Description
I have used Process Monitor to trace access to Registry.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
Qt makes substitution to "MS Shell Dlg 2" already somewhere inside
for all "non-standard fonts" i.e. not Arial, Times New Roman etc
and tries to find substitution for "MS Shell Dlg 2".
For standard fonts it does everything right.
For example I want to ask for "Arial Greek" and expect to get "Arial".
Code
#include <QGuiApplication>
#include <QFontInfo>
#include <QDebug>
QString family(QString name) {
auto font = QFont(name);
font.setStyleHint(QFont::System);
QFontInfo info(font);
return info.family();
}
int main(int argc, char *argv[])
{
QGuiApplication a(argc, argv);
qDebug() << family("Helv");
qDebug() << family("Unknown");
qDebug() << family("Arial");
qDebug() << family("Arial Greek");
qDebug() << family("Arial Undefined");
qDebug() << family("Times New Roman");
return 0;
}
Output:
19:03:59: Starting C:\report\font_sub\debug\font_sub.exe ... "MS Shell Dlg 2" "MS Shell Dlg 2" "Arial" "MS Shell Dlg 2" "MS Shell Dlg 2" "Times New Roman" 19:03:59: C:/report/font_sub/debug/font_sub.exe exited with code 0
