Constructor Detail

Cursor

public Cursor(Device device,
              int style)

Constructs a new cursor given a device and a style constant describing the desired cursor appearance.

You must dispose the cursor when it is no longer required.

NOTE: It is recommended to use Display.getSystemCursor(int) instead of using this constructor. This way you can avoid the overhead of disposing the Cursor resource.

Parameters:

device - the device on which to allocate the cursor

style - the style of cursor to allocate

Throws:

java.lang.IllegalArgumentException -

• ERROR_NULL_ARGUMENT - if device is null and there is no current device
• ERROR_INVALID_ARGUMENT - when an unknown style is specified

SWTError -

• ERROR_NO_HANDLES - if a handle could not be obtained for cursor creation
