AdfColumnDragSource

public AdfColumnDragSource(): AdfColumnDragSource, for column reordering by drag and drop. Currently only used on touchScreen devices

Method Detail

GetDragOverFeedback

protected Node GetDragOverFeedback(AdfUIInputEvent inputEvent)

Create a node to represent to the user what is being dragged. In this case, the feedback is a DIV that has the dimensions of the column being dragged.

Parameters:

inputEvent - the event triggering the dragging

Return:

Node - the HTML node to use

Overrides:

AdfDragSource.GetDragOverFeedback(AdfUIInputEvent)

_getTable

private AdfRichTable|null _getTable()

Get the table component for this column

Return:: AdfRichTable|null - the table, if found

Init

protected Object Init()

Initialize the class

Return:: Object
Overrides:: AdfObject.Init()

isAvailable

public Boolean isAvailable(AdfDndContext dndContext, Object inputEvent)

Checks if the drag and drop operation should be considered for the given input event. Ensures that the table column reordering has not been disabled, and that the event falls within the column header, and not near an edge, to be considered a resize gesture, or on a sort icon.
