Basically subclass QSortFilterProxyModel and implement lessThan. Also, it would be better if you use a separate model's role to store the actual size in bytes instead of converting the displayed value. In this case, the comparison method would be something like class MySortFilterProxyModel :...
Introduction to Insertion Sort in C++ Insertion Sort is a type of sorting algorithm where the elements are sorted using a sub-list which is maintained to be sorted, for example– the lower part of the array is always sorted. As we move forward the next element needs to search its right...

Using The find_if_not Function The std::find_if_not() function is also part of the C++ Standard Template Library (STL) and is used to search for the first element in a range that does not satisfy a given condition. It is the complement of the std::find_if() function. ...
For the second one, you have more options, like "i" in options to find using case insensitive. And about the "string", you can use like ".string." (%string%), or "string.*" (string%) and ".*string) (%string) for example. You can use a regular expression as you want. Share...

When the compiler sees sort(v.begin(), v.end());, it knows what the types of v.begin() and v.end() are, so it can determine what RanIt should be. The process of determining template arguments for template parameters (by comparing the types of function arguments to function parameters...
