QML and Qt Quick

Don't you need to add port to the rtsp source ?

second, that database name doesn't look correct. the only db driver that needs file path is sqlite. third, no user name.

What have you tried and doesn't work? We need more information. 'Doesn't work' is not helpful. If you have read the article, right at the end he showed a generic class extending QSqlQueryModel that is usable from QML. I tested it against Qt 5.2, and yes it does work. Granted, with little work as QAbstractItemModel::setRoleNames was deprecated, you have to reimplement QAbstractItemModel::roleNames instead, but that is 1 minute work.

Hi, They don't but Qt is big and the developer teams have only so many members. However, you can help getting the bug fixed by voting for it and make it known that it's still an issue in the latest version.

Then you should first get yourself familiar with c++ and Qt before rushing the port. Start by a small simple function and don't forget to add tests to ensure your code is working properly. On a side note, it's Qt, QT stands for Apple QuickTime

Thanks for your reply, going to try it :)

Nobody some hint? Can someone ackknowledge that TextInput in QQuickWidget QT5.3.0 RC is working?

Thanks. That's all very interesting, appreciate the info.

Hi, I looked into it but I could not really figure out how the animations are managed. Maybe anohter strategy would be to aim ata lower level in QT. Is there a way to set the maximum rendering frame rate? Which reduce the computation ressource?

Seems that the issues are fixed in qt 5.3 alpha/beta

Thank you I will take a look and try to figure it out. Thank you again.

I should also note that the window itself does show, and any components (such as a text area) I put in it will show as well, just not the menu bar. In case it makes a difference I'm on Ubuntu 14.04

Hi, Qt does not offer advanced mathematical functions. You have 3 options (from simplest to hardest): Interpolate your data in MATLAB before passing it to Qt Link your Qt project to a mathematical library like "GSL":http://www.gnu.org/software/gsl/ "Write your own interpolation functions":http://books.google.com/books?id=gwijz-OyIYEC&pg=PA36&dq=interpolation

That's exactly what I was looking for. I still don't understand why the binding is lost, but I'm really after the correct way of coding QML and using an alias is much simpler than what I was doing. In fact in my actual code I will create an alias to each top level item (i.e TextField and similar objects) and that way the user of the component can have access to anything they want. Thank you very much.

Yes. use Qt.Include() see "this":http://qt-project.org/doc/qt-5/qtqml-javascript-imports.html#including-a-javascript-resource-from-another-javascript-resource

[quote author="sierdzio" date="1400221623"]Change the source of the image, not the object. Or use a Loader.[/quote] Well, yesterday I tried something like that (not with an Image), but it gave me an error saying that I couldn't modify read-only properties; I figured since the front/back were write-only, they're children properties were read-only. Now I just tried changing the source of the Image and it worked just fine. I don't know what I was doing wrong yesterday. But the Image was just an example. What I really need is a way to change insert a view created and istantiated from C++ into the front/back properties. I was messing with the the Loader a few moments ago, and it might look the thing I need, except that I can't load the new view created from C++ with that because the component is actually instantiated in the C++ side...

GOT IT. this worked: @ onClicked: { var component = Qt.createComponent("master_item.qml"); if (component.status == Component.Ready) { var tab = tabview.addTab("tab " + (tabview.count + 1), component); if (tab.status == Loader.Ready) { tab.item.obj = products.get("CR2001W"); } else { tab.loaded.connect(function() { console.log("this will be executed when corresponding tab is on focus"); if (tab.status == Loader.Ready) { tab.item.obj = products.get("CR2001W"); } }); } } } @ by extension, I should be putting callbacks on component.statusChanged as well... this gets ugly pretty fast. Refactor this on different JS file? how about my Products factory object? will it be available from js? Can I even put imports in plain js?
