The \c qmlviewer reads a declarative user interface definition + (\c .qml) file and displays the user interface it describes. + + qmlviewer is a development tool. It is not intended to be + installed in a production environment. + + \section1 Options + + When run with the \c -help option, qmlviewer shows available options. + + \section1 Dummy Data + + One use of qmlviewer is to allow QML files to be viewed stand-alone, + rather than being loaded from within a Qt program. Qt applications will + usually bind objects and properties into the execution context before + running the QML. To stand-in for such bindings, you can provide dummy + data: create a directory called "dummydata" in the same directory as + the target QML file and create files there with the "qml" extension. + All such files will be loaded as QML objects and bound to the root + context as a property with the name of the file (without ".qml"). + + For example, if the Qt application has a "clock.time" property + that is a qreal from 0 to 86400 representing the number of seconds since + midnight, dummy data for this could be provided by \c dummydata/clock.qml: + \code + QtObject { property real time: 12345 } + \endcode + Any QML can be used in the dummy data files. You could even animate the + fictional data! + + \section1 Screen Orientation + + A special piece of dummy data which is integrated into the viewer is + a simple orientation property. The orientation can be set via the + settings menu in the application, or by pressing Ctrl+T to toggle it. + + To use this from within your QML file, import QDeclarativeViewer 1.0 and create a + Screen object. This object has a property, orientation, which can be either + Screen.Landscape or Screen.Portrait and which can be bound to in your + application. An example is below: + +\code + import QDeclarativeViewer 1.0 as QDeclarativeViewer + + Item { + QDeclarativeViewer.Screen { id: qmlviewerScreen } + state: (qmlviewerScreen.orientation == QDeclarativeViewer.Screen.Landscape) ? 'landscape' : '' + } +\endcode + +*/ |
