View file @ 52ba8bfb
2004-08-29 Karl Runge <runge@karlrunge.com>
* remove old mouse patch code, now use rfbSetCursor (+ workarounds)
* changed cursor shape options (no more -mouse, ...) to '-cursor mode'
where 'mode' can be empty "X", "some", or "most". "some" adds
heuristics for two more cursors.
* -nocursorshape added.
* ifdef checks for XSHM and XTEST. Add *_wr wrappers as well.
* -vncconnect is now the default.

-xwarppointer Move the pointer with XWarpPointer() instead of XTEST

-cursor [mode] Sets how the pointer cursor shape (little icon at the
-nocursor mouse pointer) should be handled. The "mode" string
is optional and is described below. The default
is to show some sort of cursor shape(s). How this
is done depends on the VNC viewer and the X server.
Use -nocursor to disable cursor shapes completely.
Some VNC viewers support the TightVNC CursorPosUpdates
and CursorShapeUpdates extensions (cuts down on
network traffic by not having to send the cursor image
every time the pointer is moved), in which case these
extensions are used (see -nocursorshape and -nocursorpos
below). For other viewers the cursor shape is written
directly to the framebuffer every time the pointer is
moved or changed and gets sent along with the other
framebuffer updates. In this case, there will be
some lag between the vnc viewer pointer and the remote
cursor position.
If the X display supports retrieving the cursor shape
information from the X server, then the default
is to use that mode. On Solaris this requires
the SUN_OVL extension and the -overlay option to be
supplied. (see also the -overlay_nomouse option). (Soon)
on XFree86/Xorg the XFIXES extension is required.
Either can be disabled with -nocursor, and also some
values of the "mode" option below.
The "mode" string can be used to fine-tune the
displaying of cursor shapes. It can be used the
following ways:
"-cursor X" - when the cursor appears to be on the
root window, draw the familiar X shape. Some desktops
such as GNOME cover up the root window completely,
and so this will not work, try "X1", etc, to try to
shift the tree depth. On high latency links or slow
machines there will be a time lag between expected and
the actual cursor shape.
"-cursor some" - like "X" but use additional
heuristics to try to guess if the window should have
a windowmanager-like resizer cursor or a text input
I-beam cursor. This is a complete hack, but may be
useful in some situations because it provides a little
more feedback about the cursor shape.
"-cursor most" - try to show as many cursors as
possible. Often this will only be the same as "some".
On Solaris if XFIXES is not available, -overlay mode
will be used.
-nocursorshape Do not use the TightVNC CursorShapeUpdates extension
even if clients support it. See -cursor above.
-cursorpos Option -cursorpos enables sending the X cursor position
-nocursorpos back to all vnc clients that support the TightVNC
CursorPosUpdates extension. Default: -cursorpos
CursorPosUpdates extension. Other clients will be able
to see the pointer motions. Default: -cursorpos
-xwarppointer Move the pointer with XWarpPointer(3X) instead of XTEST

motion behaves incorrectly, e.g. on touchscreens or
other non-standard setups. Also sometimes needed on

.IP
Sets how the pointer cursor shape (little icon at the
mouse pointer) should be handled. The "mode" string
is optional and is described below. The default
is to show some sort of cursor shape(s). How this
is done depends on the VNC viewer and the X server.
Use \fB-nocursor\fR to disable cursor shapes completely.
.IP
Some VNC viewers support the TightVNC CursorPosUpdates
and CursorShapeUpdates extensions (cuts down on
network traffic by not having to send the cursor image
every time the pointer is moved), in which case these
extensions are used (see \fB-nocursorshape\fR and \fB-nocursorpos\fR
below). For other viewers the cursor shape is written
directly to the framebuffer every time the pointer is
moved or changed and gets sent along with the other
framebuffer updates. In this case, there will be
some lag between the vnc viewer pointer and the remote
cursor position.
.IP
If the X display supports retrieving the cursor shape
information from the X server, then the default
is to use that mode. On Solaris this requires
the SUN_OVL extension and the \fB-overlay\fR option to be
supplied. (see also the \fB-overlay_nomouse\fR option). (Soon)
on XFree86/Xorg the XFIXES extension is required.
Either can be disabled with \fB-nocursor,\fR and also some
values of the "mode" option below.
.IP
The "mode" string can be used to fine-tune the
displaying of cursor shapes. It can be used the
following ways:
.IP
"-cursor X" - when the cursor appears to be on the
root window, draw the familiar X shape. Some desktops
such as GNOME cover up the root window completely,
and so this will not work, try "X1", etc, to try to
shift the tree depth. On high latency links or slow
machines there will be a time lag between expected and
the actual cursor shape.
.IP
"-cursor some" - like "X" but use additional
heuristics to try to guess if the window should have
a windowmanager-like resizer cursor or a text input
I-beam cursor. This is a complete hack, but may be
useful in some situations because it provides a little
more feedback about the cursor shape.
.IP
"-cursor most" - try to show as many cursors as
possible. Often this will only be the same as "some".
On Solaris if XFIXES is not available, \fB-overlay\fR mode
will be used.
.PP
