Drag'n'drop JVM crashes
Message 1 in thread
Hi,
jambi keeps crashing my JVM on drag and drop operations
if both mimeData and model I'm dropping it in are created in Java.
I managed to "fix" it by calling disableGarbageCollection() on mimeData I
create.
I've attached a minimal crashig example. When trying it you have to be
moving your mouse over first listView for a second or two (while dragging).
The longer the first list is, the shorter time is needed.
I've considered submitting this to rather to TT task-tracker but there's
practically nothing jambi related...
I'have also experienced strange behaviour of QColumnView. I refuses to use
aby other model then QDirModel:
QCoreApplication::postEvent: Unexpected null receiver
QAbstractItemView::setSelectionModel() failed: Trying to set a selection
model, which works on a different model than the view.
Not even QStandardItemModel is working.
I thought this has to be Qt issue, but I've found any related bug report in
TT task-tracker.
Jakub
P.S.: It seems like I'm bothering you a lot lately :) good news is that I'll
be back to Qt and/or Python soon ... :)

I have managed to reproduce the crash, and it will be fixed in the next
release. The problem is as you discovered, that the QMimeData object is
deleted by Java.
The QMimeData object is passed to c++ and the responsibility of deleting it is
Qt's, and not java's. Therefor calling disableGarbageCollection() is the
correct thing to do, as a workaround.

QColumnView displays a model in a number of QListViews, one for each hierarchy
in the tree.
you can try something like this:
QStandardItemModel model= new QStandardItemModel();
QStandardItem parentItem = model.invisibleRootItem();
for (int i = 0; i < 4; ++i) {
QStandardItem item = new QStandardItem("item " +i);
parentItem.appendRow(item);
for (int j = 0; j <= i; ++j) {
QStandardItem subItem = new QStandardItem("sub:" + i + "." +
j);
item.appendRow(subItem);
}
parentItem = item;
}

Your feedback is of great value to us, so keep it coming :-)
