6 \title Changes to Qt D-Bus
7 \ingroup changes-qt-5-to-6
8 \brief Minimal porting effort to be able to switch to Qt 6.
9
10 Qt 6 is a result of the conscious effort to make the framework more
11 efficient and easy to use.
12
13 We try to maintain binary and source compatibility for all the public
14 APIs in each release. But some changes were inevitable in an effort to
15 make Qt a better framework.
16
17 In this topic we summarize those changes in Qt DBus, and provide
18 guidance to handle them.
19
20 \section1 API changes
21
22 The QtDBus module has undergone some basic consolidation and
23 cleanup. There should be minimal porting effort to be able to switch to Qt6.
24
25 \section2 The QDBusMessage class
26 The QDBusMessage::call() and QDBusMessage::asyncCall() methods with a fixed
27 size of arguments have been removed in Qt6.
28
29 \section2 The QDBusArgument class
30 The QDBusArgument::operator<<() specializations for QHash, QMap and QList
31 have been unified into common specializations for associative containers.
32
33 \section2 The QDBusConnection class
34 The QDBusConnection::sender() function has been removed in Qt6.
35
36 \section2 The QDBusMessage class
37 The QDBusMessage::createErrorReply() function now takes the QString \c name
38 argument by const reference instead of taking by value.
39
40 \section2 The QDBusPendingReply class
41 QDBusPendingReply has been changed to be a variadic template class in order
42 to support more than 8 template parameters now. The template parameters
43 are the types that will be used to extract the contents of the reply's data.
