Member Function Documentation

acceptsActivation()

virtual bool Digikam::DItemDelegate::acceptsActivation ( const QPoint &  pos, const QRect &  visualRect, const QModelIndex &  index, QRect *  activationRect = nullptr  ) const

pure virtual

Implemented in Digikam::ItemViewImportDelegate, Digikam::ImportDelegate, ShowFoto::ShowfotoItemViewDelegate, ShowFoto::ShowfotoDelegate, Digikam::ItemViewDelegate, Digikam::ItemDelegate, Digikam::ImportThumbnailDelegate, ShowFoto::ShowfotoThumbnailDelegate, and Digikam::ItemThumbnailDelegate.

acceptsToolTip()

virtual bool Digikam::DItemDelegate::acceptsToolTip ( const QPoint &  pos, const QRect &  visualRect, const QModelIndex &  index, QRect *  tooltipRect = nullptr  ) const

pure virtual

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.

Implemented in Digikam::ItemViewImportDelegate, Digikam::ImportDelegate, ShowFoto::ShowfotoItemViewDelegate, ShowFoto::ShowfotoDelegate, Digikam::ItemViewDelegate, and Digikam::ItemDelegate.
