Unless you use QMake and QDoc porting to Katie or even supporting it along with
|
2016-01-31 17:59:24 +02:00
|
|
|
Qt4 in the same codebase is trivial and requires only minor changes because
|
2016-07-19 07:08:23 +03:00
|
|
|
Katie is mostly source compatible with Qt 4.8.x, compatibility with releases
|
|
|
|
|
earlier than that is not a goal. Do note that using libraries that
|
2016-05-28 01:54:43 +00:00
|
|
|
are linked to Qt4 from applications linked to Katie will trigger undefined
|
2021-01-12 04:53:44 +02:00
|
|
|
behavior.
