Add QML objects to your C++ widget application.
My company's High Command has ordered me to develop a tumbler.
This tumbler or rrrrrrrr-thing as we call it is a QML type object. And I have no experience with QML. I have already googled some stuff but I can't find how to add a QML object to the rest of my application.
I do know:
- I have to use a QGraphicView widget. I already have one of those in use with some extra space left. (I'm using Qt 5.8)
- I must include: #include <QtQuick/QQuickView> and #include <QtQml/QQmlEngine> in the header file
- I must make a new QML file.
What I don't know:
- how can I make a QML object in my cpp file and give it a place on my QGraphicView?
Hm so far for the need of a QGraphicView :)
I have done:
- added to header.
- added to header
- added to setup of CPP file
view = new QQuickWidget; view->setSource(QUrl::fromLocalFile("Tumbler.qml")); view->show();
But I'm having error messages
mainwindow.cpp:-1: error: undefined reference to `QQuickWidget::QQuickWidget(QWidget*)' mainwindow.cpp:-1: error: undefined reference to `QQuickWidget::setSource(QUrl const&)' mainwindow.cpp:-1: error: undefined reference to `QQuickWidget::QQuickWidget(QWidget*)' mainwindow.cpp:-1: error: undefined reference to QQuickWidget::setResizeMode(QQuickWidget::ResizeMode)' :-1: error: collect2: error: ld returned 1 exit status
Did I include the wrong library or something????
BTW: I also added a QQuickWidget to the ui which is named 'view'
Did you add
QT += quickwidgets
to your pro file as is stated here http://doc.qt.io/qt-5/qquickwidget.html ?
Ok that solved the error problems. I don't think I will forget this a 3rd time @jsulm ;)
I also ditched the code I had and I moved the QML file to the resource folder. Using Qt creator's convenient style sheet bar thing (that bar in the UI on the right with all the parameters) I selected the QML file and I got me a working Tumbler \o/
I am only far removed from the part in which this tumbler is going to be but... minor detail
