## Functions

getCacheFrom(This)

For `EVT_LIST_CACHE_HINT` event only: return the first item which the list control advises us to cache.

getCacheTo(This)

For `EVT_LIST_CACHE_HINT` event only: return the last item (inclusive) which the list control advises us to cache.

getColumn(This)

The column position: it is only used with `COL` events.

getData(This)

The data.

getImage(This)

The image.

getIndex(This)

The item index.

getItem(This)

An item object, used by some events.

getKeyCode(This)

Key code if the event is a keypress event.

getLabel(This)

The (new) item label for `EVT_LIST_END_LABEL_EDIT` event.

getMask(This)

The mask.

getPoint(This)

The position of the mouse pointer if the event is a drag event.

getText(This)

The text.

isEditCancelled(This)

This method only makes sense for `EVT_LIST_END_LABEL_EDIT` message and returns true if it the label editing has been cancelled by the user (`getLabel/1` returns an empty string in this case but it doesn't allow the application to distinguish between really cancelling the edit and the admittedly rare case when the user wants to rename it to an empty string).
