Figure 6-19 Scrubbing a little or a lot

The effect of scrubbing may be different if a user ﬁrst selects several objects.

If a user selects several objects, contiguous or not, and then scrubs over all or

any part of the selected objects, all the selected objects are deleted. Unselected

objects, if any, are not deleted by this scrub. However, if nothing is selected,

all objects touched by the scrubbing gesture are deleted.

Your application doesn’t have to do anything to handle scrubbing in input

areas that are based on Newton prototypes. If you make other input areas,

you must program them to recognize the scrubbing gesture, play the poof

sound, and display the dissipating smoke animation sequence. Scale the

smoke cloud to the size of the user’s zigzag gesture, keeping the height and

width proportional to the original image’s dimensions. Do not scale the

smoke cloud down so much that it becomes unrecognizable, even if the zigzag

gesture is very small.
