* Examples: Disable QtC junction points for examples using 'shared' directoryKai Köhne2024-11-265-0/+105
| | | | | | | | | | | | | | | To work around path length limiations, Qt Creator optionally uses junction points to shorten the build directories. This however breaks examples that require sources outside their 'root' directory. QUIP 13 states that examples should be self-contained. Anyhow, fixing this is a larger effort, so for now just disable junction points in Qt Creator for these examples.

* CMake: Add deployment API to our examplesAlexandru Croitor2024-03-229-81/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Projects were modified using the tool at: https://git.qt.io/alcroito/cmake_refactor A couple of examples had to be adapted manually, due to them including more than one app per example subdirectory. The INSTALL_EXAMPLESDIR and INSTALL_EXAMPLEDIR assignments were removed. The install(TARGETS) calls were modified according to our documentation snippets for qt_generate_deploy_app_script. A qt_generate_deploy_app_script call was added for each executable target. Note that the deployment step will be skipped in the CI for now, because we enable QT_DEPLOY_MINIMAL_EXAMPLES and thus QT_INTERNAL_SKIP_DEPLOYMENT, and also because standalone examples are not enabled yet, and deployment is disabled for in-tree (so no-standalone-example) prefix builds. The install(TARGETS) calls for each example will still run, installing the examples into an installed_examples directory, that will not be archived by the CI.

* Examples: fix touch handling in painting examplesVolker Hilsheimer2023-12-151-3/+6
| | | | | | | | | | | | | | | | | | | | On macOS, we don't deliver a press event for the first press on the track pad (Qt::WA_TouchPadAcceptSingleTouchEvents is not set by default, so Qt doesn't deliver a single-press on the track pad as a touch event - that makes some sense or at least maintains compatibility). Because of that, point 0 is never added to the finger-mapping hash. When point 0 is then released, we didn't check if we found a valid iterator for that point ID, and the example crashed. Fix this by checking that we have a valid iterator before dereferencing, and by handling Stationary events in the same way as pressed (add the point to the mapping if it's not already there).

* QObject: optimize the common case of findChildren(QString())Marc Mutz2021-07-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Outside tests, all in-tree callers of QObject::findChildren() pass no name to match, and in my experience that is also true for the vast majority of out-of-tree users. Avoid the temporary QString creation in the caller and the repeated QString::isNull() checks in the implementation by overloading findChildren() without a name argument and checking for name.isNull() only once, forking off into separate helper functions. Adjust in-tree callers that used an explicit `QString()` argument in order to pass options, which goes to show that `name` should never have been the first argument of findChilden() in the first place, even though I appreciate the symmetry with findChild() (the use-cases of which, however, are radically different). Change a `findChildren().size() == 0` call found while scanning for findChildren() calls to `!findChild()` as a drive-by. Modernize loops in the various qt_qFindChild{,ren}_helper() overloads to match how the new code looks. [ChangeLog][QtCore][QObject] Added findChildren() overload taking no name (thus optimizing this common case).

* Build examples in isolated sub-builds using ExternalProjectCraig Scott2021-05-261-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The examples use an intermediate object library to avoid duplicate file compilation. The examples worked when built as part of Qt because the shared directory was always added, and Qt::OpenGL is available implicitly. Change each project to add_subdirectory(../shared) if the object library is not available, thus making the examples build as standalone projects. Call find_package inside the shared project, to ensure the Qt packages are found. Create an alias called 'painting_shared::painting_shared' and link against that to ensure that any failure is caught at configure time rather than build time. Adapt the pathstroke example to use the object library. Comment out the code for the OpenGL scopes, because it's handled by the object library. Make sure the OpenGL dependency is public.
