I'm sometimes considering porting the UI of a relatively complex management app I wrote sometime ago for a small company, from Ext JS to a Python-flavored traditional GUI framework like PyQt (it would essentially become a desktop app powered by an already Python-based backend, which wouldn't be really a problem deployment-wise, as it's an internal-facing app). I think there would be some benefits, but what stops me is a relatively concrete consideration: the primary UI widget on which my app relies are complex data grids, which must support a lot of functionalities (sorting, filtering, etc; which is an area where Ext JS clearly shines), and I'm wondering which framework would offer the best support (in terms of both functionalities and abstractions) for this kind of needs. Any ideas about this?
You can do all those (sorting, filtering, etc) in Qt as well using the Model/View components. There is a bit of a learning curve to understand the "Qt way of doing MVC", but after that it works fine.
At work we use Qt5 with both C++ and Python (through PyQt) and I love it.
Thanks! What I'd like to know more specifically is if there are some ready-made components already packing a lot of these functionalities without needing too much custom logic, or you need to roll out your own from low-level ones?
QTableView supports pretty much everything. Model proxies like QSortFilterProxyModel give sorting and filtering on models not supporting it natively (at a performance cost, i.e. keeping sorting columns in memory).
The model/view components scale to ~infty items, if the model is correctly implemented. They also support lazy loading.
