Are there any good GUIs that support pygame surfaces as a widget within the application? If this isn't possible or practical, what GUI toolkit has the best graphics component? I'm looking to keep the speedy rendering made possible by a SDL wrapper. ...
I have a class which inherits QAbstractTableModel, and holds some complex structs in a QMap. The QVariant data(QModelIndex index, ...) method just returns an enum which describes how a custom item delegate should draw the contents of a cell. I would like to implement drag and drop functionality in this model so that users can reorder th...
I have a QTableView in which I am displaying a custom model.

I have a form in which I want to periodically refresh its values(mostly labels but 2 comboboxes and 1 spinboxe).

Ideall...

I have a method which is called from both QThreads and the main thread. this method can sometimes take a long time to do its computations in a loop so I put QCoreApplication::processEvents() and this prevents the GUI from freezing.

I would like to unpack this data in an overloaded dropMimeData() function, but can't figure out how to convert this QMimeData back into a QModelIndexList. I tried the obviou...
