Qt Creator 3 is a Cross-Platform Qt IDE. The goal of Qt Creator is to provide a cross-platform, complete Integrated Development Environment (IDE) to develop Qt projects. NOTES: 1 - This package conflicts with qt-creator (version 2): install only one of the two. 2 - This version of Qt Creator is advised for Qt5. 3 - Before start building/editing your application, you should configure the Qt kits (both Qt4 and Qt5). 4 - QmlDesigner will work properly only if you configure the Qt5 Kit properly (Tools->Options->Build & Run->Kits) and make it the Default Kit. 5 - An old IDE configuration in user home directory (.config/QtProject*) also can lead to strange behavior. 6 - Examples, Qt5 docs and tutorials are not part of this package (except for Qt Creator Docs itself). To build Qt5 with documentations and examples do as follow: EXAMPLES=yes DOCS=yes ./qt5.SlackBuild Upgrading from Qt5 5.4.* to Qt5 5.5 can lead to errors when building the Qt5 docs. So, remove Qt5 before upgrading.
