QML and Qt Quick

Thank you very much. I download Qt libraries version 4.7.3. I configure lib with: ./configure -embedded arm -xplatform qws/linux-arm-gnueabi-g++ -release -prefix /usr/local/Qt-target-full -qt-gfx-linuxfb -qt-kbd-tty -little-endian -host-little-endian -no-opengl -opensource After that i do make and make install. The resulting library has no support for qml. Why?

When you say: "no videos are shown" what exactly happens? What I'm interested in is: can you see a thumbnail or anything? Maybe you can post a picture of what you have have you tried different sizes? It could be a problem. I haven't used the Video element, so I don't know if you can resize a video... were you able to load one single video i.e. without model/delegate? Maybe the file type is not supported... Try to describe what you obtain, this way we can see better what the problem could be :)

You can create circles dynamicly with JS and position them. On odd rows circles start from x=0, x = circle.width, x = circle.width*2, .., x = circle.width * n and on even rows from x = circle.width / 2, x = circle.width + circle.width/2, ..., x = circle.width * n + circle.width/2. Also you can add spacing in calculations.

As QML is mostly for UI work, I would suggest you expose a 'CropSave' function or similar from the underlying Qt (C++) that you can then call from QML. You'd probably want a whole set of backend C++ functions if you are making a QML image editor program.

thanks , Vijay , I think it is the same , I will try that , thanks very much

@ i have same problem with you; i have some ideas: 1,create the custom listview, but i find the listview in qml can not inherit 2,set the contentX or contentY dirently after a pan event; but i find some conflicts with the nature animation if you have some advises,you can use tigriswing@gmail.com @

I even tried editing this http://projects.developer.nokia.com/QMLTemplates/wiki/WikiStart#accordionlist I need to study more I guess. :(

Thanks matrixx, You certainly know where to get good stuff! Cheers, Eddy

That;s what I was looking for!+) THANKS A LOT - SOLVED

Thanks! This is definitely what I've been looking for. :D. Edit: How do I make the listelements clickable?

I have not messed with a webcam in ages so please excuse me if this sounds ridiculous. If the webcam puts stuff in a file you could always just use the the QML Video Element from Qt Mobility to display it. It would be great to link your webcam into it through @ source: "webcam feed.avi" @ Like I said though I don't know how/if this would work. Here is the documentation on the video portion of Qt Mobility. - "QML Video Element":http://doc.qt.nokia.com/qtmobility-1.1.0-beta/qml-video.html

Or you can handle mousePositionChanged on QML side. @QmlApplicationViewer viewer; ... viewer.rootContext()->setContextProperty("mainwindow", &viewer);@ @TitleBar { id: titleBar; width: parent.width; height: 40; opacity: 0.9 MouseArea { id: mouseRegion anchors.fill: parent; property variant clickPos: "1,1" onPressed: { clickPos = Qt.point(mouse.x,mouse.y) } onPositionChanged: { var delta = Qt.point(mouse.x-clickPos.x, mouse.y-clickPos.y) mainwindow.pos = Qt.point(mainwindow.pos.x+delta.x, mainwindow.pos.y+delta.y) //console.log(mouse.x-clickPos.x,mouse.y-clickPos.y) } } }@

Can some "TROLLS" help me answer this???

Thanks Lukas for the reply. Is there render performance difference comparing the QDeclarativeView with QDeclarativeEngine? Also, i did the following but the qml rendering is still not smooth. Any other advices? anyone? @ scene->setStickyFocus(true); scene->setItemIndexMethod(QGraphicsScene::NoIndex);@

Good stuff, I've added category and ToC to it. http://developer.qt.nokia.com/wiki/diff/Qt_Quick_Image_Viewer for details

Nice wiki page, cheers :)

clip property will work it out. Look into Assistant for more info

Thank you! :).
