Qt uses it extensively. For big, complex objects like QTextEdit it's probably the least of your concerns, but they do avoid it for simple value types like QPoin

- flukus 10y agoA good chunk of these questions I'm asking are because I half remember Qt's binary compatibility guidelines from when I did an internship at Trolltech many years ago :) A similar list is here: https://community.kde.org/Policies/Binary_Compatibility_Issues_With_C%2B%2B https://community.kde.org/Policies/Binary_Compatibility_Issu... . It looks like the virtual function restrictions are what I was talking about, that's where pure additions can break compatibility.
