[Pythoncard-users] Live property editor

[Neil H. <nho...@bi...>]

   Something I like to see in user interfaces is live updating where
attributes are changed as the user fiddles with them rather than requiring
pressing an "Apply" button. To this end, the property editor can be changed
to apply changes to the text areas and check boxes immediately by adding
this just after the EVT_BUTTON section of debug.py:

        EVT_TEXT(self, self.wTextArea.GetId(), self.onSelectUpdate)
        EVT_TEXT(self, self.wField.GetId(), self.onSelectUpdate)
        EVT_CHECKBOX(self, self.wChecked.GetId(), self.onSelectUpdate)

   To make the font and colour dialogs take immediate effect, add
            self.onSelectUpdate(event)
    as the last line of onSelectColor and onSelectFont inside the if
dlg.accepted() condition.

   A problem with this is that some settings such as the file names used
within image controls will cause error messages with partially updated file
names. Mostly, these should be changed to just silently handle failure or
perhaps have a status area indicator that the field is invalid. For file
names, the file open dialog should ensure that only valid file names are
applied and this has the advantage of being able to select files rather than
just type their names.

   I haven't changed CVS as there may be other opinions and this change
could be made an option instead of always being on.
