is there a class in the Qt framework to use an unlock pattern?
I want to use it as an alternative for entering a password. This would be much easier for devices without a keyboard.
AFAIK, there's nothing ready made for that. Maybe KDE's Plasma has something like that.
Out of curiosity, what kind of device are you targeting ?
Do you need a QWidget or QtQuick component?
Just a PC with a touchscreen without keyboard and mouse.
