qtcreator

create new project:

it will complain: “no valid kits found”

hit the “Manage” button:

if package “qt5-default” is installed, there will be an selectable entry under Qt version: “Qt 5.7.1”

if this project is version managed with git or mercurial or subversion or bazaar or clear case or gerrit or perforce or cvs (if installed):

actually a pretty nice editor with debugging function… (feels a little clumsy though or one just has no clue X-D)

Welcome to the online book of Qt5 Cadaques!

Why Qt5? Because Qt5 is awesome!

Why Cadaques?

Because one of the authors had a great holiday in this rocky coastline in the north-east of Spain.

The entire collection of chapters covering Qt5 programming, written by Juergen Bocklage-Ryannel and Johan Thelin, is available here.

(this Android App https://play.google.com/store/apps/details?id=com.koderize.Mattemonster is created with Qt5)
