Digikam::DItemDelegate Class Referenceabstract
Inheritance diagram for Digikam::DItemDelegate:

## Signals
void | gridSizeChanged (const QSize &newSize)
void | visualChange ()

## Public Member Functions
| DItemDelegate (QObject *const parent=nullptr)
virtual bool | acceptsActivation (const QPoint &pos, const QRect &visualRect, const QModelIndex &index, QRect *activationRect=nullptr) const =0
virtual bool | acceptsToolTip (const QPoint &pos, const QRect &visualRect, const QModelIndex &index, QRect *tooltipRect=nullptr) const =0
| These methods take four parameters: The position on viewport, the rect on viewport, the index, and optionally a parameter into which, if the return value is true, a rectangle can be written for which the return value will be true as well.
virtual QSize | gridSize () const =0
| Returns the gridsize to be set by the view.
virtual void | mouseMoved (QMouseEvent *e, const QRect &visualRect, const QModelIndex &index)=0
virtual QPixmap | pixmapForDrag (const QStyleOptionViewItem &option, const QList< QModelIndex > &indexes) const =0
virtual void | setDefaultViewOptions (const QStyleOptionViewItem &option)=0
| Style option with standard values to use for cached rendering.
virtual void | setSpacing (int spacing)=0
virtual void | setThumbnailSize (const ThumbnailSize &thumbSize)=0
| You must set these options from the view.

## Static Public Member Functions
static QPixmap | makeDragPixmap (const QStyleOptionViewItem &option, const QList< QModelIndex > &indexes, double displayRatio, const QPixmap &suggestedPixmap=QPixmap())
static QString | squeezedText (const QFontMetrics &fm, int width, const QString &text)

## Protected Member Functions
