Can someone tell me how to use this type of a listbox ?
 
Hey guys, I have a question .. I think I sort of already know the answer to this but I thought I should just get it confirmed first .. I want to have a Maemo 5 Value Button (like in the first picture below), which when I press opens up a second dialog box which has 2 lists which show a bunch of numbers (similar to the second picture below, except that I want list columns, not three) .. How do I implement this second set of controls, namely lists inside a dialog box ? I think I would have to use a QMaemo5ListPickSelector, right ? Also, I read somewhere that I have to 'populate a model' before I can use this controls ... what does this mean .. ?

Sorry, I'm still a n00b :P ..

Alright I tried using a QMaemo5ListPickSelector together with a QMaemo5ValueButton, but when I click on the button, a popup dialog box does come up, but it doesnt any list ..

Here is a picture of what I mean:

This is the code I'm using to start up the above mentioned two components and to populate the lists:

Code:
    QMaemo5ValueButton *x = new QMaemo5ValueButton("Testing .. !");
    QStandardItemModel model (10,2);
    int j,k;
    for(j=0;j<=1;j++)
    {
        k=0;
        for(i=0;i<=9;i++)
        {
            QStandardItem *item = new QStandardItem(QString("%0").arg(k));
            k+=5;
            model.setItem(i,j,item);
        }
    }
    x->setValueLayout(QMaemo5ValueButton::ValueBesideText);
    QMaemo5ListPickSelector *sel = new QMaemo5ListPickSelector();
    sel->setModel(&model);

    x->setPickSelector(sel);
    hbox->addWidget(x);
I would say I'm probably populating the list incorrectly ..

Not entirely sure why that's not working, but I'd suggest using either a QAbstractListModel, or a QAbstractTableModel rather than the generic QAbstractItemModel. In fact, given your original post, I'd use the QMaemo5TimePickSelector instead of a QMaemo5ListPickSelector anyway.

Tried your code and it seems to work (numbers from 0 to 45 in 5 steps).

Why don't you use the QMaemo5TimePickSelector?
That displays exactly what you want.

Are you sure ?! You ran my code as it is on your N900 and you saw the lists ?!

Yes but that displays time related values only unfortunately :(

Ah, I see - you want something similar, but not using time values. Is it a single multi-column list you're wanting to display, or multiple independent lists? For a multi-column list, I think a QMaemo5ListPickSelector + QAbstractTableModel would work. No idea about independent lists though - presumably you'd need to subclass QMaemo5AbstractPickSelector and code all the functionality yourself. The source code for the QMaemo5TimePickSelector should offer some clues for that.
