\qmltype TabWidget
\inqmlmodule UIComponents
\brief A widget that places its children as tabs.
A TabWidget places its children as tabs in a view. Selecting
a tab involves selecting the tab at the top.
The TabWidget component is part of the \l {UI Components} module.
This documentation is part of the \l{componentset}{UIComponents} example.
\section1 Adding Tabs
To add a tab, declare the tab as a child of the TabWidget.
\code
TabWidget {
id: tabwidget
Rectangle {
id: tab1
color: "red"
//... omitted
}
Rectangle {
id: tab2
color: "blue"
//... omitted
}
}
\endcode
*/
Item {
id: tabWidget
/*!
\internal
Setting the default property to stack.children means any child items
of the TabWidget are actually added to the 'stack' item's children.
See the \l{"Property Binding in QML"}
documentation for details on default properties.
This is an implementation detail, not meant for public knowledge. Putting
the \internal command at the beginning will cause QDoc to not publish this
documentation in the public API page.
Normally, a property alias needs to have a
"\qmlproperty <type> <propertyname>" to assign the alias a type.
*/
default property alias content: stack.children
/*!
The currently active tab in the TabWidget.
*/
property int current: 0
/*!
A sample \c{read-only} property.
A contrived property to demonstrate QDoc's ability to detect
read-only properties.
The signature is:
\code
readonly property int sampleReadOnlyProperty: 0
\endcode
Note that the property must be initialized to a value.
*/
readonly property int sampleReadOnlyProperty: 0
/*!
\internal
This handler is an implementation
detail. The \c{\internal} command will prevent QDoc from publishing this
documentation on the public API.
*/
onCurrentChanged: setOpacities()
Component.onCompleted: setOpacities()
/*!
\internal
An internal function to set the opacity.
The \internal command will prevent QDoc from publishing this
documentation on the public API.
