QML drop and wheel events

[Schneidi]

Hi,

I wonder how I get the drop event handling in a QDeclarativeView to work.

I have a MainWindow with an QDeclarativeView and I set the MainWindow to acceptDrops this works fine.
But now I can't convince my QDeclarativeView to accept drop events.

@
this->qml_view = new QDeclarativeView;
this->qml_view->setAcceptDrops(true);
@

I thought that this could be the way to get this to work but I can't drop files in this view.
Any ideas what I have to do, to get this to work ?

By the way, are there any chances that I can implement mouse wheel events in an qml MouseArea ?

Thanks for help guy ; )

This isn't really possible at the moment -- "QTBUG-7369":http://bugreports.qt.nokia.com/browse/QTBUG-7369 tracks this issue. If you need the functionality in the meantime, it should be possible to implement a custom QDeclarativeItem subclass to handle this.

Ok the wheel event isn't a real problem, I implemented it in the mainWindow and synch it with the qml environment.

But a problem is still the fact that I can't drop files to the mainWindow because I have the
QDeclaritiveView as centralWidget in my main window.

How do I drop files into the QDeclarativeView ?

@

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

this->v = new QDeclarativeView;
this->setCentralWidget(v);
this->v->setSource(QUrl("qrc:/qml_source/test2.qml"));
this->v->setResizeMode(QDeclarativeView::SizeRootObjectToView);
this->v->setAcceptDrops(true);
this->setAcceptDrops(true);

}
@

Once I set the QDeclarativeView as central object, I loose the ability to drop files into mainWindow.

A mouse up/down can be used in the following code to increment/dec the text value when the cursor is over top the item. What is the best way to make the scroll wheel do the same? Note, I need this for many items on a single screen. With a QDeclarativeItem subclass, would I need to implement the below in C++?

With the "implement in mainWindow and sync with qml", would this approach work and how does it look from a high level?

I'm still climbing the QML learning curve, so so looking for a high level overview or a place to start.

Thanks,
