Client cannot just obtain frames by grabbing a thread and listing
|
|
children. It should first setCurrentThread beforehand, and it is the
|
|
method that will actually fetch threads. Therefore, if this model
|
|
is submitted to plain QTreeView, it won't work at all.
|
|
|
|
Ideally, this should hold current thread and current frame numbers,
|
|
and only fetch the list of threads, and list of frames inside thread
|
|
when asked for by the view.
