public class X11

extends POSIX

Platform implementation for POSIX compliant operating systems with an X11 Server

Nested Class Summary

static class	X11.X11Picture Implements a Picture.
static class	X11.X11PixelBuffer An X11PixelBuffer is implemented as an X11 pixmap.
static class	X11.X11Surface Implements a Surface as an X11 Window

Field Summary

static java.lang.String	clipboard our local (in-process) copy of the clipboard
static Semaphore	waiting_for_selection_event When the user reads from the clipboard, the main thread blocks on this semaphore until we get an X11 SelectionNotify.
static java.util.Hashtable	windowToSurfaceMap map from Window's (casted to jlong, wrapped in java.lang.Long) to X11Surface objects

Method Summary

protected Picture	_createPicture(int[] data, int w, int h)
protected PixelBuffer	_createPixelBuffer(int w, int h, Surface owner)
protected Surface	_createSurface(Box b, boolean framed) this method invokes the platform _createSurface() method and then enforces a few post-call invariants

protected java.lang.String	_getClipBoard()
protected int	_getScreenHeight()
protected int	_getScreenWidth()
protected boolean	_needsAutoClick()
protected boolean	_needsAutoDoubleClick()
protected void	_setClipBoard(java.lang.String s)
protected void	eventThread()
void	init() this initializes the platform; code in here can invoke methods on Platform since Platform.platform has already been set

Field Detail

waiting_for_selection_event

public static Semaphore waiting_for_selection_event

When the user reads from the clipboard, the main thread blocks on this semaphore until we get an X11 SelectionNotify. Crude, but effective. We know that only one thread will ever block on this, since only one thread can ever be running JavaScript.

clipboard

public static java.lang.String clipboard

our local (in-process) copy of the clipboard

windowToSurfaceMap

public static java.util.Hashtable windowToSurfaceMap

map from Window's (casted to jlong, wrapped in java.lang.Long) to X11Surface objects
