Home Qt 5.11 Qt Widgets Drag and Drop Robot Example Demonstrates how to drag and drop items in a graphics view. The Drag and Drop Robot example shows how to implement Drag and Drop in a QGraphicsItem subclass, as well as how to animate items using Qt's Animation Framework. Graphics View provides the QGraphicsScene class for managing and interacting with a large number of custom-made 2D graphical items derived from the QGraphicsItem class, and a QGraphicsView widget for visualizing the items, with support for zooming and rotation. This example consists of a Robot class, a ColorItem class, and a main function: the Robot class describes a simple robot consisting of several RobotPart derived limbs, including RobotHead and RobotLimb, the ColorItem class provides a draggable colored ellipse, and the main() function provides the main application window. We will first review the Robot class to see how to assemble the different parts so that they can be individually rotated and animated using QPropertyAnimation, and we will then review the ColorItem class to demonstrate how to implement Drag and Drop between items. Finally we will review the main() function to see how we can put all the pieces together, to form the final application.Robot Class Definition The robot consists of three main classes: the RobotHead, the RobotTorso, and the RobotLimb, which is used for the upper and lower arms and legs. All parts derive from the RobotPart class, which in turn inherits QGraphicsObject. The Robot class itself has no visual appearance and serves only as a root node for the robot. Let's start with the RobotPart class declaration. class RobotPart : public QGraphicsObject{public: RobotPart(QGraphicsItem *parent = 0);protected: void dragEnterEvent(QGraphicsSceneDragDropEvent *event) override; void dragLeaveEvent(QGraphicsSceneDragDropEvent *event) override; void dropEvent(QGraphicsSceneDragDropEvent *event) override; QColor color; bool dragOver;}; This base class inherits QGraphicsObject. QGraphicsObject provides signals and slots through inheriting QObject, and it also declares QGraphicsItem's properties using Q_PROPERTY, which makes the properties accessible for QPropertyAnimation. RobotPart also implements the three most important event handlers for accepting drop events: dragEnterEvent(), dragLeaveEvent(), and dropEvent(). The color is stored as a member variable, along with the dragOver variable, which we will use later to indicate visually that the limb can accept colors that are is dragged onto it. RobotPart::RobotPart(QGraphicsItem *parent) : QGraphicsObject(parent), color(Qt::lightGray), dragOver(false){ setAcceptDrops(true);} RobotPart's constructor initializes the dragOver member and sets the color to Qt::lightGray. In the constructor body we enable support for accepting drop events by calling setAcceptDrops(true). The rest of this class's implementation is to support Drag and Drop. void RobotPart::dragEnterEvent(QGraphicsSceneDragDropEvent *event){ if (event->mimeData()->hasColor()) { event->setAccepted(true); dragOver = true; update(); } else { event->setAccepted(false); }} The dragEnterEvent() handler is called when a Drag and Drop element is dragged into the robot part's area. The handler implementation

Skip to contentIn this Robot Framework Tutorial we will understand how to handle mouse actions in Robot Framework and the keywords available in Robot Selenium library to handle mouse actions like, mouse hover, mouse out, Drag And Drop, Right click etc.Some of the keywords that I will explain in this tutorial are:* Mouse Down – Simulates pressing the left mouse button on the element locator* Mouse Down On Image – Simulates a mouse down event on an image identified by locator* Mouse Down On Link – Simulates a mouse down event on a link identified by locator* Mouse Up – Simulates releasing the left mouse button on the element locator* Mouse Over – Simulates hovering the mouse over the element locator* Mouse Out – Simulates moving the mouse away from the element locator* Open Context Menu – Right Click Operations – Opens the context menu on the element identified by locator* Drag And Drop – Drags the element identified by locator into the target element* Drag And Drop By Offset – Drags the element identified with locator by xoffset/yoffset.

Painter(&pixmap); painter.translate(15, 15); painter.setRenderHint(QPainter::Antialiasing); paint(&painter, 0, 0); painter.end(); pixmap.setMask(pixmap.createHeuristicMask()); drag->setPixmap(pixmap); drag->setHotSpot(QPoint(15, 20)); } Otherwise, and this is the most common outcome, a simple color is assigned to the drag object's mime data. We render this ColorItem into a new pixmap to give the user visual feedback that the color is being "dragged". drag->exec(); setCursor(Qt::OpenHandCursor);} Finally we execute the drag. QDrag::exec() will reenter the event loop, and only exit if the drag has either been dropped, or canceled. In any case we reset the cursor to Qt::OpenHandCursor.The main() Function Now that the Robot and ColorItem classes are complete, we can put all the pieces together inside the main() function. int main(int argc, char **argv){ QApplication app(argc, argv); We start off by constructing QApplication, and initializing the random number generator. This ensures that the color items have different colors every time the application starts. QGraphicsScene scene(-200, -200, 400, 400); for (int i = 0; i 10; ++i) { ColorItem *item = new ColorItem; item->setPos(::sin((i * 6.28) / 10.0) * 150, ::cos((i * 6.28) / 10.0) * 150); scene.addItem(item); } Robot *robot = new Robot; robot->setTransform(QTransform::fromScale(1.2, 1.2), true); robot->setPos(0, -20); scene.addItem(robot); We construct a fixed size scene, and create 10 ColorItem instances arranged in a circle. Each item is added to the scene. In the center of this circle we create one Robot instance. The robot is scaled and moved up a few units. It is then added to the scene. GraphicsView view(&scene); view.setRenderHint(QPainter::Antialiasing); view.setViewportUpdateMode(QGraphicsView::BoundingRectViewportUpdate); view.setBackgroundBrush(QColor(230, 200, 167)); view.setWindowTitle("Drag and Drop Robot"); view.show(); return app.exec();} Finally we create a QGraphicsView window, and assign the scene to it. For increased visual quality, we enable antialiasing. We also choose to use bounding rectangle updates to simplify visual update handling. The view is given a fixed sand-colored background, and a window title. We then show the view. The animations start immediately after control enters the event loop.
