import QtQuick 1.0 /*! \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.
