* Encapsulate QQmlContextDataUlf Hermann2020-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This class is not a private detail of QQmlContext. And it is incredibly hard to see who owns what in there. Let's add some civilization ... We enforce refcounting for QQmlContextData across the code base, with two exceptions: 1. QQmlContextPrivate may or may not own its QQmlContextData. 2. We may request a QQmlContextData owned by its parent QQmlContextData. For these two cases we keep flags in QQmlContextData and when the respective field (m_parent or m_publicContext) is reset, we release() once. Furthermore, QQmlContextData and QQmlGuardedContextData are moved to their own files, in order to de-spaghettify qqmlcontext_p.h and qqmlcontext.cpp. When the QQmlEngine is deleted, any QQmlComponents drop their object creators now, in order to release any context data held by those. Before, the context data would be deleted, but the object creators would retain the dangling pointer. [ChangeLog][QML][Important Behavior Changes] QQmlContext::baseUrl() does what the documentation says now: It prefers explicitly set baseUrls over compilation unit URLs. Only if no baseUrl is set, the CU's URL is returned. It used to prefer the CU's URL. Change-Id: Ieeb5dcb07b45d891526191321386d5443b8f5738 Reviewed-by: Fabian Kosmale <fabian.kosmale@qt.io>

* Support required properties in model delegatesFabian Kosmale2019-09-121-0/+1
| | | | | | | | | | | | | | | If a delegates declares a required property of a given name, and that name exists as a role in the model, we set the property accordingly. The same holds true for the special properties that come from the QQmlDelegateModel like "index" and "model". All roles are still injected into scope and thus accessible; changing this in Qt5 would be tedious or even impossible while still maintaining backwardscompatibility with delegates that do not use required properties.

* Introduce required properties to QMLFabian Kosmale2019-09-091-1/+7
| | | | | | | | | | | | | | | | | | | [ChangeLog][QtQml] "required" is now a (contextual) keyword in QML, and users can mark properties with it to specify that those properties must be set when the component gets instantiated. This can be done either declaratively via standard property bindings from QML, or imperatively by using the functions to set initial properties (QQmlCompoent::setInitalProperties and related functions in C++, Qt.createObject, Loader.setSource,... in QML/JS). Logic has been added to QQmlComponent::create and the various QQmlIncubator classes to verify that the required properties were set. If properties marked as required are not set, a warning will be printed at runtime, and the component will not be created.

| | | | | | | | | | | This reverts commit ca6b787a01ea289bd5c2a3e4ff3c7442a4ff58fc. This internal API was added as a workaround for Qt Quick Controls 2.

* Allow canceling incubationJ-P Nurmi2017-01-241-0/+5
| | | | | | | | | | | | Qt Quick Controls must avoid destroying any object that belongs to a tree of objects being incubated. The problem is that QQC have no control over the incubation process. This patch adds private API that allows QQC to cancel incubation of a specific item that QQC would like to destroy.

| | | | | | | | | | | | This removes the bulk of the code. A few smaller cleanups remain, to be done in smaller changes as they move code around. Additionally the "optimize" option of qqmlbundle was removed. It called QQmlScript::Parser::preparseData, which however was not implemented and always returned an empty QByteArray. Therefore "optimize" would not do anything and the class is gone now :) Change-Id: I0c265e756704cb53c5250be1f69e4a3e1b6e64d5 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
