Question

Currently I have a simple setup where I maintain a list of bools corresponding to each item in my ListModel:

http://programmingexamples.net/wiki/Qt/ModelView/StringListModelCheckable

However, now what I want to do is have two such lists bools, say IsHot and IsLarge. Then I want to have a ListView that displays each string with a checkbox for one of the bools (the “Hot” view), and a separate ListView that displays each string with a checkbox for the other bool (the “Large” bool). Any hints on how to go about this?

Answer 1

Make your model a table, return the data in two different columns, the cells in these columns will be checkable.

On your list views, call QListView::setModelColumn to set the column the list view displays.

If you want to synchronise scrolling between the lists, you would then be better using a QTableView, so that rows would match up.

Edit to add more detail on returning text and check state.

To return a text and the state of a checkbox from the model you return different data for different roles from the [data] function on your model.

From the manual for Qt::ItemDataRole:

Qt::DisplayRole The key data to be rendered in the form of text. (QString)
Qt::CheckStateRole This role is used to obtain the checked state of an item. (Qt::CheckState)

Both columns in your model would return the same data (the name) for DisplayRole but different data for CheckStateRole
