public final class TouchSource extends java.lang.Object
Instances of this class represent sources of touch input that generateTouch
objects. They also provide information about the input source, which is important for interpreting the information in theTouch
object.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 Detail
-
isDirect
public boolean isDirect()
Returns the type of touch input this source generates,true
for direct orfalse
for indirect.- Returns:
true
if the input source is direct, orfalse
otherwise
-
getBounds
public 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 pixels.Note that the x and y values may not necessarily be zero if the TouchSource is a direct source.
- Returns:
- Rectangle The bounding rectangle of the input source.
-
toString
public java.lang.String toString()
Returns a string containing a concise, human-readable description of the receiver.- Overrides:
toString
in classjava.lang.Object
- Returns:
- a string representation of the event
