Change the font of the application

[Mr Gisa]

I want to change the application font for everything. In the main file I tried to load a font using QFont and setting it to the QMainWindow with setFont and it works normally, the problem is that if I change the stylesheet of any widget in it like to set the font-weight to bold it requires me to use font-family as well in the stylesheet or it will switch to the default font automatically. If I use the setFont on the QApplication it works better than in QMainWindow, I don't have to specify the font family in the stylesheet, only setting the font-weight to bold will still use the same font, the problem is that the fonts are way bigger than normal.

How to set the font to the entire application?

Hi,

Maintain common stylesheet string for whole application keep it in common class. that string should contain font family and font width as well. wherever you want to use the stylesheet make use of that string directly so that it avoids writing the styleseet properties multiple time.

@Venkatesh-V Instead of doing that isn't it better to use stylesheets already like this?

* {
    font-family: ...
    font-size: 16px;
}

I asked about the usage of setFont because it's faster than using CSS, but well...

@Mr-Gisa
Yes, what you have written is the simplest & best way to set the overall font.

You can assume that the time taken to act on this CSS is "below negligible", so don't worry about speed versus setFont()!
