QML and Qt Quick

Well yes as far as I know the complete Qt scene graph is drawn with OpenGL, so the QSG files are just some interface classes for open GL in the end, to abstract open GL a little bit and reuse common stuff like line drawing etc. But if you really want to draw 1000 or even millions of the same object you should consider doing a native open GL approach if you care about the best performance, that can also be done with QQuickItem (without using any of the QSG* classes), you just need to override the "paint" method, there are some examples somewhere I think.

Thanks again for your time! I've been out of the office during the last few days. I'll take a look to your references asap. :) Cheers, F.

I got the same error too, when using a ListView inside a ListView, Any updates?

Done! Enjoy your Saturday!

The answers are in the "QML screen docs":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick-window2-screen.html#details

using TextArea item

Thanks for your reply,. I tried both of your solutions resetOpenGLState() in 5.2, and tried disabling GL_STENCIL_TEST at the end of paint, either of them did no help.

Hi, is there a reason you came up with your own property and function for the current index? The ListView already has a property currentIndex and also a function incrementCurrentIndex(), maybe you missed it check the doc it might help you. :) About the timer I have no idea it should work like that, try and add some log messages if it really is the timer or the function it calls that doesn't work. I never used the XmlListModel but to reload the data you might just reset the model (set the source to "undefined" and than the URL string again), you have to unset it or it won't trigger a change event so just remove the model first. :D There might be a cleaner way but this isn't so bad I think. Edit: I just checked the doc, XmlListModel has a reload function what about that? :)

thanks i try something like this : @ function getDistance(time1) // time1 another date which i make by gettoday() { return Math.round((gettoday()-time1)/(606024)); } function gettoday() { var nowdate = new Date(); return nowdate/1000; }@

Thanks for all that works ! ;))

Hi, You're printing that out in a signal handler for a property change signal. That means that if two.f0 is initialized before two.listt and two.width then you are seeing expected behaviour. Remember, QML is declarative, so the order of property initialization is not defined by the order it appears in the code (that would be imperative, not declarative). You should wait until the Component.onCompleted signal is emitted - at that point, all of the property initializations are guaranteed to be complete. Cheers, Chris.

Glad I could help you.

Thanks

Maybe the Items added to the Button in you main.qml are not added to the button directly but to a new Item, I am not sure how QML works if you create objects from QML files but you might create a new derived Item and that is why the other Items are not found in your loop? so you can maybe try the parent of you button? try and use the QML debugger to see the item tree or print this to the console and see for yourself: @ console.log(parent.children.length, parent.parent.children.length) @ maybe you need to also use the parent.parent.children list?

Meanwhile, I think the best I can do is simply to toggle the clip property to set it to false whilst the animation is in progress and then set true on completion. Its a bit flickery, but not bad. The "onRunningChanged:" is the crucial part, so thank you very much for all your help Xander84. @add: Transition { onRunningChanged: { list.clip = (running ? false : true); } NumberAnimation { properties: "x"; from: list.finalVrnOrigin.x; duration: 1000 } NumberAnimation { properties: "y"; from: list.finalVrnOrigin.y; duration: 1000 } NumberAnimation { properties: "opacity"; from: 0; to: 1; duration: 1000 } } addDisplaced: Transition { NumberAnimation { properties: "x,y"; duration: 1000 } } @

Hi, I woiuld suggest to read "this model view tutorial":http://qt-project.org/doc/qt-5/modelview.html it has many links to usefull information Have a close look at QFileSystemModel
