Cannot compile vlc-qt example - syntax error about examples

[ntadej]

So, the first argument is a name for variable to use in the loop and the second is a list. So it can be rewritten as

QList<QSlider*> list = findChildren<QSlider*>();
for (int i = 0; i <  list.size(); i++) {
  list[i]
}

This is c++11 standard. Qt 5.7 and later will require it by default. I think Visual Studio 2012 may be required.

Or, you can always rewrite the loop in older syntax.

Tadej,

Thank you for pointing this out. It looks like I need to learn more about C++11. In the mean time I am stuck with the Visual Studio 2010 compiler. Could you tell me what that line would look like using the older syntax like for(x=0; x <MAX; x++)

The statement below is more complex than my simple example above.

for (QSlider *slider : findChildren<QSlider*>()) {

Your response will help me understand how the newer range based loops work.

Thank You,

Joe Hellesen
