[REBOL] Problem with dirty?
From: reboler::programmer::net at: 10-Apr-2002 13:28
The View Documentation says the following:
dirty? A LOGIC flag that indicates that the text of the face has been modified. Whenever
editing is performed upon a text face, this flag will be set to TRUE.
I read last years thread about "Bug in Area", and got some tantalizing clues but...
I have a 'box (view-box) with one of two panes (picture-pane or text-pane).
'text-pane is an 'area, modified with flags: [field].
When I do the following ...
view-box/pane: text-pane
I edit the text in text-pane
I check the state of 'dirty?
... I always get 'none
This is true for view-box/dirty?, view-box/pane/dirty?, or text-pane/dirty?.
Here is the code I check it with ...
if text-pane/dirty? [
if request {File was changed! Save it now?} [exit]
]
..., the above being part of a function. The 'request is never called, even after editing
the text in text-pane.
Does anyone have any ideas why?
Something to do with panels/panes?
Do I need to set the dirty? flag myself?
If so, what event do I need to catch? (face = text-pane event = 'down ???)
Thanks in advance for your time.
