Inheritance​

Public Methods​

Initializes painter path variables to fit number of channels in the model/view.

Parameters:

  • model : *const QAbstractTableModel ** model.

paint(painter, option, index)​

(sizeHint() must be implemented also)

Parameters:

  • painter : *QPainter ** Low-level painting on widgets and other paint devices.

  • index : const QModelIndex & Used to locate data in a data model.

  • index : const QModelIndex & Used to locate data in a data model.

Returns:

  • QSize — 20 pixels wide by the row height for column 0, the option rectangle size otherwise.

markerMoved(position, activeRow)​

markerMoved is called whenever user moves the mouse inside of the table view viewport

Parameters:

  • position : QPoint The current mouse position.

  • activeRow : int The current row which the mouse is moved over.

setUpperItemIndex(iUpperItemIndex)​
