QML and Qt Quick

Keep in mind that moving UI elements tend to be rather distracting. Perhaps a tool tip / popup is a better solution to your problem. Anyway here is a simple marquee @ import QtQuick 2.0 import QtQuick.Controls 1.0 Rectangle { width: 360 height: 360 Rectangle { id: marquee width: 100 height: label.height color: "white" clip: true border.color: "lightgray" anchors.centerIn: parent Label { id: label x: 2 text: "Hello I am a very long label" property int scrollLength: (label.implicitWidth - marquee.width) + 4 SequentialAnimation on x { loops: Animation.Infinite NumberAnimation { to: -label.scrollLength ; duration: 2000 ; easing.type: Easing.OutSine} PauseAnimation { duration: 1000 } NumberAnimation { to: 2 ; duration: 2000 ; easing.type: Easing.OutSine} PauseAnimation { duration: 1000 } } } } } @

the complete diagramscene example here- http://harmattan-dev.nokia.com/docs/library/html/qt4/graphicsview-diagramscene.html i tried inserting the below mentioned functions into "mainwindow.cpp" of diagramscene .. @ void MainWindow::mousePressEvent(QMouseEvent *event) { if (event->button() == Qt::LeftButton) { lastPoint = event->pos(); scribbling = true; } } void MainWindow::mouseMoveEvent(QMouseEvent *event) { if ((event->buttons() & Qt::LeftButton) && scribbling) drawLineTo(event->pos()); } void ScribbleArea::mouseReleaseEvent(QMouseEvent *event) { if (event->button() == Qt::LeftButton && scribbling) { drawLineTo(event->pos()); scribbling = false; } } void MainWindow::paintEvent(QPaintEvent *event) { QPainter painter(this); QRect dirtyRect = event->rect(); painter.drawImage(dirtyRect, image, dirtyRect); } void MainWindow::resizeEvent(QResizeEvent *event) { if (width() > image.width() || height() > image.height()) { int newWidth = qMax(width() + 128, image.width()); int newHeight = qMax(height() + 128, image.height()); resizeImage(&image, QSize(newWidth, newHeight)); update(); } QWidget::resizeEvent(event); } void MainWindow::drawLineTo(const QPoint &endPoint) { QPainter painter(&image); painter.setPen(QPen(myPenColor, myPenWidth, Qt::SolidLine, Qt::RoundCap, Qt::RoundJoin)); painter.drawLine(lastPoint, endPoint); modified = true; int rad = (myPenWidth / 2) + 2; update(QRect(lastPoint, endPoint).normalized() .adjusted(-rad, -rad, +rad, +rad)); lastPoint = endPoint; } void MainWindow::resizeImage(QImage *image, const QSize &newSize) { if (image->size() == newSize) return; QImage newImage(newSize, QImage::Format_RGB32); newImage.fill(qRgb(255, 255, 255)); QPainter painter(&newImage); painter.drawImage(QPoint(0, 0), *image); *image = newImage; }@

I don't know why are you using QGraphicsScene, so I don't know which of the alternatives to offer. To combine QtWidgets with QtQuick module, you need to take a look at "createWindowContainer":http://qt-project.org/doc/qt-5.1/qtwidgets/qwidget.html#createWindowContainer() function.

I found the issue. Because I hard-coded the height of the Flickable's child, the Text element, there was no content larger than the Flickable to scroll through.

The order of creation is not guaranteed. In cases where the asynchronous loading does not take the same time per delegate, you could see any random order happening. The difference between qmlscene and qtquick2viewer is odd though, and could be caused by QTBUG-31203. If you prefer the qmlscene like behavior, try using this as your C++ application: @ int main(int argc, char* argv[]) { QGuiApplication app(argc, argv); QQuickView v; v.setSource("main.qml"); v.show(); return app.exec(); } @

I used the second solution.

Hi Qurx, Don't you think that it could be a memory fragmentation issue ? I'll take a look to find a workaround but... you'll probably need to change your OS version. Bye

QWindow has setFlags(), see "the documentation here":http://qt-project.org/doc/qt-5.1/qtgui/qwindow.html#flags-prop

hey yudjin, thanks for that example. Yesterday I stumbled upon this one https://qt.gitorious.org/qt/qtdeclarative/source/87d0c02fab03b7d3bf2094af22465f029bcdd096:examples/quick/models/abstractitemmodel . Both examples are pretty helpful in this case.

well, I solved the issue by setting an alias property for image in ScrollView and accessing the ScrollView using the item property of Tab.

Sort of. I got around the problem by creating custom delegates that I then let handle input. So the table @ TableView { ... TableViewColumn { role: "value"; title: "Value"; delegate: selectDelegate } @ The delegate @ Component { id: selectDelegate Item { function select(model) { switch(model.definition.type) .... // this is just an enum defined in my code return aComponent } Component { id: aComponent // Something that can handle clicking and so forth } Loader { property var localModel sourceComponent: select(model[styleData.row]) Binding on localModel { when: status == Loader.Ready value: model[styleData.row] } } } @ Since I end up with a delegate of my own I get to choose explicitly how localModel maps to my controls. In my case its a property editor so I have multiple types of components to handle color, text, date, etc so you could simplify this down.

Please post additional information about the issues you are facing, specifically as described in - http://gpupowered.org/node/27

Still only launches easystroke and freezes :(.

Thanks, seems it is ok
