This is - done by implementing a custom input handler to react to selection signals emitted from the - graph. - - \image draggableaxes-example.png - - \include examples-run.qdocinc - - \section1 Replacing Default Input Handling - - The default input handling mechanism is replaced by setting the active input handler of - Q3DScatter to \c AxesInputHandler that implements the custom behavior: - - \snippet draggableaxes/data.cpp 0 - - \c m_inputHandler was initialized in the constructor: - - \snippet draggableaxes/data.cpp 1 - - We will also need the pointers to the axes, so we will pass them to our input handler too: - - \snippet draggableaxes/data.cpp 2 - - \section1 Extending Mouse Event Handling - - First of all, we inherited our input handler from Q3DInputHandler instead of - QAbstract3DInputHandler. The reason for doing this is to keep all the functionality of the - default input handling, and to add our own functionality on top of it: - - \snippet draggableaxes/axesinputhandler.h 0 - - We start extending the default functionality by re-implementing some of the mouse events. - Let's start with \c {mousePressEvent}. We'll just add button pressed flag for left mouse button - into it, and keep the rest of the default functionality: - - \snippet draggableaxes/axesinputhandler.cpp 0 - - We'll need to modify \c mouseReleaseEvent too to clear the flag and reset the internal state: - - \snippet draggableaxes/axesinputhandler.cpp 1 - - Then we'll modify \c {mouseMoveEvent}. Here we check if the \c m_mousePressed is \c true and - our internal state is something other than \c StateNormal. If so, we'll set the input positions - for mouse move distance calculations and call the axis dragging function (see - \l {Implementing axis dragging} for details): - - \snippet draggableaxes/axesinputhandler.cpp 2 - - We don't need to change the functionality of mouse wheel, so we will not re-implement that. - - \section1 Implementing Axis Dragging - - First we need to start listening to the selection signal from the graph. We do that in the - constructor, and connect it to \c handleElementSelected method: - - \snippet draggableaxes/axesinputhandler.cpp 3 - - In \c handleElementSelected we check the type of the selection and set our internal state based on - it: - - \snippet draggableaxes/axesinputhandler.cpp 4 - - The actual dragging logic is implemented in \c handleAxisDragging method, which we call from - \c mouseMoveEvent in case the required conditions are met: - - \snippet draggableaxes/axesinputhandler.cpp 5 - - In \c handleAxisDragging we first get the scene orientation from our active camera: - - \snippet draggableaxes/axesinputhandler.cpp 6 - - Then we calculate the modifiers to mouse move direction based on the orientation: - - \snippet draggableaxes/axesinputhandler.cpp 7 - - After that, we calculate the mouse movement, and modify it based on the y rotation of the - camera: - - \snippet draggableaxes/axesinputhandler.cpp 8 - - And finally apply the moved distance to the correct axis: - - \snippet draggableaxes/axesinputhandler.cpp 9 - - We also have a function for setting the dragging speed: - - \snippet draggableaxes/axesinputhandler.h 1 - - This is needed, as the mouse movement distance is absolute (in screen coordinates) and we - need to adjust it to the axis range. The larger the value, the slower the dragging will be. - Note that on this example we do not take scene zoom level into account when determining the - drag speed, so you'll notice changes in the range adjustment as you change the zoom level. - - The modifier could be adjusted automatically based on the axis range and camera zoom level, but - we'll leave implementing that as an excercise for the reader. - - \section1 Example Contents -*/ diff --git a/examples/datavisualization/draggableaxes/draggableaxes.pro b/examples/datavisualization/draggableaxes/draggableaxes.pro deleted file mode 100644 index 2f21aee6..00000000 --- a/examples/datavisualization/draggableaxes/draggableaxes.pro +++ /dev/null @@ -1,18 +0,0 @@ -android|ios|winrt { - error( "This example is not supported for android, ios, or winrt." ) -} - -!include( ../examples.pri ) { - error( "Couldn't find the examples.pri file!" ) -} - -SOURCES += main.cpp \ - data.cpp \ - axesinputhandler.cpp -HEADERS += data.h \ - axesinputhandler.h - -QT += widgets - -OTHER_FILES += doc/src/* \ - doc/images/* diff --git a/examples/datavisualization/draggableaxes/main.cpp b/examples/datavisualization/draggableaxes/main.cpp deleted file mode 100644 index 5c7621b0..00000000 --- a/examples/datavisualization/draggableaxes/main.cpp +++ /dev/null @@ -1,78 +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.
