Qt: QTableWidget/QTableView alternating row colors in full viewport

Question

I have a QTableView containing data rows from a database. However, setting setAlternatingRowColors(true) only alternates row colors that has data - the rest of the table is just white, which is not the behaviour you'd expect (look in the bookmark list of any browser, for example - empty rows has alternating colors).

Does anyone know a workarund or an alternative to the table views supplied by Qt? I've fiddled with stylesheets and item delegates, same result.

Solution 1

Why don't you use Qt QSS for this? It working just fine. Have a look here : http://www.qtcentre.org/threads/42211-QTableWidget-alternating-background-color?p=263046#post263046

myTable->setAlternatingRowColors(true);
myTable->setStyleSheet("alternate-background-color: yellow;background-color: red;");

Solution 2

You could reimplement data() method of your model like this:

QVariant MyModel::data(const QModelIndex& index, int role) const
{
    if(role == Qt::BackgroundColorRole)
        return color;
    ...
}

It should be possible to do the same with a delegate using setModelData().

I ended up using a QTreeView / QTreeWidget instead. It's easy making them behave like tables. However, obviously a QTable* and a QTree* should behave in the same way in regards to filling out empty rows with alternating colors, but...

Should. In my case it works. You can try it will not take much time.

alternating color is simple, but making the alternating color fill the entire rows when the data is not enough, is different matter
