Although this problem is not specific to QML but my application is QML
application in which I am getting error, based on qt4.7 beta2.

Thanks Bea, that's exactly what I needed!
Yes, should be nice to see that in the reference documentation

If an enum is exposed to Qt's Meta Object system using Q_ENUMS, the enum is
automatically available to QML.
This is mentioned in
http://doc.qt.nokia.com/4.7
Edit: a work around that I just found:
=== MyScrollbar.qml ==
Rectangle {
property int orientation: undefined
property alias scrollbar: scrollbar
QtObject { // this is my "enum" :)
id: scrollbar
property int vertical: 1
property int horizontal: 2
}
[...]
}
=== app.qml ===
MyScrollb
Isn't there a way to expose an enum to QML with qRegisterType or something?
How do you guys expose enumerations to QML?
While I understand that Javascript is weakly typed and hasn't such
concept as constants, when you are developing generic components, it's
very scary to do stuff like that:

You can also use PathAttribute
(http://doc.qt.nokia.com/4.7-snapshot/qml-pathattribute.html) -- that allows
you to change the appearance of the items in the view based on their position
in the path.

Is there any way to declare enumerations in QML? For example, assume I
have a custom element called "MyText" that has a property called
sizeType, for which the possible values are: "small", "medium", or
"big."

That's much better. I totally missed ScriptAction.
I think I prefer this to your other suggestion (using
onPlaybackCompleted) since it allows me to keep all the sequencing
information in one place.
My playback function is asynchronous, but I suppose I can add a method

Makes sense. I cooked up something similar, but I don't like it at all :-)
Instead, I started creating a C++ class for sequencing these things,
but ran into a strange (?) issue.

item->setOpacity(1);

Interesting problem.
I haven't seen anything that is designed for this type of thing, perhaps the
guys in Brisbane have an idea for that.
But, I have an idea for a way to do it:
* Se up Element A onOpacityChanged to start playing sound
* Know (before hand) how long the audio clip is.

Hi there
I think you are missing a concept regarding how states work in QtQuick.
Every item has an implicit state called "". By default every item starts in
that state with the initial properties set. With that in mind, the following
makes more sense.

Thanks, Alan.
I have another question related to my example.
As you saw, I am using SequentialAnimation to sequence animations, but
what if I want a non-animation in the sequence?
For example, assume I've exposed a C++ "MediaPlayer" component to QML,
which has a playFile(path) slot and playbackC
I'm not sure if there is an easy declarative way to do that.
You could probably write a javascript function that would take care of some of
the typing, something like:
Component.onCompleted: {
for(var i = 0; i < target_id_list.count(); ++i)
{
var obj = numberAnima
Hi Alan,
Sorry for not being more clear.
I have a large number of pages, with each page containing several
elements. The "fading in" behaviour applies to the elements on a
given page.
The large number of pages is my motivation for encapsulating this
behaviour, so I don't have to re-implement it
So it's a slideshow and each element is a page, and you have hundreds of pages?
Or do you have a few pages each with a bunch of elements?
Or do you have hundreds of elements which pop in and out on a single page?
Depending on what you mean, you could try putting your elements in a model and

Hi all,
I am building an application that has a PowerPoint-like informational
component. To this end, I have a bunch of QML files that display
content progressively, with items fading in one at a time.
In my current implementation, I give each object an id and set opacity
to 0. I then have a Sequ
Bind properties of those objects to data in the model elements.
Change the date in the model elements.
That's what I ended up doing, anyway.

The following example comes from the docs for Flippable:
import Qt 4.7
Flipable {
id: flipable
width: 240
height: 240

property bool flipped: false

back: Image { source: "back.png" }

Thanks for the quick response. I modified my apache config to add a

Further investigation made clear that onFocusChange is not being
emitted when the item is inside a FocusScope. I filed a bug for that:

Hello everyone,
We are using the latest version of Qt 4.7 from the repository, and the
focus works very well, in a very intuitive way, much better than with
the old "wantsFocus".
Except for one thing: onFocusChanged never gets called.
Sure, we could use onActiveFocusChanged instead, and indeed,

This gets me thinking: it would be really nice if there were more
information on what exactly QML is doing behind the scene. What
impacts performance, and what doesn't.
What costs the most, in QML? Bindings? Javascript evaluation? Memory
allocation for items? And why? Yes, I'm aware that some of t
