Subject: More Java viewer clipboard handler fixes
X-Git-Tag: v1.4.0~10
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=1e6cb40a1d33e50a9d3c118689284c593e8fcbe7;p=tigervnc.git

More Java viewer clipboard handler fixes

* Override TransferHandler.exportToClipboard method to ensure that
  serverCutText updates get sent to the system clipboard.  This
  wasn't always happening when relying on the super class' paste()
  method alone.
* Removed some unnecessary setText() statements and one check for
  whether sending client cut text is enabled.

(cherry picked from commit 4f95737b72a516f0ca2ffdd1d299b7469ea90962)
