QML and Qt Quick

I'm using QtCreator 3.4.1 and still have this issue. @jalomann said: And after reading readme, I found out that installing qt5-qtdeclarative-import-models2 is the missing package. @pkcon install qt5-qtdeclarative-import-models2@ @jalomann how do I get and install this "qt5-qtdeclarative-import-models2"? I'm using Windows btw. Can you give me the link to the readme file?

Hey @Wieland, You are correct. You can see what I was talking about if instead of true you type True for the transparentBorder tag. For some reason I corrected it on the code I posted here, but not in my original code.

Hi @halil-sogut68 if you meant in Image then setting source to blank (i.e "") will remove that image.

@Khachatur That's fine. I'm glad that its working :) Happy Coding ...

I was missing import QtQuick.Extras 1.0 On android and Windows now it works fine, it does not work with winrt

@vishnu From subfolder to main folder : i do it like this import "../subfolder" But on reverse i am confused what to do. How about import "../" ?

@antemort First check if that QML contains no error. Secondly you need to findChild in the rootObject QQuickItem *rootItem = view.rootObject(); //root item in QML QQuickItem *child = parent->findChild<QQuickItem*>("childobjectname"); //find child of that root object using its objectName child->setProperty("angle1", 160); //set property angle1 to 160

@eLim You're Welcome :)

@vishnu Works on Ubuntu 14.04 with Qt 5.4.1 Edit: Works on Windows 7 64 bit with Qt 5.4.1 and MSVC 2010 too. Try searching https://bugreports.qt.io for possible bugs if any.

@p3c0 Okay.

@antemort You can put the 2 gauge images besides eachother inside a RowLayout and add it to the Image element which contains that background image. Advantage of layouts is that it automatically positions the items inside it when it resizes.

Hi SGaist, I did of curse know about importing and using simple javascript code in my qml tests. But what I was wondering was if it is possible to use the multitude of javascript libraries that are out there, mostly the impressive ones that deal with animations like the one I linked to. Thanks for the links p3c0, I believe that by studying them I may be able to port a javascript library to a qml compatible version.

Hi @Tank2005, AFAIK setting anchors wont work from C++ side. You have to either do it on QML side or you can calculate the x and y positions programmatically on C++ side and set them. The latter can be done following way: child->setProperty("x",parentItem->width()/2-child->width()/2); //calculate and set child->setProperty("y",parentItem->height()/2-child->height()/2); Edit: Since you want to fill you can use parentItem's width and height item->setProperty("width", parentItem.width); item->setProperty("height", parentItem.height);

Hi @Pheelbert, Make use of QQuickWindow::beforeRendering signal to draw the OpenGL stuff beneath QML scene. Have a look at this flow for more info, especially Pt. no. 8 and the example suggested by @SGaist.

@Leonardo Yeah, that works. Thank you.

@greenhouse , Thank you for your post, it was informative. I have made a lib using the following .pro file. TEMPLATE = lib TARGET = QMLLibrary # Input RESOURCES += qml.qrc CONFIG += qtquickcompiler #CONFIG += lib there are two QML files in qrc file. ClickButton.qml CustomButton.qml And i have .dll file QMLLibrary.dll in my release folder. Now how can i use the those qml components using the lib i generated. ?
