QML and Qt Quick

Hi, Have you tried using "pincharea":http://qt-project.org/doc/qt-5/qml-qtquick-pincharea.html and passing your camera obj to "pinch.target":http://qt-project.org/doc/qt-5/qml-qtquick-pincharea.html#pinch.target-prop property ? To mention I have not used it personally.

Argh, i found the problem, i did a very simple mistake: The property i want to set in the SimpleList Component has to be in the root Object, so instead of this: @ Rectangle { ListView { id: list_view property DataObject theDO ... @ It has to be done this way: @ Rectangle { property DataObject theDO ListView { id: list_view ... @ Wow, thats an easy solution for a (seemingly) complex Problem. Greetings, Nils

You've found it. StackView is the Qt5 version of PageStack.

Thanks, really helped.

Ok, it seems, that suggestion by SGaist about installing OpenSSL was a solution(since Qt Creator in Windows supports only 32-bit projects, I installed 32-bit OpenSSL version), but I would like to know the mechanics why JavaScript from imported file requires it, but QML don't. Thanks, SGaist - I'm setting it as answered, as it at least solves my problem with importing JavaScript file and solves other logical coding problems.

Haven't found any response / solution yet; reported the following bug so that I don't forget later on: https://bugreports.qt-project.org/browse/QTBUG-39758

No problem :). Please at [solved] to the title for the other readers.

That's it! Many thanks :)

Ok, I will figure something out. Thank you.

Hi everyone! Today I've tried to load new QtCreator from "master":http://download.qt-project.org/snapshots/qtcreator/master/2014-06-10_239/qt-creator-opensource-mac-x86_64-master.dmg and get the same crash after load QtCreator. The full crash log you can find "here":http://dshav.com/logs/qtcreator_crash.log. I've tried load QtCreator using Macbook Pro with Retina display and MacOS 10.10 Beta 2.

Please tell me there is a better solution than this: @ /* in GenericNew.qml */ onChildrenChanged: { for(var ii = 0; ii < children.length; ++ii) { if(children[ii].objectName.search("attr-")>=0) { console.log(children[ii]) children[ii].Layout.fillWidth = true } } } @

have Qt 5.3.0 on Mac. Does not work. 1 thing i should mention is that the documentation does not mention onActiveChanged for QML Window {} element. It is just that QWindow has it and hence available to QML as well. <1> What could be the issue/solution (or maybe there is some other way to do it) <2> Actually I am trying to make my own combobox. The DropDown is a Window {} with flag as Qt.Popup (or Qt.SplashScreen which produces less flickering when in full screen mode) which i need to close moment the user clicks anywhere outside it and hence i need to capture such a signal. Do you know of a better way to make such a drop down?

Thanks for clarifying. Another option is to use Qt.createComponent() and createObject() from javascript. The documentation for createComponent covers usage pretty well. The QML dynamic scene example provides a demonstration. As long as it works for you, I would stick with the ListView.

Works perfect, thanks :)

[quote author="jeremy_k" date="1401233474"]Based on the documentation for Canvas, I suspect you want to set canvasSize and canvasWindow, unless the display being targeted really is greater than 8520 pixels wide. For me with Qt 5.3.0 and XCB, a canvas with width or height greater than 8192 fails to render. I'm not sure where the limitation comes from, but the fact that it occurs above 8k seems noncoincidental. Does a width of 8519 work for you?[/quote] hi, thanks for your tips. I do not test such width 8519. but I guess the limitation is something to do with hardware platform, may be about the graphics chip. I port my qml code to arm platform(TI am335x, contex-A8).sadly,beyond my mind, the width can not more than 2400.

After some digging those are the two recommended ways I have found as well. Even though the hiding option apparently performs quite bad when you start to add more controls to the property window. So the loader seems to be the way to go. I did look into the QtCreator source they however seem to build up the control from text strings that are the individual components. Then they send the completed test to the Qml engine to build up all controls. Probably the most efficient way but it certainly doesn't seem to be simple or easy to maintain.

You can run QML profiler to test the speed.

Hi, You could try to do it in QML using a Canvas and http://qt-project.org/doc/qt-5/qml-qtquick-context2d.html#arc-method. I did it in C++ once and it worked out well, but the Canvas should work just as well.
