List Manager Routines / Changing the Size of Cells and Lists

LCellSize

You can change the size of cells by using the LCellSize procedure. All cells in a list must be the same size, however.

PROCEDURE LCellSize (cSize: Point; lHandle: ListHandle);

cSize

The new size of each cell in the list.

lHandle

The list whose cells' size is being changed.

DESCRIPTION

The LCellSize procedure sets the cellSize field of the list record referenced by the lHandle parameter to the value of the cSize parameter. That is, the list's new cells will be of width cSize.h and of height cSize.v.

The LCellSize procedure updates the list's visible rectangle to contain cells of the specified size. However, LCellSize does not redraw any cells.

SPECIAL CONSIDERATIONS

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