| | | | | | | | | | | | | | | | | | | | | | | * Add some icons for Light and Dark themes.

As a drive-by fix, make sure that the cursor is always at the end of QTextEdit before showing a new message. The user can change the cursor position by clicking/selecting the text, and this could previously lead to some bugs in message visualization.

* LowEnergyScanner example: migrate to QML Permission APIIvan Solovev2023-06-233-29/+46
| | | | | | | | | | | | | | | | | Update the example to use QML Permission API. This is not strictly necessary, because the example provides custom C++ wrappers around Qt Bluetooth classes, and the permission request was already conveniently implemented there. However, this example is a good candidate to show QML Permission API usage with Qt Bluetooth. That's the reason for the code update, as well as a documentation improvement.

| | | | | | | | | | | | | | | | The '\meta category' command was used for tagging examples with a specific category, used in Qt Creators Welcome mode. As we want to also generate lists of examples belonging to a category elsewhere in the documentation, replace the command with a macro that expands to the original \meta command and also adds the example to a group using the \ingroup command. This way, the category names can be used as arguments to the \generatelist or \annotatedlist commands.

* Fix .plist when building an example for iOS with CMakeJuha Vuolle2023-03-3011-137/+90
| | | | | | | | | | | | | | | | | | | | When building an example for iOS with qmake (qt-cmake -GXcode) the local Info.plists of three of the examples don't work, because they were using qmake substitutions (${EXECUTABLE_NAME} instead of ${MACOSX_BUNDLE_EXECUTABLE_NAME}), which resulted in "CFBundleExecutable is not specified". Instead use shared plist files, each for CMake and qmake. One of the removed files contained NSBluetoothPeripheralUsageDescription key, which I think can be discarded now; it is intended for iOS < 13, and the minimum for Qt 6 is 13.

| | | | | | | | | | | | | | | | | | | | | | | | | Adapt the QML code to modern guidelines: * properly create a QML module in CMake and qmake * use versionless imports * convert the Device class to QML_SINGLETON instead of injecting it into the root context * use QQmlApplicationEngine::loadFromModule() to start the app The last change actually requires that we use Window instead of a Rectangle for the Main.qml page. This, in turn, breaks the pre-existing Loader logic, because every time we load the Main.qml page, a new window is created. Apart from that, we get unqualified access warnings from qmllint, because loader is accessed from every QML element, while it is only defined in the Main.qml. To fix that, we introduce a new page for device scan, and convert Main.qml to use StackLayout instead of a Loader to avoid unqualified access warnings. While on it, also fix other qmllint warnings and re-format the QML files.

* Avoid multiple client sockets in pingpong bluetooth exampleJuha Vuolle2022-02-121-2/+6
| | | | | | | | | | | | This commit guards against creating multiple client sockets if multiple services are found. In addition the service scanning is stopped when a service has been found and we start connecting a bluetooth socket.

* PingPong example: let the parent QObject do the cleanupIvan Solovev2022-01-211-2/+1
| | | | | | | | | | | | The m_timer and m_serverInfo instances are created using 'this' as a parent, so we do not need to explicitly delete them in the destructor, but let the parent object deal with them. This also prevents a crash at application close.

| | | | | | | | | | | | | | The service info returned by the QBluetoothServer::listen() overload that returns it needs to be stored or otherwise it will be destroyed. The consequence was that the SDP "advertisement" didn't properly include the added pingpong service record on Windows.

* BtChat: fix crash when no adapter is foundIvan Solovev2021-11-161-2/+12
| | | | | | | | | | | | | | | | | The example was assuming that QBluetoothLocalDevice::allDevices() always returns a non-empty list. This is not true for the cases when desktop has no bluetooth adapters, as well as for WinRT implementation (it always returns empty list for now). This patch fixes the crash and provides some information messages to the console. Note that WinRT implementation has an extended warning, because it returns an empty list even if the adapter actually exists.

* macOS specific Info.plist file for Bluetooth ExamplesJuha Vuolle2021-11-1110-18/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | The default generated Info.plist is not enough as the Bluetooth examples require NSBluetoothAlwaysUsageDescription key to work. Without this patch on macOS 12 there are two possible outcomes: 1) If the example is built with qmake, the application will crash and the crash report will indicate that the key is missing 2) If the example is built with CMake, the application will not start as it tries to use iOS specific .plist file The patch uses absolute paths in the example CMakeLists.txt files to work around a Ninja bug: https://gitlab.kitware.com/cmake/cmake/-/issues/20181 Using relative paths resulted in "multiple rules generate" errors if the QtConnectivity module is built with examples. Note that the plist files are only effective if the application is started as an app bundle, ie. not if launching the contained binary directly.
