A "return -1;" , actually closes all the windows and exits the
program which is not quite what I had in mind! It would be nice if it
was that simple though!
Thanks for all the replies so far.

I've got you covered. Here is a better way to approach this.
First off, you don't want to keep a single global-variable results
window. That gets tricky when you want to have more than one of them.
Instead, I would keep a global array called maybe @ResultsWindow (to
keep with your naming scheme).
When you want to create a new Results Window, you would do this:
push(@ResultsWindow, new GUI::Window( ....... );
Use some ideas from Jeremy White's code as for deciding what to name
each window.
When you're ready to close a window, the best thing I've found is to
make a _Terminate event, and if you want a button, have the button call
the _Terminate event, like so:
sub Window_Terminate {
# Free up any resources, disconnect sockets, etc
# ...
# ...
return -1;
}
sub WindowCloseButton_Click {
return Window_Terminate();
}
The "return -1" tells Win32::GUI to delete the widget that initiated the
subroutine call, in this case it will free the Window's resources and
delete the Windows GUI object.
I haven't tried it, but you might even be able to name the windows the
same thing, so that the _Terminate and _Click events can be hardcoded
into your source, instead of eval'ed in.
Sorry I don't have time to get more detailed on this, perhaps I'll send
a complete example in a couple days.

windows
Well basically the MainWindow has a button to create a results
window and by design I want it to be able to create more than one window
with results (for camparison etc).
The new results window is created like this -
$ResultsWindow = new GUI::Window(
-title => "Results",
-left => 400,
-top => 100,
-width => 185,
-height => 360,
-style => WS_MINIMIZEBOX | WS_CAPTION | WS_SYSMENU ,
-name => "ResultsWin",
);
I then add a text area and a 'Close' button to this window.
The close button is added like this -
$ResultsWindow->AddButton(
-name => "Close",
-text => "Close",
-left => 5,
-top => 5,
-tip => "Click here to close the results view",
-cancel => 1,
);
The subroutine for the click event looks like this -
sub Close_Click {
$ResultsWindow->Hide();
}
The reason I use hide if because I dont know of a better way of
getting rid of Windows?!
Clicking the close button then closes the last window created.
Help?

Can we get some sample code to see how you're handling
the window creation / closing?

Subject: [perl-win32-gui-users] Keeping track of
child windows
All,
I have a gui window that can spawn multiple
child windows, each with its own 'Close' button on it. The close button
works fine if there is only one child window but fails to work if there
are more than one. I understand why this is happening but cannot think
of a good way around it!
Anyone have any ideas or can point out the
obvious?
Cheers,
Darin

There may be a better way, but here are
two possible ways:
### THIS WILL BRING UP THE SAME PRINT
WINDOW AS USED BY WEB BROWSER
$dll =
"$ENV{'WINDIR'}/System32/mshtml.dll";
system("rundll32.exe $dll,PrintHTML
$file");
-OR-
### THIS MAY OR MAY NOT GIVE THE BEST
RESULTS
system("copy $file
\\\\ServerName\\PrinterName");
Good luck.

All,
I have a Perl application that uses
Win32::GUI to provide a nice front end for a database, what I would
really like to do is provide a print feature with the ability to print
to a network printer through the gui. Does anyone know of any way to do
this?
Cheers,
