Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: clohr (clohr) Assigned to: Nobody/Anonymous (nobody) Summary: Add a ButtonMap option to vncviewer Initial Comment: Hi, I propose to add a ButtonMap option to vncviewer to remap pointer buttons. For instance use "321" button mapping while connecting to the session of a lefthanded user. Note that another way to manage this is to reconfigure pointer on server side, e.g.: xinput --set-button-map 'Virtual core XTEST pointer' 3 2 1 However it is sometimes not desirable since XTEST may be used by plenty of tools.This may disturb the user that sits on the vncserver side.

Commander (dcommander) Date: 2012-02-07 11:47 Message: There is already a program (vncconfig) and an X11 extension (VNC) designed for this type of stuff. They are currently used to transfer the clipboard between the VNC server code and the X server, as well as to initiate reverse connections. I'm sure that the mechanism could be extended to handle button mapping changes, but I'm not volunteering. ---------------------------------------------------------------------- Comment By: clohr (clohr) Date: 2012-02-07 11:12 Message: I do agree with you. Most of the time left handed users are considered as "reversed", and righthanded users are considered as "normal" ;-) leading to funny situations... The re-mapping can be performed either by the vncviewer or either by the vncserver (or both). Unfortunately, the code of vncserver is too complicated for me. That's why I chose to patch the vncviewer (see the patch attached to my first post). However, the vncserver could automatically guess a relevant mapping, asking the X11 server what are the actual physical and logical button-mappings with something like: $ xinput -get-button-map 'Virtual core XTEST pointer' $ xmodmap -pp Unfortunately, there is no XEvent propagation when the user re-configure its mouse. The vncserver should then poll the X11 server, or plays with X11 internals tricks... Any idea? ---------------------------------------------------------------------- Comment By: D. R. Commander (dcommander) Date: 2012-02-06 12:10 Message: Speaking as a left-handed mouser, all versions of VNC (not just Tiger) have annoyed me in this respect for years. What I really want is for VNC to honor the mouse button configuration used on the server's window manager, but that's never what happens. Instead, if the server is configured for a left-handed mouse and the client is configured for a left-handed mouse, the two cancel each other out. Thus, I have to re-configure the server for a right-handed mouse, and then it works properly (but, of course, the next time I log into the server locally, I have to configure the mouse back to left-handed mode.) I think the correct behavior would be to honor the server's button order rather than the client's, but I'm not sure that that wouldn't require extending the RFB protocol. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126849&aid=3484687&group_id=254363 ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
