* Fix issue with bindings to aliases that cannot yet be resolvedErik Verbruggen2018-03-151-0/+1
| | | | | | | | | | | | | | | When an alias points to a child object which has not yet been initialized, it's id won't have been registered yet, so setting up a binding to it will result in a crash. The fix is: when setting a binding target fails, and its target property is an alias, queue them until all bindings have been set up, and try again.

* Optimize QQmlProperty constructor for the common property caseSimon Hausmann2018-01-171-66/+70
| | | | | | | | | | | | | The common case is that QQmlProperty is constructed on the property of an object, not a group property. Therefore we should do the QVector<QStringRef> split on the property name by '.' only if a dot exists, and can avoid the allocation and deallocation of the vector. Shaves off ~1.2% off delegates_item_states.qml. Task-number: QTBUG-65708 Change-Id: Iffbde176e616beec0ae0a47216360558adc793ee Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Speed up PropertyChange state applicationSimon Hausmann2018-01-171-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every time we decode a potential binding of a PropertyChanges{} object, we call qmlContext(this) and we go through a full QQmlProperty construction (which involves property name decoding by dots and property lookups), just to determine if we're doing a binding on a property or a signal. QQmlProperty::isSignalProperty() will only return true if the property is valid and if it's a "function" type. The QQmlProperty constructor on the other hand only constructs a valid regular property if it's _not_ a function type and a signal property _has_ to start with "on" followed by an upper case character. We can copy this shortcut out into decodeBinding() to avoid the QQmlProperty construction in the common case of plain property bindings. This is also legit in the scope of group properties, as signal bindings on group properties are not supported (we always use the state's target object for signal lookup, never the group object). In addition, avoid creating a public QQmlContext for the PropertyChange object by allowing for the construction of the QQmlProperty object via the QQmlContextData, as that's the only data structure we really need. These two changes used to be separate, but they need to go together to keep the tests passing, as the property validation and warning issuing is now moved from decodeBinding() into ::actions() itself.

| * Avoid access to declarativeData when isDeletingChildren is setBernhard Übelacker2017-04-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QObject's members declarativeData and currentChildBeingDeleted share the same memory because they are inside a union. This leads to a problem when destructing mixed Widgets and QML objects. Then in QObjectPrivate::deleteChildren the member currentChildBeingDeleted is set. But unfortunatley QObjectWrapper::destroyObject retrieves the same pointer via declarativeData. This patch should avoid this by disallowing retrieval of declarativeData when isDeletingChildren is set (or at least adds a Q_ASSERT).

* Fix conversion between char and string.Christian Strømme2015-03-211-2/+24
| | | | | | | | | | | | | | | | | | | | | | | If a QChar (or char) was used to set a QString property, the intermediate value used by the QML engine (int), would be converted to a string representation of the integer and not the actual character. To avoid this behavior, characters are now stored as string objects and the string is then converted to the target char type if possible. A side effect of this solution is that it is makes it possible to assign a string to a char property as well, but only if the string contains exactly one character. [ChangeLog][QtQml][Important Behavior Changes] Assigning a char to a string will now create a string with the actual character instead of a string representation of the character's code-point. A side effect of this change is that a one-character string also can be assigned to a character type.
