    Default QTableView and QAbstractTableModel programming

    I have successfully created code that loads and displays data in a QTableView with a QAbstractTableModel.

    I have done so by piecing together a LOT of bits from around the web. And I would really like to find some discussion of the concepts of table views and models...I really find the complexity of displaying a table of data with this construct mind numbing. I be happy to go read any recommendations. Or if anyone can recommend any tutorials or examples?

    That said, what I really need to do now is add code that sets the color of a row. For example the color of the row indicates the function of the displayed data. So each row may be one of 4 or 5 colors.

    So far, setBackgroundColor doesn't seem to be the answer...

    I'm using PyQt5.

    Look at QAbstractTableModel::data method, specifically for the Qt::BackgroundRole.
    I write the best type of code possible, code that I want to write, not code that someone tells me to write!

    Mark Summerfield's book "Advanced Qt Programming" has nearly 200 pages on models, views, delegates, and other things associated with the Model / View architecture. It is a few years old and is based on Qt4, but the M/V architecture is not much different in Qt5. Unfortunately, it is all C++, but the mapping to Python is not so hard.

    He also has another book, "Rapid GUI Programming with Python and Qt", also PyQt4-based, but it does not have as much material on M/V.

    He's a good author, books are easy to read and understand. I found the first book particularly helpful in understanding tree models, especially using them with proxies.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.
