QAbstractItemView questions

[maximAL]

would it be feasible to use a view to represent some time-lines, each containing events?
eg, several time lines, each containing a few events displayed as eg. boxes on the timeline. of course, with full drag and drop support, plus defining begin/end of events by direct manipulating these boxes with the mouse.

an underlying data model would be straight - forward: on the top-level the timelines, each with one level of children for the events constisting of a begin/end time.

now, the problem of course would be mapping the event-items into the the timelines, since a simple grid wouldn't be sufficient (unless maybe the granularity would be high enough, to make the user believe there wasn't a grid - but that might become inefficient very fast).
now, i can imagine just drawing some boxes for the events...but not using widgets would make the whole resizing thing much more complex.

is this possible at all? or would a plain custom widget be the better choice?

Yes, of course.

Seems ok.

What would you use widgets for?

A plain widget? No. But using QGraphicsView is an option.

well, after all it would be nice to be able to use widgets, since the look should be similar to a QTableView (with one column, but the rows should contain the items), what could be achieved with a few basic widgets.
rendering everything myself seems like a daunting task - esp. since i've never done that in Qt

Consider using QScrollArea then. But if you'll want to use the model with it, you'll have to implement it all yourself. I don't know what exactly would you like to display, but if you are not sure you need widgets, consider not using them and going for the view with a custom delegate or no delegate at all (with a custom view).

what i want to achieve is a window maybe similar to the central or far right window in this screenshot from muse :

unfortunaltly i'm working under windows atm, so i can't really try it out now.
