Ok, here's what I have:
my $toolbar = Gtk2::Toolbar->new;
(...several Gtk2::ToolButton->new_from_stock('gtk-stuff') here...)
my $new_button = Gtk2::ToolButton->new_from_stock('gtk-foo') # to be added later
later in code:
if($blah) {
$toolbar->insert($new_button, -1); # <- this part seems to work
} elsif($foo) {
$toolbar->remove($new_button);
}
These are the errors that are showing during this process:
Gtk-CRITICAL **: gtk_toolbar_remove: assertion `content_to_remove !=
NULL' failed at ./stuff line 1064.
Gtk-WARNING **: Can't set a parent on widget which has a parent
Gtk-ERROR **: file gtkcontainer.c: line 2447
(gtk_container_propagate_expose): assertion failed: (child->parent ==
GTK_WIDGET (container)) at ./stuff line 289.
Aborted
Any hints?
I haven't attempted Gtk2::UIManager yet - what I'm attempting here
seems simple and I'm trying not to have to rewrite lots of code... :)
