

2015年3月11日 · I have a QTextEdit where I do display some HTML. Could I apply a stylesheet to that very HTML content? Do not confuse it with applying a Qt stylesheet to the QTextEdit (that I know). I want to change the appearance of what is in the QTextEdit widget ("HTML"). Related: Default HTML style for controls in the Qt library

2013年6月4日 · The Qt::convertFromPlainText function (also mentioned by Amartel) still exists in Qt 5, but it does more than PHP's htmlspecialchars. Not only it replaces < with &lt; , > with &gt; , & with &amp; , " with &quot; but also does additional handling of whitespace characters (space, tab, line feed, etc) to make the generated HTML look visually ...

2016年7月1日 · As far as I'm aware Qt has no HTML parser (only an XML parser, but all valid HTML isn't necessarily valid XML), so the easiest is probably to use a third-party HTML parser such as Lexbor. – Donald Duck is with Ukraine
