Qt- Add custom font from resource

Question

I added this font to resource: BYekan.ttf
I want to use this font in my application. I've tried this :

    QFont font(":/images/font/BYekan.ttf");     nLabel->setFont(font);     nLabel->setText(tr("This is for test"));     layout->addWidget(nLabel); 

But, I guess it's not working. How to use it?

Edit: After reading this question , I've tried again :

int fontID(-1); bool fontWarningShown(false); QFile res(":/images/font/Yekan.ttf"); if (res.open(QIODevice::ReadOnly) == false) {     if (fontWarningShown == false) {         QMessageBox::warning(0, "Application", (QString)"Impossible d'ouvrir la police " + QChar(0x00AB) + " DejaVu Serif " + QChar(0x00BB) + ".");         fontWarningShown = true;     } }else {     fontID = QFontDatabase::addApplicationFontFromData(res.readAll());     if (fontID == -1 && fontWarningShown == false) {         QMessageBox::warning(0, "Application", (QString)"Impossible d'ouvrir la police " + QChar(0x00AB) + " DejaVu Serif " + QChar(0x00BB) + ".");         fontWarningShown = true;      }     else         nLabel->setFont(QFont(":/images/font/Yekan.ttf", 10)); } 

I compare this font and other font, but there isn't any different on Qt. why?

Answer 1

int id = QFontDatabase::addApplicationFont(":/fonts/monospace.ttf"); QString family = QFontDatabase::applicationFontFamilies(id).at(0); QFont monospace(family);
