I suspect the bug is in the Qt code, because some other applications don't

I found a pretty ugly but working way to achieve what I want, but I still
have some issues.
Here is my approach:
1.) Utility class allowing to pass 'configured' font to QML
class FontProvider : public QObject
{
Q_OBJECT
Q_PROPERTY(QFont font READ font NOTIFY fontChanged)
public:
explicit FontProvider(QObject *parent = 0) : QObject(parent) {}
QFont font() const { return mFont; }
void setFont(const QFont &value) { mFont = value; }
signals:
void fontChanged();
public slots:
private:
QFont mFont;
};
2.) Configure QFont and pass to QML via 'FontProvider'
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QFont font("Verdana");
font.setStyleStrategy(QFont::NoFontMerging);
FontProvider fontProvider;
fontProvider.setFont(font);
QtQuick2ApplicationViewer viewer;
viewer.rootContext()->setContextProperty("fontProvider", &fontProvider);
viewer.setMainQmlFile(QStringLiteral("qml/FontTest/main.qml"));
viewer.showExpanded();
return app.exec();
}
3.) Use configured font in QML in the following way:
import QtQuick 2.0
Rectangle {
width: 360
height: 360
property font smallFont: fontProvider.font
property font bigFont: fontProvider.font
Column {
Text {
font: smallFont
text: qsTr("Hello World")
}
Text {
font: bigFont
text: qsTr("Hello World")
}
}
Component.onCompleted: {
smallFont.pixelSize = 10;
bigFont.pixelSize = 50;
}
}
The issue with such approach is that I need to create as many different
'pre-configured' fonts as many I need in the app.
I have only 'smallFont' and 'bigFont' in my example which is ok, but what
if I need lets say 'meduim' or 'bold' or whatever?
I tried to achieve it using the following approach:
Text {
font: bigFont
font.pixelSize: 50
font.bold: true
text: qsTr("Hello World")
}
.. but unfortunately it just fails to work with the following error:
"Property has already been assigned a value
font.pixelSize: 50"
Am I missing something?
