QT 应用程序包在安装后看不到文字

First create a Qt Resource file and add your font into it.

Let’s assume that our font is Ubuntu’s default Ubuntu-R.ttf file, then we need to add the following into our main.cpp

QFontDatabase::addApplicationFont(“://Ubuntu-R.ttf”);
qApp->setFont(QFont(“Ubuntu”, 11, QFont::Normal, false));

You should have your fonts back.

two possible solution: [^so12179548]

1. pack with your application a font as a resource file, this way all platforms will use that font regardless the current systems default font.

2. The QFont class has a method called defaultFamily(). Using this you could manually set the default font for your whole QApplication.

An example (main method):

QApplication application(argc, argv);
QFont font;
font.setFamily(font.defaultFamily());
application.setFont(font);
...rest of your code...

i advice for you one way for your question: Where I am trying to get to is to set relative font sizes with the stylesheet and allow the user to select his base size from which the relative sizes are then derived. Is there a way to get there?

• create a one (dialog or widget) form named by Configuration. Create a your design where you will have a list of the fonts that you are giving customers.
• Also give them the opportunity to choose the size of the font.
  The good thing is that we can change the font when application is running.

It is a example, how to install the font for our application:

int id = QFontDatabase::addApplicationFont(":/SMSicons/segoeui_0.ttf");
QString family = QFontDatabase::applicationFontFamilies(id).at(0);
QFont _font(family, 8);
qApp->setFont(_font);
