passing-variable-number-of-arguments-with-different-type

[AnneRanch]

I like to enhance or make life complicated - depending on your point of view.

Up front - so there is no (usual) derailing the post - I am not interested in discussing why such and such way is not recommend.

Here is my starting point - RTFM.

https://stackoverflow.com/questions/3555583/passing-variable-number-of-arguments-with-different-type-c

For those who work better with exxamples - this is what I am trying to replace

int ScanAllLocal(QTextEdit*, QListWidget*, QListWidget* );

I like to start with multiple parameter of SAME type something like

int ScanAllLocal( QListWidget*... QListWidget* );

I understand that the key is using ellipsis (....) , but obviously that is not enough.

The answer is already in that SO thread, but the short version is

template <class... Args> int ScanAllLocal(Args... args)

It doesn't matter if parameters are same or different type.

And then you'd SFINAE-out incompatible types and you're going to hate your life for even starting on that path ... sigh, it's just how life goes ... ;)

Well yeah, the entire idea is terrible, but OP explicitly said not to discuss that, so I didn't ;)
