All you should need to do is have a single tools window open
and then close it via the window manager. The tool window
must be the very last window on the screen, if you also have
a symbol browser open it will not be triggered. It happens
when the windows_close method in multiview.tcl sees only
one window and calls file_close_project. Also, this only
happens with the CVS version of itk in sources so if you
are building with an older release branch it will not show up.
An even more simple test case for the itk::Toplevel class
is included below. Before the patch, this test will fail
because the button put into the external -container
window would not get deleted when the megawidget
is destroyed.
cheers
Mo
test toplevel-1.8 {when a mega-widget object is deleted, its window and any
components are destroyed (even if in another window) } {
itcl::class ButtonTop {
inherit itk::Toplevel
constructor {args} {
eval itk_initialize $args
itk_component add button {
button $itk_option(-container).b -text Button
} {}
pack $itk_component(button)
}
itk_option define -container container Container {}
}
toplevel .t1
ButtonTop .t2 -container .t1
set button [.t2 component button]
itcl::delete object .t2
set result [list $button [winfo exists $button]]
itcl::delete class ButtonTop
set result
} {.t1.b 0}
