java - What role does optionType play in a JOptionPane OptionsDialog? -


note: please pay attention fact options dialog here, not confirm dialog. makes difference in i'm asking , how swing behaves!

i looked @ code example of option dialog in action, confused 1 thing:

if supplying dialog options in options parameter, of use/role/significance optiontype parameter?

according javadocs you're options are:

  • default_option
  • yes_no_option
  • yes_no_cancel_option; or
  • ok_cancel_option

how these different options affect resultant dialog, or swing ignore them?!? in advance!

the optiontype parameter defines amongst options user have choose. if use yes_no_cancel_option, display 3 buttons, 1 each option:

  • yes
  • no
  • cancel

enter image description here

the same goes possible optiontype values.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
