int main(int argc, char *argv[])

Hello this is my main.cpp of application where I want to set different themes. QFile data("/home/einfochips/BEL_VMS_CLIENT/stylesheet.qss"); This line reads stylesheet file and applies once I run application.
But I have another dialog with name theme.cpp where I have 3 radiobuttons which have some colors. So my question is how to apply stylesheeet to qAPP runtime?

You can apply stylesheets to individual widgets or set the call setObjectName("MyDialog") in the dialog you want to look differently and include a section on the sylesheet dedicated to it

#MyDialog{
// style for dialog
}

I want to make change to all my dialogs and mainwindow too.
