[udig-devel] Invalidate a draw command
|
Please invalidate a the draw command used to draw the lin in response
to tool feedback.
The draw commands are kept in a queue and always drawn; if you set the
draw command to invald (ie command.setActive( false) ) it will be
removed from the queue.
See http://udig.refractions.net/confluence/display/DEV/3+Draw+Command
I have added your question to the page to help the next person
