| HoverButtonDelegateOverlay (QObject *const parent) | |
| ItemViewHoverButton * | button () const |
| void | setActive (bool active) override |
| Will call createButton(). | |
Public Member Functions inherited from Digikam::AbstractWidgetDelegateOverlay | |
| AbstractWidgetDelegateOverlay (QObject *const parent) | |
| This class provides functionality for using a widget in an overlay. | |
Public Member Functions inherited from Digikam::ItemDelegateOverlay | |
| ItemDelegateOverlay (QObject *const parent=nullptr) | |
| virtual bool | acceptsDelegate (QAbstractItemDelegate *) const |
| QAbstractItemDelegate * | delegate () const |
| virtual void | mouseMoved (QMouseEvent *e, const QRect &visualRect, const QModelIndex &index) |
| Only these two methods are implemented as virtual methods. | |
| virtual void | paint (QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index) |
| void | setDelegate (QAbstractItemDelegate *delegate) |
| void | setView (QAbstractItemView *view) |

Protected Slots | |
| void | slotEntered (const QModelIndex &index) override |
| void | slotReset () override |
Protected Slots inherited from Digikam::AbstractWidgetDelegateOverlay | |
| virtual void | slotEntered (const QModelIndex &index) |
| Default implementation shows the widget iff the index is valid and checkIndex returns true. | |
| virtual void | slotLayoutChanged () |
| virtual void | slotReset () |
| Default implementations of these three slots call hide() | |
| virtual void | slotRowsRemoved (const QModelIndex &parent, int start, int end) |
| virtual void | slotViewportEntered () |
Protected Slots inherited from Digikam::ItemDelegateOverlay | |
Protected Member Functions | |
| virtual ItemViewHoverButton * | createButton ()=0 |
| Create your widget here. | |
| QWidget * | createWidget () override |
| Create your widget here. | |
| virtual void | updateButton (const QModelIndex &index)=0 |
| Called when a new index is entered. | |
| void | visualChange () override |
| Called when any change from the delegate occurs - when the overlay is installed, when size hints, styles or fonts change. | |
Protected Member Functions inherited from Digikam::AbstractWidgetDelegateOverlay | |
| virtual bool | checkIndex (const QModelIndex &index) const |
| bool | checkIndexOnEnter (const QModelIndex &index) const |
| Utility method called from slotEntered. | |
| bool | eventFilter (QObject *obj, QEvent *event) override |
| virtual void | hide () |
| Called when the widget shall be hidden (mouse cursor left index, viewport, uninstalled etc.). | |
| virtual QString | notifyMultipleMessage (const QModelIndex &, int number) |
| QWidget * | parentWidget () const |
| virtual void | viewportLeaveEvent (QObject *obj, QEvent *event) |
| Called when a QEvent::Leave of the viewport is received. | |
| virtual void | widgetEnterEvent () |
| Called when a QEvent::Enter resp. | |
| void | widgetEnterNotifyMultiple (const QModelIndex &index) |
| A sample implementation for above methods. | |
| virtual void | widgetLeaveEvent () |
| void | widgetLeaveNotifyMultiple () |
Protected Member Functions inherited from Digikam::ItemDelegateOverlay | |
| QList< QModelIndex > | affectedIndexes (const QModelIndex &index) const |
| bool | affectsMultiple (const QModelIndex &index) const |
| For the context that an overlay can affect multiple items: Assuming the currently overlayed index is given. | |
| int | numberOfAffectedIndexes (const QModelIndex &index) const |
| bool | viewHasMultiSelection () const |
| Utility method. | |
