Qt 6 will introduce a lot of changes when compared to Qt 5. To begin with, Qt 6 requires C++17 which by itself excludes some compilers which were supported by Qt 5. Other changes are related to APIs, the build system (move from qmake to cmake as Qt's internal build system) or general infrastructure changes in the CI and test setup. Given the deadline for the Qt 6.0 release at the end of 2020, it is likely that not all Qt modules will be ready for the deadline set by the 6.0 release schedule.
Ready-For-Qt6-Inclusion
The general list of Qt release criteria (e.g. string freeze, API reviews done, branching) as outlined by the general releases notes of every Qt 5 release (e.g. release wiki for Qt 5.14) shall continue to apply. However those deadlines and gate criteria are considered to be as "too late" to make the final decision for inclusion. Therefore the notion of an earlier "Ready-for-Qt6-inclusion" checkpoint is being introduced. The current time suggestion for this checkpoint is end of June 2020. A more precise timeline will be suggested later on. Stay tuned.
During this earlier checkpoint each module is assessed against the criteria set out below. It is the maintainers responsibility to ensure that the data is provided for their module on this wiki page. The received feedback is used to evaluate the readiness of each individual module and in turn the readiness of Qt 6. It may also be used to define the list of Qt modules which are on track and may constitute a sufficiently large but nevertheless reduced set of Qt modules ready for Qt 6.0. If the set is deemed too small other considerations such as a delayed release schedule or feature drop may be considered.
If the release criteria are not met/stated maintainers may choose to release their module via the next minor release after 6.0 in the series.
Deadline
We want to have clarity on the list of 6.0 modules by end of June. Adding two weeks of deliberations based in the feedback implies that the 15. June 2020 is the deadline for the module data. To avoid dragging the process out due to missing information, no response implies the module is automatically not included in Qt 6.0.
Release Criteria
- Port to cmake on target for completion
- Target definition:
- Library, examples & tests have been ported
- The module is built & tested in the CI using cmake and tests pass
- Continuous Integration for Qt 6
- CI runs against qtbase/qtdeclarative SHA no older than 2 weeks
- git repo is part of regular submodule update bot runs in dev (qt5.git/.gitmodules status != ignore)
- Works with the supported platforms in CI for Qt 6.0
- Backlog trajectory
- Link to Jira stating the not completed and completed Qt 6.0 development tasks
- Reviews
- Initial review of public API done (is maintainer aware of/happy with the current state?)
- Are the API changes on track measured against the expectations
- Porting/Documentation information available
- Simple list of completed API changes which may later be used to write Qt6 migration docs
- Other open comments serving as extenuating circumstances

Qt Quick Dialogs still live in the Qt Quick Controls 1 repository, which will not be part of Qt 6. Code needs to be moved over to Qt Quick Controls 2 or into a separate repository, and ported to Qt Quick Controls 2. The Dialog in Qt Quick Controls 2 is currently very limited (a popup pane within the window, not independent top level windows, and without implementation of any content for choosing files, colors or fonts); whereas the dialogs in QtQuick.Dialogs are actual top-level windows (when possible, or popup panes otherwise) and work on any platform, with native dialogs or with QML substitute implementations. So users will not be satisfied if they are missing; they need to be ported forward eventually. Another fallback for now is Qt.labs.platform, which should not be taken out of Labs because it creates a dependency on widgets.
