QML and Qt Quick

I found answer on stackoverflow: "Columns get a bit funny with items that don't declare their width and height" from funkybro. @Column { id:screenImage Image { id: backImage width: screenImage.width height: screenImage.height source: "image://imageprovider/backimage" } }@

That did the trick.. Very strange because I tried this before but then it didn't work.

Be patient! It's no more than 16 and a half hour after your first post. Not everyone sits in front of his/her computer all the time, the folks are spread all over the world. You should wait at least a couple of days before bumping your subject to the front again.

I've updated my reply...the js code is crucial to propagate the data to the cpp code.

Ah I see...thanks!;) that helps to address similar issues as well...but I definitely need an upgrade...(of my expertise...)

[quote author="Milnadar" date="1303892815"]How about to create new listModel for every folder, and to keep them invisible until not pressed needed item? Are there any nested folders in folders which you click on? Or just files?[/quote] Indeed in a folder there are possibly subfolders and files. :(

With this flag enable the function is called in different occasion like @ItemFlagsChange ItemFlagsHaveChanged ItemChildAddedChange ItemSceneChange ItemSceneHasChanged@ But never when my children move. I will try to connect to xChanged signal. Edit : I've found a way to make it work @QVariant Line::itemChange ( GraphicsItemChange change, const QVariant & value ) { if(change == QGraphicsItem::ItemChildAddedChange) { QGraphicsItem* item = value.value<QGraphicsItem*>(); QDeclarativeItem* item2 = dynamic_cast<QDeclarativeItem*>(item); QList<QObject*> loc_o_childrens = children(); foreach(QObject* obj,loc_o_childrens) { QDeclarativeItem* child = dynamic_cast<QDeclarativeItem*>(obj); if(child == item2) { connect(child,SIGNAL(xChanged()),this,SLOT(repaint())); connect(child,SIGNAL(yChanged()),this,SLOT(repaint())); } } } return QGraphicsItem::itemChange(change, value); }@ I really dislike this way of doing things but I can't get the ItemPositionChange.

thanks. I've put my data in a class derived from QObject.

Did you take a look at the examples in Qt Creator? There are some dedicated to animation :)

i set rotation: 3600, with duration 10000, then the image still rotating for 10 seconds Thanks again @mlong

Mayby, "QProcess":http://doc.qt.nokia.com/4.7/qprocess.html can help you out?

bq. “[solved]” before it Not at the end ... this way somebody searching in the forum could easily see it :)

You could call the setOrientation() function from your QML scene as needed. You would need to make it a slot or mark it as a Q_INVOKABLE I think. Edit: And expose the object via QDeclarativeContext::setContextProperty.

SOLVED:) thanks both!!!

Thanks for reporting back with your solution! It was a nice read, and I'm sure someone will benefit from it in the future.

It seems that it works ... I have to check if it works with my C++ model for Qvector3D property binding

There isn't any official, built-in way to do this from QML in Qt Quick 1.x. It isn't especially elegant, but as minimoog77 suggested, a workaround is to use Loader or dynamic item creation to try and load a file with the needed import, and then check whether or not you've received any errors. Hopefully we'll have a better solution for this in a future version of QML.

I think you've meant @ Rectangle { property int counter: model.counter width: counter * 10 } @ Do you change qml property or property of model from c++? If second, then you should use alias instead of full qml property. And don't forget about emitting signal on property change (one mentioned in NOTIFY). P.S. And please, don't forget to highlight your code

Also, this seems to grow in memory usage by about 50-100MB/s, which is insane. Is this just not being used by anyone? Just not on a mac? I used the latest released qt-mobility compiled from scratch, if that's helpful.
