This virtual function receives events to an object and should return true if the event e was recognized and processed.
The event() function can be reimplemented to customize the behavior of an object.
Make sure you call the parent event class implementation for all the events you did not handle.
Example:
Reimplemented from QObject.
Definition at line 2110 of file qquickcombobox.cpp.
References d, e, QObject::event(), and QEvent::LanguageChange.
Filters events if this object has been installed as an event filter for the watched object.
In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
Example:
Notice in the example above that unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.
Some events, such as \l QEvent::ShortcutOverride must be explicitly accepted (by calling \l {QEvent::}{accept()} on them) in order to prevent propagation.

QQuickComboBox::ImplicitContentWidthPolicy QQuickComboBox::implicitContentWidthPolicy | ( | ) | const |
This property controls how the \l{Control::}{implicitContentWidth} of the ComboBox is calculated.
When the width of a ComboBox is not large enough to display text, that text is elided. Depending on which parts of the text are elided, this can make selecting an item difficult for the end user. An efficient way of ensuring that a ComboBox is wide enough to avoid text being elided is to set a width that is known to be large enough:
However, it is often not possible to know whether or not a hard-coded value will be large enough, as the size of text depends on many factors, such as font family, font size, translations, and so on.
implicitContentWidthPolicy provides an easy way to control how the implicitContentWidth is calculated, which in turn affects the \l{Item::}{implicitWidth} of the ComboBox and ensures that text will not be elided.
The available values are:
\value ContentItemImplicitWidth The implicitContentWidth will default to that of the \l{Control::}{contentItem}. This is the most efficient option, as no extra text layout is done. \value WidestText The implicitContentWidth will be set to the implicit width of the the largest text for the given \l textRole every time the model changes. This option should be used with smaller models, as it can be expensive. \value WidestTextWhenCompleted The implicitContentWidth will be set to the implicit width of the the largest text for the given \l textRole once after \l {QQmlParserStatus::componentComplete()}{component completion}. This option should be used with smaller models, as it can be expensive.
The default value is ContentItemImplicitWidth
.
As this property only affects the implicitWidth
of the ComboBox, setting an explicit \l{Item::}{width} can still result in eliding.
