Suggestions for streaming large data set
I'm currently working on an application that visualising a large streaming data set. The Item data it self is small (Several columns with numbers and strings), but I have several millions of them streaming to my application via shared memory. Im using Boost's Interprocess MessageQueue to receive the data. I can use blocking and non-blocking variants of message receiving methods.
I would like to present this data in a TreeView, each row representing an input data from stream. Also I would like to provide functionality for expanding items (+) and generating (requires some small search and data generation) additional hierarchical data related to that item.
I want to design the application in the MVC pattern; I have a decoupled model (QAbstractTableModel) and a view (QTreeViewtreeView).
I would love to know how experienced Qt developers would integrate my streaming data, model and view.
I have a setup with CMake 3.1.3, Qt 5.6.1.
Hi @GrandCentralDispatch , and welcome to the Qt Dev Net!
The first thing I suggest is to work through the Fetch More Example: http://doc.qt.io/qt-5/qtwidgets-itemviews-fetchmore-example.html . Let your model load your data bit by bit, instead of all at once.
