C allows you to I use cell co-ordinates (like a spreadsheet) to place items on |
|
552
|
|
|
|
|
|
|
an L |
|
553
|
|
|
|
|
|
|
refer to the position of a cell within a row and a column. You define these rows and columns when |
|
554
|
|
|
|
|
|
|
you call the L method. Cell co-ordinates are numbered 1 .. N. |
|
555
|
|
|
|
|
|
|
|
|
556
|
|
|
|
|
|
|
Here, I means all method calls except adding text via the L method. With |
|
557
|
|
|
|
|
|
|
C, you use pixels locations so that the text can be placed anywhere. Pixel co-ordinates are |
|
558
|
|
|
|
|
|
|
numbered 0 .. N. |
