* Examples: fix a couple of nodiscard warnings from QFile::openGiuseppe D'Angelo2025-04-241-1/+6
| | | | | | | | | | In one case, the code simply checked for isOpen afterwards; refactor it to use QFile::open's result. In another case, a file was opened from the resource system, so add a check.

| | | | | | | | | | | | | Show the color that is dragged in, both graphically and textually. Revert to default palette for other data types. Prioritize colors over text: if an application (such as kolourpaint) offers both x-color and text, the color is probably the intention, and the text may be just a hex string for placing into a color text field.

* Improve drag-and-drop visual handling in DragWidgetPatryk Stachniak2024-12-061-9/+4
| | | | | | | | | | | | | | | | | | | Modified the mousePressEvent in DragWidget to temporarily detach the dragged QLabel from its parent using setParent(nullptr). This ensures the dragged widget remains visible and above other widgets during the drag operation. Re-parenting logic was added to restore the QLabel to its o riginal container if the drag action is not a MoveAction. This change addresses visual issues where dragged items could disappear behind overlapping widgets, enhancing user experience and maintaining consistent behavior.

* CMake: Add deployment API to our examplesAlexandru Croitor2024-03-223-27/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

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.
