Hi Ken,
Weird behaviour of a "main window" when a modal dialog is displayed is
pretty normal I think. Just a drawback of modal dialogs.

Hi Jimmy,
Thanks for the note!
I was thinking more about this last night - the app is a legacy thing
I've taken over, where the modal selection dialog is quite a
heavy-weight entity - it captures about the same amount of real estate
as the underlying application itself, with a dozen or more controls on
it, and the user may be fooling around with it for 4 or 5 minutes at a
stretch. We've concluded that it should really just present as a
separate page on the app, rather than as a modal dialog, and probably
next release we'll be moving toward that; it solves a stack of other
interesting problems as well.
For the time being, we are trying to get to a point where someone may
have not finished messing with the selection dialog, and wants to just
minimize the whole thing (selection and main app window) in order to
move to another app. The 'other app' may be another copy of this one,
just running on a different data store, thus the need to get rid of
(minimize completely) the 1st copy to avoid confusion! Obviously, when
we move to a single window design this problem goes away; right now
just trying to get the two windows in the app (if the selection dialog
is active) to act "in unison".
In answer to your question, without any event handlers in place, I can
minimize the selection dialog using the standard Windows "_" control,
which leaves the main app window in view, but totally disabled -
minimize, exit, etc. are disabled along with any of the app's
controls. Taskbar still had two icons, one for the dialog and one for
the main app, and I could restore the dialog and continue.
When I added in an event handler, both the selection and main app
windows disappeared, with the modal dialog apparently completely gone
(no taskbar icon any more) and the underlying app still waiting for
it, so it's taksbar icon was completely disabled, unable to restore,
cancel, anything.
Hope to get this to work in some fashion, but as I said, I'm going to
be turning this into a separate page for a single app at some point so
I may find some interim not-quite-what-they-want solution if this
turns out to be too much effort to get going.

Can you manually minimize the modal dialog and then minimize the
main window at all? The definition of a modal window is that you
must interact with it first before returning to the main
application, so I wouldn’t think that you could minimize both, and
then somehow ever get back to the parent window.
Also, you should try reproducing this with C# or VB; this sounds
like it has nothing to do with IronPython, just an issue with
using the API.

Hi,
I have a WPF app and I'm trying to mess with WindowState. I have
two windows, a modal selection dialog, and a main window. If I
bring up the selection dialog with the main window in background,
and minimize the selection dialog, it leaves the main window
visible but you can't interact with it. So far, normal.
If I make a selection, the select dialog closes leaving the main
window, and I can minimize the main window using the standard
windows controls, and restore it from the taskbar. OK so far.
However, I want to get it working like this: if I minimize the
selection dialog, I'd like to minimize the main window also. So, I
added an event listener on StateChanged, something like:
def state_changed(...):
if self._w.WindowState == WindowState.Minimized:
main_window.WindowState = WindowState.Minimized
This captures the minimize event, both the selection dialog and
main window minimize, BUT now I can't right-or-left-click on the
minimized app to get it to restore, and have to kill the app using
task manager. Also, it appears that instead of having two windows
represented on the taskbar, only the main window is left - even
though I should still have both the select dialog and the main
window minimized.
Is there some magic state I need to set in the main window to be
able to have it restore again? Why should it make a difference
whether the minimize is done by the main window 'min' button, or
by setting its WindowState?
