The example shows how to: - - \list - \li Create an application with Q3DBars and some widgets - \li Use QBarDataProxy to set data to the graph - \li Adjust some graph properties using widget controls - \endlist - - It also demonstrates how having negative bar values affects the graph. - - \image widget-example.png - - \section1 Creating the application - - First, in main.cpp, we create a QApplication, instantiate Q3DBars and a window container - for it: - - \snippet ../examples/widget/main.cpp 0 - - The call to QWidget::createWindowContainer is required, as all data visualization types - (Q3DBars, Q3DScatter, Q3DSurface) inherit QWindow. Any class inheriting QWindow cannot be used - as a widget any other way. - - Then we'll create horizontal and vertical layouts. We'll add the graph and the vertical - layout into the horizontal one: - - \snippet ../examples/widget/main.cpp 1 - - We're not using the vertical layout for anything yet, but we'll get back to it in - \l {Using widgets to control the graph} - - Next, let's create another class to handle the data addition and other interaction with the - graph. Let's call it GraphModifier (See \l {Setting up the graph} and - \l {Adding data to the graph} for details): - - \snippet ../examples/widget/main.cpp 2 - - The application main is done and we can show the graph and start the event loop: - - \snippet ../examples/widget/main.cpp 3 - - \section1 Setting up the graph - - Let's set up the graph in the constructor of the GraphModifier class we instantiated in the - application main: - - \snippet ../examples/widget/graphmodifier.cpp 0 - - Let's take a closer look at parts of the code. - - First we're creating the axes and the proxy into member variables to support changing them - easily later on, if we want to: - - \snippet ../examples/widget/graphmodifier.cpp 1 - - Then we're setting some of the visual qualities for the graph: - - \snippet ../examples/widget/graphmodifier.cpp 2 - - We're also setting up the axes and adding them to the graph. Notice that we're not setting them - active yet: - - \snippet ../examples/widget/graphmodifier.cpp 3 - - And add the proxy. Note that we're not setting it active yet, but just adding it: - - \snippet ../examples/widget/graphmodifier.cpp 4 - - That concludes setting up the graph. - - \section1 Adding data to the graph - - At the end of the constructor there's a call: - - \code resetTemperatureData(); \endcode - - The method is used to add data to the proxy: - - \snippet ../examples/widget/graphmodifier.cpp 5 - - Now the data is in the proxy, but not in the graph. We have not set the proxy active yet. - - In application main, we called \c {modifier->start()} after constructing all the necessary - objects. This is what is done in it: - - \snippet ../examples/widget/graphmodifier.cpp 6 - - Finally we set the proxy and the axes active. Now our graph has the data and is ready to be - used. - - \section1 Using widgets to control the graph - - There isn't much interaction yet, so let's continue by adding some widgets back in the - application main. Let's just focus on two: - - \snippet ../examples/widget/main.cpp 4 - - We can use these to rotate the graph using slider widgets instead of just using the mouse or - touch. - - Let's add them to the vertical layout we created earlier: - - \snippet ../examples/widget/main.cpp 5 - - Then we'll connect them to methods in GraphModifier: - - \snippet ../examples/widget/main.cpp 6 - - Here are the methods in GraphModifier the signals were connected to: - - \snippet ../examples/widget/graphmodifier.cpp 7 - - Now these two sliders can be used to rotate the graph. - - And so we have an application in which we can control: - - \list - \li Graph rotation - \li Label style - \li Camera preset - \li Background visibility - \li Grid visibility - \li Bar shading smoothness - \li Bar style - \li Selection mode - \li Theme - \li Shadow quality - \li Font - \li Font size - \endlist - - \section1 Example contents - -*/ diff --git a/examples/widget/graphmodifier.cpp b/examples/widget/graphmodifier.cpp deleted file mode 100644 index 0b33bde0..00000000 --- a/examples/widget/graphmodifier.cpp +++ /dev/null @@ -1,229 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2013 Digia Plc -** All rights reserved. -** For any questions to Digia, please use contact form at http://qt.digia.com -** -** This file is part of the QtDataVisualization module. -** -** Licensees holding valid Qt Enterprise licenses may use this file in -** accordance with the Qt Enterprise License Agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and Digia. -** -** If you have questions regarding the use of this file, please use -** contact form at http://qt.digia.com -** -****************************************************************************/ - -#include "graphmodifier.h" -#include <QtDataVisualization/q3dcategoryaxis.h> -#include <QtDataVisualization/q3dvalueaxis.h> -#include <QtDataVisualization/qbardataproxy.h> -#include <QtDataVisualization/q3dscene.h> -#include <QtDataVisualization/q3dcamera.h> -#include <QTime> - -QT_DATAVISUALIZATION_USE_NAMESPACE - -const QString celsiusString = QString(QChar(0xB0)) + "C"; - -//!
