They're also known as "connect by name", a +very old and unpopular feature which shouldn't be used anymore. See http://doc.qt.io/qt-5/qobject.html#auto-connection for more information about them. + +These types of connections are very brittle, as a simple object rename would break your code. +In Qt 5 the PMF connect syntax is recommended as it catches errors at compile time. + +This check simply warns for any slot named like on_*_*, because even if you're not using .ui files +this naming is misleading and not good for readability, as the reader would think you're using auto-connection. |
