public Class X11Cursor

extends NativeCursor
Class Inheritance
Known Direct Subclasses
com.sun.glass.ui.monocle.X11WarpingCursor
Imports
com.sun.glass.ui.Size, java.nio.ByteBuffer
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.
