Hello, I sent the following email a few weeks ago but got no answer. The github statistics also show that only one person downloaded the "dummy" project I wrote to demonstrate my issue... :( With the recent announcements and the Jolla boat sailing on, I'd like to get this solved.
I'm even willing to pay if necessary. Thanks a lot, All the best, ----- Mail original ----- > > I have a model that inherits from QSqlTableModel. A SilicaListView > shows the data. This is very easy to do, thanks to Qt/QML :) > > Each list item has a ContextMenu with a "Delete" entry that allows > the user to delete the item.
