In my project, I have a set of DLLs I want to load delayed, i.e. on first use instead of on process start. That means I want to use /DELAYLOAD flag of the MSVC linker (see [1] for more explanation) for certain DLLs (not Qt itself). The reason is that some users experience crashes during DLL initilization (which we can't reproduce). A fo...

I've given up on actually trying to make it go faster. My biggest problem is that when I'm inserting the html, the application slows down to a crawl. I have a progressbar, and I'm calling QCoreApplication.processEvents() (I'm using pyqt, by the way) Can I put insertHtml() into a different thread, so I don't have an unresponsive in...

What I need is...

I'm building a small multithreaded web server. The QTcpSockets are fetched in the main thread and then hand over by QtConcurrent to the QThreadPool, which eventually processes the data and sends out an answer. My problem is that the socket is created in the main thread and processed in another one. This causes errors when trying to writ...
