Is it possible to apply a custom font to all elements in QML?

问题

Like the question says, i want to know if there is a way to apply a custom font to all elements in QML like we can easily do in HTML setting the font on the tag body. I already have the font accessible in QML with:

FontLoader { id: robotoRegular; source: "fonts/Roboto-Regular.ttf" }

But now if i do something like

ApplicationWindow {
font.family:robotoRegular.name

It doesn't seem to work, and probably isnt supposed to. Or is there a way?

Im using Qt 5.11.2, QtQuick 2.2

回答1:

Try this code:

#include <QFontDatabase>

void InstallDefaultFont()
{
    qint32 fontId = QFontDatabase::addApplicationFont(":/font.otf");
    QStringList fontList = QFontDatabase::applicationFontFamilies(fontId);

    QString family = fontList.at(0);
    QGuiApplication::setFont(QFont(family));
}

This will setup the default font for QML and Widgets as well.
