public final class TouchSource extends Object
Instances of this class represent sources of touch input that generate
Touchobjects. They also provide information about the input source, which is important for interpreting the information in the
Instances of this class can be marked as direct or indirect:
- When an instance is direct, the touch source is a touch-sensitive digitizer surface such as a tablet or a touch screen. There is a one-to-one mapping between a touch point and a location in a window.
- When an instance is indirect (more precisely, not direct), the touch source is a track pad or other device that normally moves the cursor, but is also able to interpret multiple touches on its surface. In this case there is not a one-to-one mapping between the location of the touch on the device and a location on the display because the user can remove their finger or stylus and touch another part of the device and resume what they were doing.
Method SummaryModifier and TypeMethodDescriptionReturns the bounding rectangle of the device.
isDirect()Returns the type of touch input this source generates,

toString()Returns a string containing a concise, human-readable description of the receiver.

getBoundspublic Rectangle getBounds()Returns the bounding rectangle of the device. For a direct source, this corresponds to the bounds of the display device in pixels. For an indirect source, this contains the size of the device in points.
Note that the x and y values may not necessarily be 0 if the TouchSource is a direct source.
