-/*! - * \class Q3DBars - * \inmodule QtDataVis3D - * \brief The Q3DBars class provides methods for rendering 3D bar graphs. - * \since 1.0.0 - * - * This class enables developers to render bar graphs in 3D and to view them by rotating the scene - * freely. Rotation is done by holding down the right mouse button and moving the mouse. Zooming - * is done by mouse wheel. Selection, if enabled, is done by left mouse button. The scene can be - * reset to default camera view by clicking mouse wheel. In touch devices rotation is done - * by tap-and-move, selection by tap-and-hold and zoom by pinch. - * - * Methods are provided for changing bar types, themes, bar selection modes and so on. See the - * methods for more detailed descriptions. - * - * \section1 How to construct a minimal Q3DBars chart - * - * After constructing Q3DBars, you should set data window using setDataWindow(). It is not - * mandatory, as data window has default value of 10 x 10. For the example, let's set the data - * window to 5 rows and 5 columns: - * - * \snippet doc_src_q3dbars_construction.cpp 0 - * - * Now Q3DBars is ready to receive data to be rendered. Add one row of 5 qreals into the data - * set: - * - * \snippet doc_src_q3dbars_construction.cpp 1 - * - * \note We set the sample space to 5 x 5, but we are inserting only one row of data. This is ok, - * the rest of the rows will just be blank. - * - * Finally you will need to set it visible: - * - * \snippet doc_src_q3dbars_construction.cpp 2 - * - * The complete code needed to create and display this chart is: - * - * \snippet doc_src_q3dbars_construction.cpp 3 - * - * And this is what those few lines of code produce: - * - * \image q3dbars-minimal.png - * - * The scene can be rotated, zoomed into, and a bar can be selected to view it's value, - * but no other interaction is included in this minimal code example. You can learn more by - * familiarizing yourself with the examples provided, like the \l{Rainfall Example} or - * the \l{Widget Example}. - * - * If no axes are explicitly set to Q3DBars, temporary default axes with no labels are created. - * These default axes can be modified via axis accessors, but as soon any axis is explicitly - * set for the orientation, the default axis for that orientation is destroyed. - * - * Data proxies work similarly: If no data proxy is explicitly set, Q3DBars creates a default - * proxy. If any other proxy is set as active data proxy later, the default proxy and all data - * added to it is destroyed. - * - * \sa Q3DScatter, Q3DSurface, {Qt Data Visualization 3D C++ Classes} - */ - -/*! - * Constructs a new 3D bar window. - */ -Q3DBars::Q3DBars() - : d_ptr(new Q3DBarsPrivate(this, geometry())) -{ - d_ptr->m_shared->initializeOpenGL(); - QObject::connect(d_ptr->m_shared, &Bars3DController::selectedBarPosChanged, this, - &Q3DBars::selectedBarPosChanged); - QObject::connect(d_ptr->m_shared, &Abstract3DController::needRender, this, - &Q3DWindow::renderLater); -} - -/*! - * Destroys the 3D bar window. - */ -Q3DBars::~Q3DBars() -{ -} - -/*! - * \internal - */ -void Q3DBars::render() -{ - d_ptr->m_shared->synchDataToRenderer(); - d_ptr->m_shared->render(); -} - -#if defined(Q_OS_ANDROID) -/*! - * \internal - */ -void Q3DBars::mouseDoubleClickEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseDoubleClickEvent(event); -} - -/*! - * \internal - */ -void Q3DBars::touchEvent(QTouchEvent *event) -{ - d_ptr->m_shared->touchEvent(event); -} -#endif - -/*! - * \internal - */ -void Q3DBars::mousePressEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mousePressEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DBars::mouseReleaseEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseReleaseEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DBars::mouseMoveEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseMoveEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DBars::wheelEvent(QWheelEvent *event) -{ - d_ptr->m_shared->wheelEvent(event); -} - -/*! - * \internal - */ -void Q3DBars::resizeEvent(QResizeEvent *event) -{ - Q_UNUSED(event); - d_ptr->m_shared->setSize(width(), height()); -} - -/*! - * Sets window \a width. - */ -void Q3DBars::setWidth(const int width) -{ - d_ptr->m_shared->setWidth(width); - QWindow::setWidth(width); -} - -/*! - * Sets window \a height. - */ -void Q3DBars::setHeight(const int height) -{ - d_ptr->m_shared->setHeight(height); - QWindow::setHeight(height); -} - -/*! - * Sets bar specifications.

Rotation is done by holding down the right mouse button and moving the mouse. Zooming - * is done by mouse wheel. Selection, if enabled, is done by left mouse button. The scene can be - * reset to default camera view by clicking mouse wheel. In touch devices rotation is done - * by tap-and-move, selection by tap-and-hold and zoom by pinch. - * - * Methods are provided for changing item styles, themes, item selection modes and so on. See the - * methods for more detailed descriptions. - * - * \section1 How to construct a minimal Q3DScatter chart - * - * First, construct Q3DScatter: - * - * \snippet doc_src_q3dscatter_construction.cpp 0 - * - * Now Q3DScatter is ready to receive data to be rendered. Add one set of 3 QVector3D items: - * - * \snippet doc_src_q3dscatter_construction.cpp 1 - * - * Finally you will need to set it visible: - * - * \snippet doc_src_q3dscatter_construction.cpp 2 - * - * The complete code needed to create and display this chart is: - * - * \snippet doc_src_q3dscatter_construction.cpp 3 - * - * And this is what those few lines of code produce: - * - * \image q3dscatter-minimal.png - * - * The scene can be rotated and zoomed into, but no other interaction is included in this minimal - * code example. You can learn more by familiarizing yourself with the examples provided, like - * the \l{Scatter Chart Example}. - * - * If no axes are explicitly set to Q3DScatter, temporary default axes with no labels are created. - * These default axes can be modified via axis accessors, but as soon any axis is explicitly - * set for the orientation, the default axis for that orientation is destroyed. - * - * Data proxies work similarly: If no data proxy is explicitly set, Q3DScatter creates a default - * proxy. If any other proxy is set as active data proxy later, the default proxy and all data - * added to it is destroyed. - * - * \sa Q3DBars, Q3DSurface, {Qt Data Visualization 3D C++ Classes} - */ - -/*! - * Constructs a new 3D scatter window. - */ -Q3DScatter::Q3DScatter() - : d_ptr(new Q3DScatterPrivate(this, geometry())) -{ - d_ptr->m_shared->initializeOpenGL(); - QObject::connect(d_ptr->m_shared, &Scatter3DController::selectedItemIndexChanged, this, - &Q3DScatter::selectedItemIndexChanged); - QObject::connect(d_ptr->m_shared, &Abstract3DController::needRender, this, - &Q3DWindow::renderLater); -} - -/*! - * Destroys the 3D scatter window. - */ -Q3DScatter::~Q3DScatter() -{ -} - -/*! - * \internal - */ -void Q3DScatter::render() -{ - d_ptr->m_shared->synchDataToRenderer(); - d_ptr->m_shared->render(); -} - -#if defined(Q_OS_ANDROID) -/*! - * \internal - */ -void Q3DScatter::mouseDoubleClickEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseDoubleClickEvent(event); -} - -/*! - * \internal - */ -void Q3DScatter::touchEvent(QTouchEvent *event) -{ - d_ptr->m_shared->touchEvent(event); -} -#endif - -/*! - * \internal - */ -void Q3DScatter::mousePressEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mousePressEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DScatter::mouseReleaseEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseReleaseEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DScatter::mouseMoveEvent(QMouseEvent *event) -{ - d_ptr->m_shared->mouseMoveEvent(event, event->pos()); -} - -/*! - * \internal - */ -void Q3DScatter::wheelEvent(QWheelEvent *event) -{ - d_ptr->m_shared->wheelEvent(event); -} - -/*! - * \internal - */ -void Q3DScatter::resizeEvent(QResizeEvent *event) -{ - Q_UNUSED(event); - d_ptr->m_shared->setSize(width(), height()); -} - -/*! - * Sets window \a width. - */ -void Q3DScatter::setWidth(const int width) -{ - d_ptr->m_shared->setWidth(width); - QWindow::setWidth(width); -} - -/*! - * Sets window \a height. - */ -void Q3DScatter::setHeight(const int height) -{ - d_ptr->m_shared->setHeight(height); - QWindow::setHeight(height); -} - -/*! - * Sets the item \a style to one of the values in \c QDataVis::MeshStyle.
