Drag and drop support in Qt is centered around the - QDrag class that handles most of the details of a drag and drop operation. - - The data to be transferred by the drag and drop operation is contained in a - QMimeData object. This is specified with the setMimeData() function in the - following way: - - \snippet doc/src/snippets/dragging/mainwindow.cpp 1 - - Note that setMimeData() assigns ownership of the QMimeData object to the - QDrag object. The QDrag must be constructed on the heap with a parent QWidget - to ensure that Qt can clean up after the drag and drop operation has been - completed. - - A pixmap can be used to represent the data while the drag is in - progress, and will move with the cursor to the drop target. This - pixmap typically shows an icon that represents the MIME type of - the data being transferred, but any pixmap can be set with - setPixmap(). The cursor's hot spot can be given a position - relative to the top-left corner of the pixmap with the - setHotSpot() function. The following code positions the pixmap so - that the cursor's hot spot points to the center of its bottom - edge: - - \snippet doc/src/snippets/separations/finalwidget.cpp 2 - - \note On X11, the pixmap may not be able to keep up with the mouse - movements if the hot spot causes the pixmap to be displayed - directly under the cursor. - - The source and target widgets can be found with source() and target(). - These functions are often used to determine whether drag and drop operations - started and finished at the same widget, so that special behavior can be - implemented. - - QDrag only deals with the drag and drop operation itself. It is up to the - developer to decide when a drag operation begins, and how a QDrag object should - be constructed and used. For a given widget, it is often necessary to - reimplement \l{QWidget::mousePressEvent()}{mousePressEvent()} to determine - whether the user has pressed a mouse button, and reimplement - \l{QWidget::mouseMoveEvent()}{mouseMoveEvent()} to check whether a QDrag is - required. - - \sa {Drag and Drop}, QClipboard, QMimeData, QWindowsMime, QMacPasteboardMime, - {Draggable Icons Example}, {Draggable Text Example}, {Drop Site Example}, - {Fridge Magnets Example} -*/ - -/*! - Constructs a new drag object for the widget specified by \a dragSource. -*/ -QDrag::QDrag(QWidget *dragSource) - : QObject(*new QDragPrivate, dragSource) -{ - Q_D(QDrag); - d->source = dragSource; - d->target = 0; - d->data = 0; - d->hotspot = QPoint(-10, -10); - d->possible_actions = Qt::CopyAction; - d->executed_action = Qt::IgnoreAction; - d->defaultDropAction = Qt::IgnoreAction; -} - -/*! - Destroys the drag object. -*/ -QDrag::~QDrag() -{ - Q_D(QDrag); - delete d->data; - QDragManager *manager = QDragManager::self(); - if (manager && manager->object == this) - manager->cancel(false); -} - -/*! - Sets the data to be sent to the given MIME \a data.

The shortcut - can be set up to contain all the key presses necessary to - describe a keyboard shortcut, including the states of modifier - keys such as \gui Shift, \gui Ctrl, and \gui Alt. - - \target mnemonic - - On certain widgets, using '&' in front of a character will - automatically create a mnemonic (a shortcut) for that character, - e.g. "E&xit" will create the shortcut \gui Alt+X (use '&&' to - display an actual ampersand). The widget might consume and perform - an action on a given shortcut. On X11 the ampersand will not be - shown and the character will be underlined. On Windows, shortcuts - are normally not displayed until the user presses the \gui Alt - key, but this is a setting the user can change. On Mac, shortcuts - are disabled by default. Call qt_set_sequence_auto_mnemonic() to - enable them. However, because mnemonic shortcuts do not fit in - with Aqua's guidelines, Qt will not show the shortcut character - underlined. - - For applications that use menus, it may be more convenient to - use the convenience functions provided in the QMenu class to - assign keyboard shortcuts to menu items as they are created. - Alternatively, shortcuts may be associated with other types of - actions in the QAction class. - - The simplest way to create a shortcut for a particular widget is - to construct the shortcut with a key sequence. For example: - - \snippet doc/src/snippets/code/src_gui_kernel_qshortcut.cpp 0 - - When the user types the \l{QKeySequence}{key sequence} - for a given shortcut, the shortcut's activated() signal is - emitted.
