The data is cached in a format accepted by QSurfaceDataProxy: - - \snippet qml3doscilloscope/datasource.cpp 0 - - The second method, \c update(), copies one set of the cached data into another array, which we - set to the data proxy of the series by calling QSurfaceDataProxy::resetArray(). - We reuse the same array if the array dimensions have not changed to minimize overhead: - - \snippet qml3doscilloscope/datasource.cpp 1 - - \note Even though we are operating on the array pointer we have previously set to the proxy - we still need to call QSurfaceDataProxy::resetArray() after changing the data in it to prompt - the graph to render the data. - - To be able to access the \c DataSource methods from QML, we need to expose it. We do this by - defining a context property in application main: - - \snippet qml3doscilloscope/main.cpp 0 - - To make it possible to use QSurface3DSeries pointers as parameters on the - \c DataSource class methods on all environments and builds, we need to make sure the meta - type is registered: - - \snippet qml3doscilloscope/datasource.cpp 3 - \dots 0 - \snippet qml3doscilloscope/datasource.cpp 4 - - \section1 QML - - In the QML codes, we define a Surface3D graph normally and give it a Surface3DSeries: - - \snippet qml3doscilloscope/qml/qml3doscilloscope/main.qml 0 - - One interesting detail is that we don't specify a proxy for the Surface3DSeries we attach - to the graph. This makes the series to utilize the default QSurfaceDataProxy. - - We also hide the item label with \l{Abstract3DSeries::itemLabelVisible}{itemLabelVisible}, since - we want to display the selected item information in a \c Text element instead of a floating - label above the selection pointer. - This is done because the selection pointer moves around a lot as the data changes, which makes - the regular selection label difficult to read. - - We initialize the \c DataSource cache when the graph is complete by calling a helper function - \c generateData(), which calls the method with the same name on the \c DataSource: - - \snippet qml3doscilloscope/qml/qml3doscilloscope/main.qml 2 - \dots 4 - \snippet qml3doscilloscope/qml/qml3doscilloscope/main.qml 4 - - To trigger the updates in data, we define a \c Timer item which calls the \c update() method on the \c - DataSource at requested intervals. The label update is also triggered on each cycle: - - \snippet qml3doscilloscope/qml/qml3doscilloscope/main.qml 3 - - \section1 Enabling Direct Rendering - - Since this application potentially deals with a lot of rapidly changing data, we use direct - rendering mode for performance. To enable antialiasing in this mode the surface format of the application - window needs to be changed, as the default format used by QQuickView doesn't support antialiasing. - We use the utility function provided by Qt Data Visualization to change the surface format - in \c main.cpp: - - \snippet qml3doscilloscope/main.cpp 1 - \dots 0 - \snippet qml3doscilloscope/main.cpp 2 - -*/ diff --git a/examples/datavisualization/qml3doscilloscope/main.cpp b/examples/datavisualization/qml3doscilloscope/main.cpp deleted file mode 100644 index fef0f30e..00000000 --- a/examples/datavisualization/qml3doscilloscope/main.cpp +++ /dev/null @@ -1,77 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2016 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the Qt Data Visualization module of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:GPL$ -** Commercial License Usage -** Licensees holding valid commercial Qt licenses may use this file in -** accordance with the commercial license agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and The Qt Company.
