QML and Qt Quick

[quote author="Zlatomir" date="1405190039"]You need to cast the pointer to the correct type, recommended ways are: dynamic_cast or (because you have a QObject) "qobject_cast":http://qt-project.org/doc/qt-5/qobject.html#qobject_cast: @ Champions* item2 = qobject_cast<Champions*>(datalist.at(2)); if(item2) item2->name(); @ [/quote] Thanks a lot ! It works well for me !

i think it is possible with CSS, but i don't know the way.. btw, thanks

switching to pointSize do not help, the same problem !https://lh3.googleusercontent.com/-bv71O37AKeo/U8Iwagd8XJI/AAAAAAAAG_Q/wdfXHMnbnBg/w549-h878-no/Screenshot_2014-06-27-18-20-56.png(qml problem)!

Point sizes are device-independent. A 16pt font should theoretically be the same size no matter what device you're on or what the density of the screen is, assuming that the vendor of the display follows "VESA standards":http://en.wikipedia.org/wiki/Extended_display_identification_data. You can use JavaScript expressions in QML to achieve a percent value. For example: @font.pixelSize: parent.width * 0.9@ That's 90% of the parent.width. Figure out what you want 90% of, then multiply by 0.9. ;)

Here's the full answer to the question. Inside your QObject derived subclass, you can do the following: @ // get rootContext() and required contextProperty as QVariant QVariant myobject_v = qmlEngine(this)->rootContext()->contextProperty("myname"); // cast QVariant first to QObject* and then to my desired ObjectClass* ObjectClass myobject = qobject_cast<ObjectClass>(qvariant_cast<QObject*>(myobject_v)); @ http://stackoverflow.com/a/3918893/532513 showed how to cast from QVariant to ObjectClass*, the rest was found through snippets of documentation scattered all over the place. :|

[quote author="flobe" date="1405152382"]Well, I'm looking for a reusable toggle button component which state (on or off) can be controlled by a mouse click (which results in - as far as I see - a Javascript assignment) as well as from a state property of another QML item. ... I have just checked the CheckBox implementation of QtQuick.Controls which show the same problem. It is not possible to keep two CheckBox items in sync by using property bindings.[/quote]I think that makes sense. A CheckBox and ToggleButton have a boolean property. Usually, the mouse controls that property. If you bind that property to an external boolean variable, then the external variable will also try to control that property. You now have two different and unsynchronized things trying to write to that property -- this can create conflicts, as you've discovered. I think your onStatusChanged solution is the only way to achieve what you want.

To pass component, pass pointer to QQmlComponent inside fromValue(), as follows... @ QObject* m_pTabView = findChild<QQuickItem >("myTabView"); if (m_pTabView) { QVariant returnedValue; QVariant title = "Hello"; QQmlComponent component = new QQmlComponent(&app.qmlEngine(), QUrl("qrc:/qml/Measurements.qml"), this); QMetaObject::invokeMethod(m_pTabView, "addTab", Q_RETURN_ARG(QVariant, returnedValue), Q_ARG(QVariant, title), Q_ARG(QVariant, QVariant::fromValue(component))); } @

That's great. It was a good effort from you. You can mark the thread as solved by editing the thread title and prepend [solved] so that other's may know that this thread has a possible solution.

you can try importing like import "../../../../utils1.js" if qml and js are in drive.

Hi, Yes that's possible. Check "headerDelegate":http://qt-project.org/doc/qt-5/qml-qtquick-controls-tableview.html#headerDelegate-prop. You will need to create a Button Component and assign to it.

Hi, I came across pathview..i am trying to get output...will update soon wen completed

Also another observation, keeping ApplicationWindow if you set the z value of Rect to negative also works as expected.

That is all really cool, thanks for sharing!

oh. thanks.

You are very kind. thank you for your time ! :D

Hi, Just another suggestion, would PathView be suitable to you requirement ? Check "PathView":http://qt-project.org/doc/qt-5/qml-qtquick-pathview.html docs. There's "PathAttribute":http://qt-project.org/doc/qt-5/qml-qtquick-pathattribute.html object which can be used to set Opacity or Scale etc.. Once used the corresponding properties are set properly as per the Item's position in the List. Check the example in it's description. With PathView you can simulate a Simple ListView or other Complex paths by setting the proper Path like PathQuad, PathLine etc..

[quote author="andreyc" date="1404932898"]Thank you for the sample project. I tried to build it and got the errors: @ WARNING: Failure to find: qml.qrc /home/achichinov/Qt5.3.1/5.3/gcc_64/bin/rcc: File does not exist 'qml.qrc' @ Do I need to create it or you missed it in your submit?[/quote] Thanks. I forgot that it doesn't add those by default. I've added it to source control and it's out there now.
