* Example: remove runfunction exampleDennis Oberst2023-03-096-81/+0
| | | | | | | | | | | | | | This example shows how to use QtConcurrent::run by calling a global function and printing the thread ID. As the documentation already explains the functionality very well, I don't think this example is necessary. https://doc.qt.io/qt-6/qtconcurrentrun.html Task-number: QTBUG-111165 Pick-to: 6.5 6.5.0 Change-Id: I42a718cdaabdaeeab39b933d12c67d11978c95da Reviewed-by: Ivan Solovev <ivan.solovev@qt.io>
* Example: remove map exampleDennis Oberst2023-03-096-100/+1
| | | | | | | | | | | | | This example only demonstrates the use of blockingMapped. Considering that the QtConcurrent::mapped~ functions are already included in the wordcount example, and have very similar APIs to the QtConcurrent::filter~ functions, which are included in the progressdialog example, this no longer serves a useful purpose.

* Build examples in isolated sub-builds using ExternalProjectCraig Scott2021-05-261-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Examples are intended to show how to build against an installed Qt. Building them as part of the main build means the way the Qt targets are defined and created are not representative of an end user's build. By building them as separate projects using ExternalProject, we can more closely replicate the intended audience's environment. This should allow us to catch more problems earlier. Having examples built as part of the main build also creates problems with some static builds where a tool built by the main build is needed during configure time. This happens with other repos like qtdeclarative but not (currently) with qtbase. Converting the examples in qtbase to be built using ExternalProject is intended as a demonstrator for how other repos can do similar. Until other repos are converted, they will continue to work as they did before, with examples as part of the main build for non-static builds only. The new build-externally behavior is only supported for non-prefix builds with this change. Prefix builds will continue to use the old non-external method. Support for building examples externally in prefix builds will be a separate change.

| | | | | | | | | | | | | | | | | | | | | - Remove the casting operator of QFuture<T> to T. It calls QFuture::result(), which may lead to undefined behavior if the user has moved the results from QFuture via QFuture::takeResult() before trying to do the conversion. - Disable implicit conversion of QFuture<T> to QFuture<void>, by making the constructor explicit. If the users really intend to do the conversion, they should do it explicitly. [ChangeLog][Source-Incompatible Changes][QFuture] Implicit conversions of QFuture<T> to T and to QFuture<void> have been disabled. Use QFuture::result() or QFuture::takeResult() where you need to convert QFuture<T> to T. Use the explicit QFuture<void>(const QFuture<T> &) constructor to convert QFuture<T> to QFuture<void>.

We can use this in the future to encapsulate similarplatform-specific behavior and adjustments, such as module generation onAndroid. In order for the examples to see the function in Qt5CoreMacros, three more additional fixes were required: * Do the build_repo_end() call _before_ attempting to build the examples, as we need the build_repo_end() to include QtPostProcess and complete the creation of all the target config files. Otherwise the find_package() calls in the examples see something incomplete. * Add more QT_NO_CREATE_TARGET guards * Always call find_dependency on the dependencies, regardless of the target creation mode. This way a find_package(Qt5 COMPONENTS Widgets) will still load Qt5CoreMacros.
