change font of stackwidget

[JonB]

@zhmh
I use QStackedWidget and just set application font and it works everywhere, QStackedWidget is not relevant.

[zhmh]

@JonB you set font application like my code?
I use it on test project with QStackWidget and it works but in my project doesn't work ,so what's the problem ?

[SGaist]

If you want all your widgets to use the same font, then just set it through QApplication::setFont.

[zhmh]

@SGaist I use this:

QFont newFont(":/new/prefix1/Nastaliq.ttf", 8, QFont::Bold, true);
    QApplication::setFont(newFont);

The size is set, but the font does not change

[SGaist]

QFont doesn't take a path as parameter but the family name.

Use QFontDatabase to load your custom font, build the QFont object using the correct family name and then set it on QApplication.

[zhmh]

@SGaist can you show me with code?
I used the qfontdatabase at first an doesn’t work!

[SGaist]

Then show the current code you use.

Can you check if addApplicationFont function returns -1 ?
as mentioned here

[zhmh]

@Ratzz yes I checked it before, this is

int fnt=QFontDatabase::addApplicationFont(":/new/prefix1/Nastaliq.ttf");
     qDebug()<< fnt;

returns 0 to me!

returns 0 to me

Which means the fond is loaded properly.

Use http://doc.qt.io/qt-5/qfontdatabase.html#applicationFontFamilies to get the font and set back to application.

Can you show the code ?

[zhmh]

@Ratzz

int fnt=QFontDatabase::addApplicationFont(":/new/prefix1/Nastaliq.ttf");
      qDebug() << fnt << QFontDatabase::applicationFontFamilies(fnt);

returns: 0 ("Nastaliq")

@Ratzz said in change font of stackwidget:

Can you show the code ?

this is my main.cpp:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    int fnt=QFontDatabase::addApplicationFont(":/new/prefix1/Nastaliq.ttf");
     qDebug() << fnt << QFontDatabase::applicationFontFamilies(fnt);
    QFont nastaliq("Nastaliq",20,QFont::Normal);
    w.setFont(nastaliq);
    w.show();

    return a.exec();
}

[Ratzz]

@zhmh said in change font of stackwidget:

QFont nastaliq("Nastaliq",20,QFont::Normal);

You should set the font which you got from the http://doc.qt.io/qt-5/qfontdatabase.html#applicationFontFamilies

[zhmh]

@Ratzz how ?

int fnt=QFontDatabase::addApplicationFont(":/new/prefix1/Nastaliq.ttf");
QString family = QFontDatabase::applicationFontFamilies(fnt).at(0);
 w.setFont(family);

is it true?

[Ratzz]

@zhmh said in change font of stackwidget:

is it true?

Yes. Does it work that way?

[zhmh]

@Ratzz No :(

[SGaist]

Where did you get that font from ?

[zhmh]

@SGaist font work with other program

[SGaist]

That's beside the question. If people knows where to download the font, they can test it on their system to find out what's going wrong.

@SGaist here you are: https://fonts2u.com/irannastaliq.font

@zhmh
I tried same font an QStackedWidget with QPushButton in it and seems fine for me.

    QStringList list= QFontDatabase::applicationFontFamilies(fnt);
    QFont nastaliq(list.at((0)));
    w.setFont(nastaliq);
