qt tutorial- colliding mouse : normalizeAngle

[Mue22]

http://doc.qt.io/qt-4.8/qt-graphicsview-collidingmice-example.html

in this tutorial,

what the function "normalizeAngle"??

i can find it class and that web page..

[mchinand]

It's at the beginning of mouse.cpp (see the bottom of the page you linked to). It returns the equivalent angle within the range of 0 and 2 Pi.

Hi,

Qt 4 project ported to Qt 5 ? If so, you are probably missing a QT += widgetsin your .pro file
