Re: [Qt-qml] How to simulate mouse event

2010-12-13 Thread martin.jones 
Yes, that makes sense.  QGraphicsView uses the press event to determine which 
item will get subsequent mouse events.

Subject: RE: How to simulate mouse event

Hi Martin,

I've done some tests for the mouse event simulation and found a rule:
The mouse release event cannot be sent singly, it must be paired with a mouse 
press event and a mouse click event will be send by system automatically.
So I cannot send a single mouse release event to any object, it's right?

BR,
Kevin Wang

We handle mouse release in our tests without any problem.  Are you able to 
provide a runable example?

Hi Martin,

Thanks for your great suggestion!
The most mouse events can be simulated successfully except 
GraphicsSceneMouseRelease event.
The onReleased handler still cannot be triggered.

What's the matter?
Hope you or others can help me again, thank you!

Subject: [Qt-qml] How to simulate mouse event

Hi,

I'm a freshman on qml plug-in development.
I want to simulate key and mouse events for testing my qml script automatically.
Now, I can simulate the key event successfully by 
"item->scene()->sendEvent(item, &keyEvent);"

But it cannot work when I call "item->scene()->sendEvent(item, &mouseEvent);" 
to simulate mouse event.
I've tried another way "QApplication::sendEvent(view, &mouseEvent);", but it 
still cannot work.
The return value is always false.

My qml script is follow, it can output log when I click actual mouse key.
Rectangle {
   id: container
..

MouseArea {

   id: mouseArea

   anchors.fill: parent

   onClicked: {

   mouse.accepted  = true;

   console.log("Mouse Clicked! key: " + mouse.button + " | keys: " + 
mouse.buttons);

   }
}

Do you have any suggestion?

Log a bug.  It would be good if you could suggest where the docs are lacking - 
i.e. where you started looking when this didn't work as expected.  The 
"accepted" behavior is documented in the MouseArea signal documentation.

Which version of Qt are you using?  There have been some fixes in PathView 
which your bug may be related to.  I suggest trying the latest qt/4.7 from git. 
If you still see the problem then file a bug with an example that can be used

Re: [Qt-qml] Accessing a QAbstractItemModel in QML outside a view

2010-11-30 Thread martin.jones 
Right now if you want to access data in your model in script, you will need to 
add methods to your model to allow that.

For the specific case of showing data from the currentItem, you can expose the 
model data, e.g.

ListView {
Id: list
delegate: Text {
property variant data: model
text: name
}
}
Text { text: list.currentItem.data.name }

Martin.

Re: [Qt-qml] How to expose widget to QML

2010-11-30 Thread martin.jones 
You may be able to do this via QGraphicsProxyWidget, but as the documentation 
states: "This class is provided for convenience when bridging QWidgets and 
QGraphicsItems, it should not be used for high-performance scenarios".  If you 
are able then it is better to port the widget's functionality to 
QDeclarativeItem.

BR,
Martin.

The parent folder is easy to get, since there is a parentFolder property.  
There is no way to get a directory in the current folder, short of using the 
model in a repeater, for example.  FolderListModel is quite simple and really 
only designed to allow selecting a file from a list.  You could add a

Unfortunately there is no easy way to add setData() to QDeclarativeView.  
You'll probably have to make your own QGraphicsView subclass, since 
QDeclarativeViewPrivate is not exported.

You can create an object from a QML string using Qt.createQmlObject(string qml, 
object parent, string filepath)

Subject: [Qt-qml] C++ MyClass to detect child added/removed from QML

I'm sure the answer is simple, but I can't find it:  I want my C++ implemented 
QML object to be notified when children are added:

//FILE: MyFile.qml
import Qt 4.7
import MyCppClass 1.0

Rectangle {
  MyCppClass {
id: myCppClass
Text { text: "some text" }   // CHILD NOT DETECTED AS ADDED
  }

  Text {
text: "some other text"
parent:  myCppClass  // CHILD NOT DETECTED AS ADDED
  }
}

In both the cases above, I'm unable to find a slot/notification/virtual 
function in the C++ implementation of MyCppClass that I can use to detect these 
children that are added.

Since MyCppClass derives from QDeclarativeItem, I see that it is a 
QGraphicsObject, mulitply-derived from from both QObject and QGraphicsItem.  I 
stumbled onto "virtual QObject::childEvent(QChildEvent*)" which looked ideal 
(since QChildEvent has child add/remove info), but it's not called in either of 
the cases above.

Then, digging into the Qt docs, I see that QGraphicsObject users should *NOT* 
look to QObject for parent/children relationships, but rather, should look only 
to QGraphicsItem.  Seems reasonable.  Unfortunately, I could not find anything 
in QGraphicsItem that looked like a slot or virtual function I could override 
to receive "add/remove child" notification events (I need both).

I'm sure this is a simple answer -- what notification does QML trigger that I 
can catch on the C++ side for (re-)parenting?

Thanks!

However, this example show us only one file. I'm looking for the better way to

How can we define the number of the file automatically. Can we do that only 
with Qml or we should use both qml/c++ ?
I'm thinking about the Repeater element, ListView element or grid element, but 
we must define the number of case each time !

Re: [Qt-qml] ListView's childrenRect

2010-11-17 Thread martin.jones 
This will not work, or worse, has undefined behavior.  ListView does not 
instantiate all of its elements - only those that are needed to fill the 
visible area of the view.  If you define the view's height to be the height of 
its children, but the number of children needed depends upon the height of the 
view, you're unlikely to get what you want.  Why does it seem to work for 
XmlListModel?  Beats me.

I'd suggest doing something like:

ListView {
  height: count * 50
}

If you don't want to scroll and you don't need e.g. the currentIndex 
functionality of the ListView then I'd suggest using a Column with a Repeater.  
This is more efficient than a ListView and automatically sizes to its content 
size.

Seems like QtQuick/QML ought to have a "declarative subprocess"

anywhere?) This would allow launching of subprocesses asynchronously,
using  "declarative" statements to handle changing application state
based on the subprocess. Subprocess state changes are expressed via
high-level messages such as: BeforeProcessExit AfterProcessExit,
OnOutputLine, OnOutputJSON, OnOutputRegexp, etc.

SequentialAnimation {

Hi,

You should be able to use the Connections element to respond to signals emitted
by a Loader's item:

//main.qml
Rectangle{
   id: root
   width: 860
   height: 540
   Loader { id: loader1; source: "A.qml" }
   Loader { id: loader2; source: "B.qml" }
   Connections {
  target: loader1.item
  onAnimationFinished: pickNext()
   }
   function pickNext()
   {
   // pick nect
   }
}

Regards,
Michael

Re: [Qt-qml] emit data on a QAbstracListModel does not update the QML ListView.

2010-09-18 Thread martin.jones 
It may be a combination of this change and others.  There have been a number of 
changes to this code since the rc was released.

If you still see QTBUG-13628 I'd suggest getting the qt 4.7 branch from 
gitorious.  If you have problems after that let me know and I'll reopen it.  

Martin.

Hi Guys,

I applied the patch to Qt 4.7.0 RC1 here on my computer and it does fix
http://bugreports.qt.nokia.com/browse/QTBUG-13664 but it does not seem to fix 
the other bug that was closed namely 
http://bugreports.qt.nokia.com/browse/QTBUG-13628. I'll check again to make 
sure.

Thanks,
Bartosh

Any plans for when this fix will reach Qt? Any chance for 4.7.1?

In qt-components, we currently have 3 of those warnings and we are doing
workarounds to avoid getting more of them :-(

I think this is the same problem I was facing.

I created a suggestion in JIRA related to this behavior:
http://bugreports.qt.nokia.com/browse/QTBUG-13170

The problem is that when creating an object dynamically, the parent is
set after all properties have been initialized. So, the parent itself
does not exist at the initialization time.

Adriano

Re: [Qt-qml] "GestureArea is not a type" plugin error on Windows

2010-05-06 Thread martin.jones 
Gestures are not built by default.  Once I had Qt built, I did:

cd src\imports\gestures
nmake

And the following files were placed in imports\Qt\labs\gestures (I built both 
release and debug)

gesturesqmlplugin.dll
gesturesqmlplugin.exp
gesturesqmlplugin.lib
gesturesqmlplugind.dll
gesturesqmlplugind.exp
gesturesqmlplugind.ilk
gesturesqmlplugind.lib
gesturesqmlplugind.pdb
qmldir

The gestures example then loaded without error (though it doesn't do anything 
due to QTBUG-9849).

Hi everyone, 

I'm trying to get the gestures labs plugin to work on a Windows machine, 
but I keep getting "GestureArea is not a type" errors running the gestures
example code.

At first I got an error saying Qt.labs.gestures could not be imported, but
after I moved the binaries into the "bin" folder, the module seems to load, 
but the GestureArea type is still not recognized.

Note that when I did the same on my Linux box everything worked fine, 
but of course it was of no use as it (the box) does not have touch support.

I've compiled both Qt and the labs module as release binaries.
Is there a problem with QML plugins under Windows?



Cheers
Mathias
