Class X11Cursor

java.lang.Object

com.sun.glass.ui.monocle.NativeCursor

com.sun.glass.ui.monocle.X11Cursor

Direct Known Subclasses:

X11WarpingCursor

public class X11Cursor
extends NativeCursor

Provides a native cursor for use with X11. Since X11 doesn't provide any programmatic way to dynamically hide/show the cursor, we use a workaround of creating a 1x1 transparent pixmap cursor which we activate whenever we want to hide the cursor.
