public class PathNodeView

extends TextFieldView

Class PathNodeView uses a TextFieldView to input the single line of text needed to define a PathNode. The data type is fixed to be PathNode.class.

The input format is one of the following:

MOVE[x1;y1]

LINE[x1;y1]

QUAD[x1;y1;x2;y2]

CUBIC[x1;y1;x2;y2;x3;y3]

CLOSE[]

where x1, y1, x2, y2, x3, y3 are floats.

As of 2.6.0a, the methods demandObject and requestObject will return null if the underlying TextFieldView view state consists only of whitespace. This convention is more convenient when interacting with PathListView.

Since:

2.4.0

Version:

2.6.0a
