Standard Widget Toolkit for GTK 3.125.0 · org.eclipse.swt.widgets.TouchSource

Instances of this class represent sources of touch input that generate Touch objects. They also provide information about the input source, which is important for interpreting the information in the Touch 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.

Parameters

direct:boolean: Is the touch source direct or indirect?

Method Detail

getBounds	back to summary
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 points. Note that the x and y values may not necessarily be 0 if the TouchSource is a direct source. Returns:Rectangle the bounding rectangle of the input source

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 points.

Note that the x and y values may not necessarily be 0 if the TouchSource is a direct source.

Returns:Rectangle: the bounding rectangle of the input source

isDirect	back to summary
public boolean isDirect() Returns the type of touch input this source generates, `true` for direct or `false` for indirect. Returns:boolean `true` if the input source is direct, or `false` otherwise

public boolean isDirect()

Returns the type of touch input this source generates, true for direct or false for indirect.

Returns:boolean: true if the input source is direct, or false otherwise
