Method Detail

addWindow

void addWindow(DnDObject win)

Adds a DnDObject to the end of this column

Parameters:

win - The object to be added

fixRowNums

void fixRowNums()

Each DnDObject has a 'row number' which is an index of where the item is vertically in the column. This method will iterate over each DnDObject in the column and ensure that its row number is one more than the previous element.

getColumnNumber

int getColumnNumber()

Returns the column index for this column.

Returns:

A 1 indexed number indicating the position from left to right of this column

onDrop

void onDrop(DropEvent event)

This method handles the drop event for the column

Parameters:

event - The event object passed from ZK

reBuildList

void reBuildList()

Fixes the row numbers (fixRowNums()) and then redraws the column.

removeWindow

void removeWindow(DnDObject win)

Removed a DnDObject from this column

Parameters:

win - The object to be removed

sortList

void sortList()

Sorts the internal column list according to the DnDObject's comparator
