There are two parts that I have been able to find. Part 1 worked fine, and I'm now working on Part 2, how...
I would like a web interface for a user to describe a one-dimensional real-valued function. I'm imagining the user being presented with a blank pair of axes and they can click anywhere to create points that are thick and draggable. Double-clicking a point, let's say, makes it disappear. The actual function should be shown in real time...

This question is about keeping the GUI responsive during longer-running tasks (a few seconds in most cases). I extensively use threads and a task pattern to execute expensive task in a background thread. But what about GUI updates that takes some time? For example, filling a large string grid or tree view? A thread does not help here be...

Then I thought f m...

I have a large cross-platform (Linux and Windows) C++ project, for which I want to create a GUI. I have few very general questions about the basic principles of GUI for such project: Should the GUI be separated from the application's logic? If it is separated, how should the logic and the GUI communicate? Are TCP/IP sockets a good opt...
