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.
