[debug/qrc_fontawsome.cpp] Error 1

nanor

@Christian-Ehrlicher Thank you for reply. The directory of the otf file that I want to use is:
F:\qt codes\fontAwsome2\fontawesome-free-5.15.1-desktop\otfs
This file exists in my project folder.

Christian Ehrlicher

This is working fine for me:

main.cpp

#include <QtCore>
int main(int argc, char **argv)
{
  QCoreApplication app(argc, argv);
  if (QFile::exists(":/my.otf"))
    qDebug() << "File exists";
  else
    qDebug() << "File does not exist";
  return 0;
}

tmp.qrc:

<RCC>
  <qresource prefix="/">
    <file alias="my.otf">Font Awesome 5 Free-Regular-400.otf</file>
  </qresource>
</RCC>

Compiled with

qmake -proejct
qmake
make

The file is from https://github.com/FortAwesome/Font-Awesome/blob/master/otfs/Font Awesome 5 Free-Regular-400.otf

@Christian-Ehrlicher I downloaded the file from the link you provided and put it into my project folder. Also I wrote your suggested code and got "File exists".
Now I got no errors, but I got the following result:

The unicode I used is from here

I changed the code in the resource file as you posted:

<RCC>
  <qresource prefix="/">
    <file alias="my.otf">Font Awesome 5 Free-Regular-400.otf</file>
  </qresource>
</RCC>

Also, I updated my cpp file as your posted code:

#include "dialog.h"
#include "ui_dialog.h"
#include <QFontDatabase>
#include <QFont>
#include <QPushButton>

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);


    QFontDatabase::addApplicationFont(":/my.otf");

    QFont font;
    font.setFamily("FontAwesome");
    font.setPixelSize(32);


    QPushButton *button = new QPushButton(this);
    button->setFont(font);
    button->setText("\uf083");

}

Dialog::~Dialog()
{
    delete ui;
}

Christian Ehrlicher

I don't know what symbol is behind "\uf083" nor do I know if the font contains this symbol.

nanor

@Christian-Ehrlicher The unicode " f083" is from here. This is the unicode for camera.
The code I posted above is from here.
I am supposed to have something like this:

Christian Ehrlicher

I can't see what's going wrong here. My only idea would be that the symbol is not available but I can't test it.
If you think this is a Qt bug please open a bugreport at https://bugreports.qt.io

/edit: I did some more testing and would guess the symbol is not in the otf file - see http://prntscr.com/vbba17 - only a few icons are shown.

Christian Ehrlicher

Ok, it's in Font Awesome 5 Free-Solid-900.otf in the free part available from https://fontawesome.com/download

nanor

@Christian-Ehrlicher Thank you so much for helping. I downloaded Awesome 5 Free-Solid-900.otf from the link you provided, but stilI got the picture bellow:

I also downloaded the svg file from here, and I got the same output!

Christian Ehrlicher

It is working fine for me when I add Font Awesome 5 Free-Solid-900.otf to the resource file and load the font from there.
Don't know what you want with the svg though.

nanor

@Christian-Ehrlicher Could you please send me your code, if its possible? Thanks.

Christian Ehrlicher

@nanor I already posted my code above, simply replace the filename for the otf file.

nanor

@Christian-Ehrlicher I downloaded the fontawesome.ttf file from here and my code works fine now.
I don't know why Font Awesome 5 Free-Solid-900.otf didn't work for me, but the fontawesome used in the posted link project, works for my project.
I really thank you for you help. Your provided codes helped me a lot.
Best regards.
