[wxhaskell-users] Tree control with editable labels

[<jmv...@di...>]

Hi

=20

Could someone please point me how can I let my labels in a tree control =
to
be editable and how can I get the old and new labels to update my data?

I looked to FileBrowse example of wxHaskell and I learn lots of things =
from
there but not this one. I intended to search on the wxHaskell mailing =
list
but my internet connection stays limited during all day due to some
technical problems in the university.

=20

I would appreciate some help.

Best regards

Hi José,

I did it like this:
 
main = start gui

gui = do
  tv <- treeCtrl sw [style :~ (wxTR_EDIT_LABELS .+.)]
  set tv [ on treeEvent  := handleTreeEvent tv ]

handleTreeEvent :: TreeCtrl () -> EventTree -> IO ()
handleTreeEvent tv event =
  case event of
  TreeEndLabelEdit treeItem newLabel cancelled veto | not cancelled ->
... -- process event
  _ -> propagateEvent

Best regards,
Bernd Holzmüller
