Description

CircleSegmentSelect is a selection method that selects Segments in response to a mouse click in the graphics window when the Skeleton Selection toolbox is active and is set to “Segment” mode. It selects all Segments lying within a circle swept out by dragging the mouse, as shown in Figure 6.24. Click the mouse in the center of the circle and drag out along a radius. Only Segments lying completely within the circle will be selected.

points is a list of Point objects. The first point in the list is the center of the circle, and the second point is a point on the circumference. Any other points in the list will be ignored.

The shift and ctrl parameters govern how the current selection (i.e, the set of Segments defined by this operation) is merged with the previous selection (the Segments already selected) to form a new selection, as shown in Table 6.1. They indicate whether (1) or not (0) the shift and control keys were depressed during the mouse click that initiated this command.
