How to get the systems default sans serif monospace font?

GeraldBrandt

Hi,

Under Linux, when I create font and setFixedPitch on it, and get a nice monospaced font with no serifs. Under Windows I get Courier New. If I set styleHint() the font changes to non-fixed width.

How can I get a fixed-width (monospaced) non-serif font under Windows (actually, all platforms).

This doesn't work:

QFont font("Mono", 12);
font.setFixedPitch(true);
font.setStyleHint(QFont::SansSerif);

Hi,

You should add which version of Qt you are using on each platform.

Sorry, 5.14.1, I believe..

I just told both Linux and Windows to load the Consolas font, and it works. Linux uses Deja Vu Sans Mono instead.

@GeraldBrandt, did you ever learn how to ascertain which font aliases correlate to which fonts on Windows? If not, I've recently asked https://webmasters.stackexchange.com/q/145196/122892, but that's solely half of the puzzle, so I'd like to know if possible.

@RokeJulianLockhart You should be able to create a QFont and then use QFontInfo to see what you actually got and whether it was an exact match or not.

{
QFont font("sans serif");
QFontInfo info(font);
qDebug() << font;
qDebug() << info.exactMatch() << info.family() << info.pointSizeF();

// QFont(sans serif,12,-1,5,50,0,0,0,0,0)
// false "Noto Sans" 12
}
{
QFont font("Noto Sans");
QFontInfo info(font);
qDebug() << font;
qDebug() << info.exactMatch() << info.family() << info.pointSizeF();

//QFont(Noto Sans,12,-1,5,50,0,0,0,0,0)
//true "Noto Sans" 12 false
}

The aliases and their mappings vary from Windows version to version.
You could look at Font-name and the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes

@ChrisW67, that's brilliant. Thank you. I've found some useful corroberating information at https://superuser.com/a/1512700/904401.
