[MSEide-MSEgui-talk] mseide-msegui - grid woes (msefiledialogx)

[Sieghard <s_...@ar...>]

Hello Fred,

just to let you know that I'm _STILL_ at this beast of a file dialog, here's
a short report of the current situation - not progress, because there IS NO
progress yet...
You might remember that I was fiddling with the "verbose" file list view
(list_log) to allow for multiple file selections. Well, I'm still.
But I think I found a - the? - reason why this doesn't seem to work in any
case - it might indeed NOT WORK IN ANY CASE. Deep in the grid unit's code,
there are handlers for anything and all one might be attempting to do with
the data, and they preempt any attempts of user code executing later and
often even before to do somethimg else. And even worse, most of the call
back vectors don't seem to be called of this, at least most of the time. It
seems that's why the "onselectionchanged" call back never executes, and
except for the "oncellevent", most others as well.
I even failed having it controlled by keys, as e.g. the return key ALWAYS
somehow activates the current entry and terminates the dialog. This happens
even if handled by the "oncellevent" call back, because there's no means to
signal it's already done. The calling code bluntly carries on and does what
it "always does".
So I'm about to give up on this now, though I think this was a really nice
piece of code and very useful for many tasks. Most of the other file
dialogs I had to use are clumsy, clunky and overburdened on the one hand
or overly restricted on the other.

Anyway, have a nice time, and keep on computing happily!
