Use qmlRegisterModuleImport() to register styles This patch completes the cumulative work done in previous patches. - Uses qmlRegisterModuleImport() to register styles. This has some added requirements: - Each style must now be a QML module -- that is, it must have a qmldir file. - As a result of the above, the module must be available within the QML import path in order to be found. - The various forms of accepted style names have been reduced down to one ("Material", "MyStyle", etc). See below for an explanation of why. - The following API in QQuickStyle is removed: addStylePath(), availableStyles(), path(), stylePathList(). These no longer make sense now that we reuse the existing QML import system. - Adds the tst_qquickstyleselector auto test back as "styleimports". qmlRegisterModuleImport() vs resolvedUrl() Previously we would use QQuickStyleSelector to select individual QML files based on which style was set. We'd do this once when QtQuick.Controls was first imported. With Qt 6, and the requirement that each style be a proper QML module, qmlRegisterModuleImport() was introduced. This allows us to "link" one import with another. For an example of what this looks like in practice, suppose the style was set to "MyStyle", and the fallback to "Material". The "QtQuick.Controls" import will be linked to "MyStyle", "MyStyle" to "QtQuick.Controls.Material", and as a final fallback (for controls like Action which only the Default style implements), "QtQuick.Controls.Material" to "QtQuick.Controls.Default". This is the same behavior as in Qt 5 (see qquickstyleselector.cpp): // 1) requested style (e.g. "MyStyle", included in d->selectors) // 2) fallback style (e.g. "Material", included in d->selectors) // 3) default style (empty selector, not in d->selectors) This is a necessary step to enable compilation of QML to C++. Reducing the set of accepted style names The problem In QtQuickControls2Plugin() we need to call QQuickStylePrivate::init(baseUrl()) in order to detect if the style is a custom style in QQuickStyleSpec::resolve() (by checking if the style path starts with the base URL). In Qt 5, init() is called in QtQuickControls2Plugin::registerTypes(), but in Qt 6 that's too late, because we need to call qmlRegisterModuleImport() in the constructor. qmlRegisterModuleImport() itself requires the style to have already been set in order to create the correct import URI ("QtQuick.Controls.X" for built-in styles, "MyCustomStyle" for custom styles). The solution By reducing the valid forms for style names down to one: ./myapp -style MyStyle we solve the problem of needing baseUrl() to determine if the style is a custom style or not, but needing to call it too early (since we now call qmlRegisterModuleImport() in QtQuickControls2Plugin(), which itself requires the style to have already been set). baseUrl() can't have been set before the constructor is finished. All of the various forms for _setting_ a style are still valid; environment variables, qtquickcontrols2.conf, etc. [ChangeLog][Important Behavior Changes] Custom styles must now have a qmldir that lists the files that the style implements. For example, for a style that only implements Button: --- module MyStyle Button 1.0 Button.qml --- In addition, there is now only one valid, case-sensitive form for style names: "Material", "MyStyle", etc. These changes are done to help enable the compilation of QML code to C++, as well as improve tooling capabilities. [ChangeLog][Important Behavior Changes] The following API was removed: - QQuickStyle::addStylePath() - QQuickStyle::availableStyles() - QQuickStyle::path() - QQuickStyle::stylePathList() - QT_QUICK_CONTROLS_STYLE_PATH This API is no longer necessary and/or able to be provided now that styles are treated as regular QML modules.

Don't delete items we didn't create Up until this patch, we've always deleted "old" items when a new one is assigned. For example, the style's implementation of contentItem will be destroyed here as it is not accessible by the user and is no longer used: Button { contentItem: Item { /* ... */ } } This was especially important before the introduction of deferred execution, as the "default" items would always be created, regardless of whether the user had overridden it with one of their own items. By deleting the old items, we free unused resources that would otherwise persist until application shutdown (calling gc() does not result in the items being garbage-collected, from my testing). Although this has largely worked without issues, deleting objects that weren't created by us in C++ is not supported. User-assigned items can be created in QML (with JavaScriptOwnership) or C++ (with CppOwnership), and it is up to the user and/or the QML engine to manage the lifetime of these items. After the introduction of deferred execution, it became possible to skip creation of the default items altogether, meaning that there was nothing to delete when assigning a new, user-specified item. This requires that no ids are used in these items, as doing so prevents deferred execution. Assuming that users avoid using ids in their items, there should be no unused items that live unnecessarily until application shutdown. The remaining cases where items do not get destroyed when they should result from the following: - Imperative assignments (e.g. assigning an item to a Button's contentItem in Component.onCompleted). We already encourage declarative bindings rather than imperative assignments. - Using ids in items. Given that these are use cases that we will advise against in the documentation, it's an acceptable compromise. [ChangeLog][Important Behavior Changes] Old delegate items (background, contentItem, etc.) are no longer destroyed, as they are technically owned by user code. Instead, they are hidden, unparented from the control (QQuickItem parent, not QObject), and Accessible.ignored is set to true. This prevents them from being unintentionally visible and interfering with the accessibility tree when a new delegate item is set.

Warn users when they customize native styles Since Qt 6, the default style is no longer the Basic style, but instead depends on the platform the application is run on. In addition, the introduction of the native styles (which are not designed to be customized) means that users customizing controls can run into visual issues and not understand why. This patch partially addresses this issue by warning when a native control is customized (i.e. a delegate is overridden): "qrc:/main.qml:11:22: QML QQuickItem: The current style does not support customization of this control (property: "contentItem" item: QQuickItem(0x1637375d210, parent=0x0, geometry=0,0 0x0)). Please customize a non-native style (such as Basic, Fusion, Material, etc). For more information, see: https://doc.qt.io/qt-6/qtquickcontrols2-customize.html#customization-reference" Ideally we'd also have qmllint integration in Creator so that users get warnings from the IDE as they code, but that's not there yet. The patch also updates the documentation by removing the code snippet from the note and referring users to the existing "Using Styles in Qt Quick Controls" section, which covers the topic in greater detail. The snippet itself is also not considered a part of the note, so the (online) styling looked a bit off. [ChangeLog][Important Behavior Changes] Customization of native styles will now result in warnings. Non-native styles (such as Basic) should be used for customization purposes, or a custom style. If you are aware of the risks and still want to customize these controls, you can ignore the warnings by setting QT_QUICK_CONTROLS_IGNORE_CUSTOMIZATION_WARNINGS to 1.

// test that the built-in styles don't have undesired IDs in their delegates
Use qmlRegisterModuleImport() to register styles This patch completes the cumulative work done in previous patches. - Uses qmlRegisterModuleImport() to register styles. This has some added requirements: - Each style must now be a QML module -- that is, it must have a qmldir file. - As a result of the above, the module must be available within the QML import path in order to be found. - The various forms of accepted style names have been reduced down to one ("Material", "MyStyle", etc). See below for an explanation of why. - The following API in QQuickStyle is removed: addStylePath(), availableStyles(), path(), stylePathList(). These no longer make sense now that we reuse the existing QML import system. - Adds the tst_qquickstyleselector auto test back as "styleimports". qmlRegisterModuleImport() vs resolvedUrl() Previously we would use QQuickStyleSelector to select individual QML files based on which style was set. We'd do this once when QtQuick.Controls was first imported. With Qt 6, and the requirement that each style be a proper QML module, qmlRegisterModuleImport() was introduced. This allows us to "link" one import with another. For an example of what this looks like in practice, suppose the style was set to "MyStyle", and the fallback to "Material". The "QtQuick.Controls" import will be linked to "MyStyle", "MyStyle" to "QtQuick.Controls.Material", and as a final fallback (for controls like Action which only the Default style implements), "QtQuick.Controls.Material" to "QtQuick.Controls.Default". This is the same behavior as in Qt 5 (see qquickstyleselector.cpp): // 1) requested style (e.g. "MyStyle", included in d->selectors) // 2) fallback style (e.g. "Material", included in d->selectors) // 3) default style (empty selector, not in d->selectors) This is a necessary step to enable compilation of QML to C++. Reducing the set of accepted style names The problem In QtQuickControls2Plugin() we need to call QQuickStylePrivate::init(baseUrl()) in order to detect if the style is a custom style in QQuickStyleSpec::resolve() (by checking if the style path starts with the base URL). In Qt 5, init() is called in QtQuickControls2Plugin::registerTypes(), but in Qt 6 that's too late, because we need to call qmlRegisterModuleImport() in the constructor. qmlRegisterModuleImport() itself requires the style to have already been set in order to create the correct import URI ("QtQuick.Controls.X" for built-in styles, "MyCustomStyle" for custom styles). The solution By reducing the valid forms for style names down to one: ./myapp -style MyStyle we solve the problem of needing baseUrl() to determine if the style is a custom style or not, but needing to call it too early (since we now call qmlRegisterModuleImport() in QtQuickControls2Plugin(), which itself requires the style to have already been set). baseUrl() can't have been set before the constructor is finished. All of the various forms for _setting_ a style are still valid; environment variables, qtquickcontrols2.conf, etc. [ChangeLog][Important Behavior Changes] Custom styles must now have a qmldir that lists the files that the style implements. For example, for a style that only implements Button: --- module MyStyle Button 1.0 Button.qml --- In addition, there is now only one valid, case-sensitive form for style names: "Material", "MyStyle", etc. These changes are done to help enable the compilation of QML code to C++, as well as improve tooling capabilities. [ChangeLog][Important Behavior Changes] The following API was removed: - QQuickStyle::addStylePath() - QQuickStyle::availableStyles() - QQuickStyle::path() - QQuickStyle::stylePathList() - QT_QUICK_CONTROLS_STYLE_PATH This API is no longer necessary and/or able to be provided now that styles are treated as regular QML modules.

Don't delete items we didn't create Up until this patch, we've always deleted "old" items when a new one is assigned. For example, the style's implementation of contentItem will be destroyed here as it is not accessible by the user and is no longer used: Button { contentItem: Item { /* ... */ } } This was especially important before the introduction of deferred execution, as the "default" items would always be created, regardless of whether the user had overridden it with one of their own items. By deleting the old items, we free unused resources that would otherwise persist until application shutdown (calling gc() does not result in the items being garbage-collected, from my testing). Although this has largely worked without issues, deleting objects that weren't created by us in C++ is not supported. User-assigned items can be created in QML (with JavaScriptOwnership) or C++ (with CppOwnership), and it is up to the user and/or the QML engine to manage the lifetime of these items. After the introduction of deferred execution, it became possible to skip creation of the default items altogether, meaning that there was nothing to delete when assigning a new, user-specified item. This requires that no ids are used in these items, as doing so prevents deferred execution. Assuming that users avoid using ids in their items, there should be no unused items that live unnecessarily until application shutdown. The remaining cases where items do not get destroyed when they should result from the following: - Imperative assignments (e.g. assigning an item to a Button's contentItem in Component.onCompleted). We already encourage declarative bindings rather than imperative assignments. - Using ids in items. Given that these are use cases that we will advise against in the documentation, it's an acceptable compromise. [ChangeLog][Important Behavior Changes] Old delegate items (background, contentItem, etc.) are no longer destroyed, as they are technically owned by user code. Instead, they are hidden, unparented from the control (QQuickItem parent, not QObject), and Accessible.ignored is set to true. This prevents them from being unintentionally visible and interfering with the accessibility tree when a new delegate item is set.

Use qmlRegisterModuleImport() to register styles This patch completes the cumulative work done in previous patches. - Uses qmlRegisterModuleImport() to register styles. This has some added requirements: - Each style must now be a QML module -- that is, it must have a qmldir file. - As a result of the above, the module must be available within the QML import path in order to be found. - The various forms of accepted style names have been reduced down to one ("Material", "MyStyle", etc). See below for an explanation of why. - The following API in QQuickStyle is removed: addStylePath(), availableStyles(), path(), stylePathList(). These no longer make sense now that we reuse the existing QML import system. - Adds the tst_qquickstyleselector auto test back as "styleimports". qmlRegisterModuleImport() vs resolvedUrl() Previously we would use QQuickStyleSelector to select individual QML files based on which style was set. We'd do this once when QtQuick.Controls was first imported. With Qt 6, and the requirement that each style be a proper QML module, qmlRegisterModuleImport() was introduced. This allows us to "link" one import with another. For an example of what this looks like in practice, suppose the style was set to "MyStyle", and the fallback to "Material". The "QtQuick.Controls" import will be linked to "MyStyle", "MyStyle" to "QtQuick.Controls.Material", and as a final fallback (for controls like Action which only the Default style implements), "QtQuick.Controls.Material" to "QtQuick.Controls.Default". This is the same behavior as in Qt 5 (see qquickstyleselector.cpp): // 1) requested style (e.g. "MyStyle", included in d->selectors) // 2) fallback style (e.g. "Material", included in d->selectors) // 3) default style (empty selector, not in d->selectors) This is a necessary step to enable compilation of QML to C++. Reducing the set of accepted style names The problem In QtQuickControls2Plugin() we need to call QQuickStylePrivate::init(baseUrl()) in order to detect if the style is a custom style in QQuickStyleSpec::resolve() (by checking if the style path starts with the base URL). In Qt 5, init() is called in QtQuickControls2Plugin::registerTypes(), but in Qt 6 that's too late, because we need to call qmlRegisterModuleImport() in the constructor. qmlRegisterModuleImport() itself requires the style to have already been set in order to create the correct import URI ("QtQuick.Controls.X" for built-in styles, "MyCustomStyle" for custom styles). The solution By reducing the valid forms for style names down to one: ./myapp -style MyStyle we solve the problem of needing baseUrl() to determine if the style is a custom style or not, but needing to call it too early (since we now call qmlRegisterModuleImport() in QtQuickControls2Plugin(), which itself requires the style to have already been set). baseUrl() can't have been set before the constructor is finished. All of the various forms for _setting_ a style are still valid; environment variables, qtquickcontrols2.conf, etc. [ChangeLog][Important Behavior Changes] Custom styles must now have a qmldir that lists the files that the style implements. For example, for a style that only implements Button: --- module MyStyle Button 1.0 Button.qml --- In addition, there is now only one valid, case-sensitive form for style names: "Material", "MyStyle", etc. These changes are done to help enable the compilation of QML code to C++, as well as improve tooling capabilities. [ChangeLog][Important Behavior Changes] The following API was removed: - QQuickStyle::addStylePath() - QQuickStyle::availableStyles() - QQuickStyle::path() - QQuickStyle::stylePathList() - QT_QUICK_CONTROLS_STYLE_PATH This API is no longer necessary and/or able to be provided now that styles are treated as regular QML modules.
