LLastClick

You can use the LLastClick function to determine the coordinates of the last cell clicked in a particular list.

FUNCTION LLastClick (lHandle: ListHandle): Cell;

lHandle

The list to be checked for the last cell clicked.

DESCRIPTION

The LLastClick function returns the cell coordinates of the last cell clicked. If the user has not clicked a cell since the creation of the list, then both the h and v fields of the cell returned contain negative numbers.

Note that the last cell clicked is not necessarily the last cell selected. The user could Shift-click in one cell and then drag the cursor to select other cells.

SPECIAL CONSIDERATIONS

You should not call the LLastClick function from within an interrupt, such as in a completion routine or VBL task.
