Hello,

I have a problem with QListWidget that I embed in QGraphicsScene.
I try:

Code:
listWidget = new QListWidget();
QAbstractKineticScroller *scroller;
scroller = listWidget->property("kineticScroller").value<QAbstractKineticScroller *>();
scroller->setEnabled(true);
new QListWidgetItem("something", listWidget);
scene->addWidget(listWidget);
The list shows, but there are two problems:
-kinetic scrolling doesn't work (using scrollbar neither). Only using keys works.
-items are highlighted (and signals emitted) only on double press.

Any idea what may be wrong? And how this should be done?[/LIST]

by default most qt widgets have kinetic scrolling enabled by default that includes qlistwidget. this is qt4.6

you wouldnt need to implement an abstractscroller for that purpose.

what version do you use ?

@krk969, I have 4.6.2 20100128.
Yes, I know that this scrolling should be enabled by default, but it isn't. Adding scroller doesn't fix this.

There is QGraphicsView above this that handles mouse events. Maybe this interferes?

yeah not sure, as on its own listwidtget and graphicsview they support the kinetic scrolling by default.
if that embedding is interfering, will have to try it out to say anything.

there are apps using 4.6 available in extras-devel.
but thats how far it will go, they have blocked it for extras-testing as QT4.6 is still under development and so stays in extras-devel.

So, if you dont mind that risk , you can still have the fun

I'm not sure, but could this be related to your situation? http://bugreports.qt.nokia.com/browse/QTBUG-7761

Qt 4.6 won't have any effect to the built-in applications, because they're GTK+/Hildon. It also won't automatically make existing Qt applications spin between portrait and landspace or have any whizzbang animations unless the developers have made it so.

Setting:

Code:
QGraphicsView::mouseReleaseEvent(event);
event->ignore();
return;
and mousePressEvent, mouseReleaseEvent in proper mouse handlers for the context where I want the list to receive events doest fix the problem.

Have you tried to add a Dynamic Property called FingerScrollable (bool) to it?
