The application uses generated data with - configurable characteristics to mimic a simple oscilloscope user interface. To find out the - actual screen refresh performance of the application, you can set QML_SHOW_FRAMERATE = 1 to - your run environment settings to get the framerate shown in the application output console. - To do so go to Projects - Run - Run environment in Qt Creator and select Add. Then you can - experiment with the different configurable options of the demo application to find the - configuration that gives you the best performance in your environment. - - Note: You can try if enabling OpenGL improves the performance with the following startup - parameter: - \code - -graphicssystem opengl - \endcode - - The application window is shared by control and scope views: - \snippet ../demos/qmloscilloscope/qml/qmloscilloscope/main.qml 1 - \snippet ../demos/qmloscilloscope/qml/qmloscilloscope/main.qml 2 - - ControlView implements the buttons used for configuring. ScopeView uses a ChartView to show - a chart with two line series: - \snippet ../demos/qmloscilloscope/qml/qmloscilloscope/ScopeView.qml 1 - - The data of the line series is updated with a QML timer. In a real life application the - updating could be triggered with a signal from Qt C++ code. - \snippet ../demos/qmloscilloscope/qml/qmloscilloscope/ScopeView.qml 2 - - The oscilloscope also allows you to switch the type of the series used for visualizing the - signal sources. This is implemented by dynamically destroying and creating series: - \snippet ../demos/qmloscilloscope/qml/qmloscilloscope/ScopeView.qml 3 -*/ |
