Class TouchSource

java.lang.Object
  org.eclipse.swt.widgets.TouchSource

public final class TouchSource

extends Object

Instances of this class represent a source of touch input. It is used to identify which input source generated a Touch object. It also provides information about the input source, which is important when deciding how to interpret the information in the Touch object.

Instances of this class can be marked as direct or indirect:

• When an instance is marked as 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 marked as indirect (or, more precisely, not direct) the touch source is a track pad or other device that normally moves the cursor, but can also interpret multiple touches on its surface. In this case, there is not a one-to-one map 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, false for indirect.

Returns:

boolean If true, the input source is direct. If false, the input source is indirect.

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 String toString()

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

Returns:

a string representation of the event
