[SOLVED] Qt5: Cannot set application font (OTF) from resource

nando76

Hi,
i have a problem setting an customized application font, loaded from resource file.

I added an OTF font to my resource file.

Then i try to set this font as default application font like this:

@if(-1 == QFontDatabase::addApplicationFont("qrc:/resources/Mohave.otf"))
{
qCritical() << "couldn't add application font";
}@

But somehow it does not work.

The output is:

@Unable to register font: Error Domain=com.apple.coretext Code=-1 "The operation couldn’t be completed. (com.apple.coretext error -1 - Could not register the font file 'qrc:/resources/Mohave.otf -- file://localhost/development/qtcreator-workspace/test/trunk/TEST-App/')" UserInfo=0x101f24cb0 {NSDescription=Could not register the font file 'qrc:/resources/Mohave.otf -- file://localhost/development/qtcreator-workspace/test/trunk/TEST/', CTFailedFontFileURL=qrc:/resources/Mohave.otf -- file://localhost/development/qtcreator-workspace/test/trunk/TEST/}
couldn't add application font@

I am using Mac OS but this font should be used for all devices (Android, iOS...)

Any ideas?

Greetings,
Nando

News:

Somehow without using the Qt resource file like this it works:

@if(-1 == QFontDatabase::addApplicationFont("resources/Mohave.otf"))
{
qCritical() << "couldn't add application font";
}@

I have the same problem:

@
if(QFontDatabase::addApplicationFont(":/tex-gyre-adventor.bold.otf") == -1)
qCritical << "no font loaded";
@

output:
@

I am having this issue today. I need to use some fonts in my qss. Running Qt 5.7.1.
Resource entry looks like:

<RCC>
    <qresource prefix="/resource">
        <file>fonts/SF-Pro-Display-Semibold.ttf</file>
    </qresource>
    <qresource prefix="/"/>
</RCC>

I have tried, both in main.cpp and my mainWindow.cpp:

QFontDatabase fontDB;
int wtf = fontDB.addApplicationFont("qrc:/resource/fonts/SF-Pro-Display-Semibold.ttf");
qDebug() << "WTFFONT: "+QString::number(wtf);

And variations of that like without qrc, without :/, etc. Yet every single time I see:

"WTFFONT: -1"

in the log and the call gives no information at all on why the font was not loaded. I also tried an otf version of the font rom another source. Ideas?

Hi,

First thing: addApplicationFont is a static method. Then you should remove the qrc and only use :/

Did you also try to load that font directly using the full path to it ?

By the way, what OS are you running ?
