We use the \c onClicked signal handler to call the StackView \c pop() function that pops off the page when users tap the button: \printuntil pop() \printuntil } \printuntil } We use the \c opacity property to hide the back button on the main page. We use a \l Text type to display the application name: \printuntil text: \printuntil } The \c x position of the \l Text type is bound to the position and width of the back button, and animated using a \l Behavior. We use a ListModel type that contains ListElement definitions to define titles and source files for the other pages in the application: \skipto ListModel \printuntil ListPage \printuntil } \printuntil } \section1 Navigating in the Application We implement a stack-based navigation model to link the application pages together. Items are pushed onto the stack as users navigate deeper into the application, and popped off again when they return to the main page. In main.qml, we add a \l StackView type as a child of the application window: \skipto StackView \printuntil } The stack is used by invoking its navigation methods. To load the first item in the stack view, we assign it to \c initialItem: \printuntil \printuntil /^\}/ We use a ListView type to display a list of the items provided by \c pageModel. The \c AndroidDelegate custom type defines each item instantiated by the view. \section1 Creating Push Buttons and Switches In ButtonPage.qml we use the \l Button type to create two buttons that change color when users tap them and one that pops off the page and returns the user to the main page: \quotefromfile touch/content/ButtonPage.qml \skipto Button \printuntil stackView \printuntil } We use a \l Switch type to create two switches that users can turn on and off. They are placed within a \l Row type to lay them out horizontally: \printuntil switchStyle \printuntil switchStyle \printuntil } \printuntil } A \l ButtonStyle type creates a custom appearance for the buttons: \skipto Component \printuntil } To use Qt Quick Controls Styles, we must import them: \code import QtQuick.Controls.Styles 1.1 \endcode A \l SwitchStyle type creates a custom appearance for the switches: \quotefromfile touch/content/ButtonPage.qml \skipuntil Component \skipto Component \printuntil /^\}/ The \c groove property holds the background groove of the switch and the \c handle property defines the switch handle. \section1 Creating Sliders In SliderPage.qml, we use a \l Slider type to create three horizontal sliders that are placed within a \l Column type to lay them out in a column: \quotefromfile touch/content/SliderPage.qml \skipto Column \printuntil 1.0 \printuntil } \printuntil } The \c value property holds the initial handle position on the slider. A SliderStyle type creates a custom appearance for the sliders: \printuntil /^\}/ The \c handle property defines the slider handle and the \c groove property holds the background groove of the slider. \section1 Indicating Progress In ProgressBar.qml, we use a ProgressBar type to create three progress bars: \quotefromfile touch/content/ProgressBarPage.qml \skipto Column \printuntil 1 \printuntil 400 \printuntil } We use a NumberAnimation type with a SequentialAnimation type to run two number animations in a sequence. We apply the animations on the \c progress custom property to animate the current value on the progress bars: \quotefromfile touch/content/ProgressBarPage.qml \skipto progress \printuntil } \printuntil } A ProgressBarStyle type creates a custom appearance for the progress bars: \quotefromfile touch/content/ProgressBarPage.qml \skipto Component \printuntil /^\}/ \section1 Creating Tabs In TabBarPage.qml, we use a TabView type with a \l Tab type to provide a tab-based navigation model for our application. We use tabs to display the ButtonPage, SliderPage, and ProgressBarPage on separate tab pages: \quotefromfile touch/content/TabBarPage.qml \skipto TabView \printuntil ProgressBarPage \printuntil } A TabViewStyle type creates a custom appearance for the tabs: \skipto Component \printuntil /^\}/ \section1 Creating Text Input Fields In the TextInputPage.qml, we use a TextField type to create an input field and a read-only text field: \quotefromfile touch/content/TextInputPage.qml \skipto Column \printuntil true \printuntil } \printuntil } A TextFieldStyle creates a custom appearance for the text fields: \printuntil /^\}/ We use a BorderImage type with an image to create borders for the fields. \section1 Creating Scrolling Lists In ListPage.qml, we use a ScrollView type to provide a scrolling page with a vertical scoll bar: \quotefromfile touch/content/ListPage.qml \skipto ScrollView \printuntil true We use a ListView type to display a list of 100 items by specifying an \l{Models and Views in Qt Quick#Integers as Models}{integer} as the value of the \c model property. We reuse the \c AndroidDelegate custom type here to define each item instantiated by the view. The \c text property adds the string \c {Item #} to each list item: \printuntil } \printuntil } A ScrollViewStyle type creates a custom appearance for the scroll view: \printuntil /^\}/ The \c transientScrollBars property is set to \c true to make the scroll bars appear when the content is scrolled and disappear when they are no longer needed. The \c handle property controls the appearance of the scroll bar handle and the \c scrollBarBackground property that of the background. */ /*! \example calendar \title Qt Quick Controls - Calendar Example \ingroup qtquickcontrols_examples \brief Demonstrates the use of Calendar control \image qtquickcontrols-example-calendar.png The Calendar example displays a Calendar control and an events list for the selected date. It uses a C++ class to fetch the event details from an SQLite database. The example app uses a custom CalendarStyle to highlight the selected date and mark the dates that have events. The following snippet from \e main.qml shows how the Calendar control is used in the app: \code Calendar { id: calendar width: (parent.width > parent.height ? parent.width * 0.6 - parent.spacing : parent.width) height: (parent.height > parent.width ? parent.height * 0.6 - parent.spacing : parent.height) frameVisible: true weekNumbersVisible: true selectedDate: new Date(2014, 0, 1) focus: true style: CalendarStyle { dayDelegate: Item { ... } } } \endcode The C++ class, SqlEventModel, inherits SqlQueryModel to create a database with dummy events for certain dates. \quotefromfile calendar/src/sqleventmodel.cpp \skipto SqlEventModel::SqlEventModel() \printto QList \skipto void SqlEventModel \printuntil /\^} In \e main.qml, the SqlEventModel custom type is used to get the list of events to mark the dates on the calendar. \code SqlEventModel { id: eventModel } Calendar { ... style: CalendarStyle { dayDelegate: Item { ... Image { visible: eventModel.eventsForDate(styleData.date).length > 0 ... source: "qrc:/images/eventindicator.png" } } } } \endcode The app uses a Flow type to position the items, and manipulates the items' width and height based on the orientation change on mobile devices. \code Calendar { id: calendar width: (parent.width > parent.height ? parent.width * 0.6 - parent.spacing : parent.width) height: (parent.height > parent.width ? parent.height * 0.6 - parent.spacing : parent.height) } Rectangle { width: (parent.width > parent.height ? parent.width * 0.4 - parent.spacing : parent.width) height: (parent.height > parent.width ? parent.height * 0.4 - parent.spacing : parent.height) border.color: Qt.darker(color, 1.2) ListView { ... } } \endcode \include examples-run.qdocinc */ /*! \example styles \title Qt Quick Controls - Styles Example \ingroup qtquickcontrols_examples \brief Demonstrates custom styles \image qtquickcontrols-example-styles.png This example shows how to create custom styles for \l{Qt Quick Controls}. \include examples-run.qdocinc */
