-- Class: List Control
|
|
-- Basic list control.
|
|
--
|
|
-- This is an abstract base class; derived classes can supply these properties and methods to configure the list control:
|
|
-- .label [Adds a label above the top left corner]
|
|
-- .dragTargetList [List of controls that can receive drag events from this list control]
|
|
-- .showRowSeparators [Shows separators between rows]
|
|
-- :GetRowValue(column, index, value) [Required; called to retrieve the text for the given column of the given list value]
|
|
-- :AddValueTooltip(index, value) [Called to add the tooltip for the given list value]
|
|
-- :GetDragValue(index, value) [Called to retrieve the drag type and object for the given list value]
|
|
-- :CanReceiveDrag(type, value) [Called on drag target to determine if it can receive this value]
|
|
-- :ReceiveDrag(type, value, source) [Called on the drag target when a drag completes]
|
|
-- :OnDragSend(index, value, target) [Called after a drag event]
|
|
-- :OnOrderChange() [Called after list order is changed through dragging]
|
|
-- :OnSelect(index, value) [Called when a list value is selected]
|
|
-- :OnSelClick(index, value, doubleClick) [Called when a list value is clicked]
|
|
-- :OnSelCopy(index, value) [Called when Ctrl+C is pressed while a list value is selected]
|
|
-- :OnSelDelete(index, value) [Called when backspace or delete is pressed while a list value is selected]
|
|
-- :OnSelKeyDown(index, value) [Called when any other key is pressed while a list value is selected]
