Digikam::DItemDelegate Class Reference

Inheritance diagram for Digikam::DItemDelegate:

Signals
void	gridSizeChanged (const QSize &newSize)

Public Member Functions
	DItemDelegate (QObject *const parent=nullptr)

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.
