itemsSelected in interface IColumnCategoriesDialogListener

itemsMoved

public void itemsMoved(SelectionLayer.MoveDirectionEnum direction,
                       List<Integer> selectedPositions)

Moves the columns up or down by firing commands on the dialog. Individual columns are moved using the ColumnReorderCommand Contiguously selected columns are moved using the MultiColumnReorderCommand

Specified by:

itemsMoved in interface IColumnCategoriesDialogListener

Parameters:

direction - the direction to move

selectedPositions - the column positions to move

getDestinationPositions

protected List<Integer> getDestinationPositions(SelectionLayer.MoveDirectionEnum direction,
                                                List<List<Integer>> selectedPositions)

Calculates the destination positions taking into account the move direction and single/contiguous selection.

Parameters:

direction - the direction to move

selectedPositions - grouped together if they are contiguous.

Example: if 2,3,4, 9, 12 are selected, they are grouped as [[2, 3, 4], 9, 12]

• While moving up the destination position for [2, 3, 4] is 1
• While moving up the destination position for [2, 3, 4] is 6

Returns:

a List of destination positions
