in reply to Tk::BrowseEntry listbox scrollbar with Mousewheel on Windows

G'day perltux,

"... but despite trying various subwidget targets ..."

I often find checking the source code provides answers for this type of issue. In this case, &SetBindings, in http://cpansearch.perl.org/src/SREZIC/Tk-804.033/Tixish/BrowseEntry.pm, has: 

    ...
    # bindings for listbox
    my $sl = $w->Subwidget('slistbox');
    my $l = $sl->Subwidget('listbox');
    $l->bind(...

I don't have MSWin to check your specific OS problem.

The DESCRIPTION of Tk::BrowseEntry starts:

"BrowseEntry is a poor man's ComboBox."

Instead of rolling your own bindings, and potentially other functionality, for Tk::BrowseEntry, perhaps consider using one of the more feature-rich widgets, such as Tk::JBrowseEntry or Tk::JComboBox.

    Yes, I did go through the source code of BrowseEntry.pm, that's how I found those various subwidgets to try (see the commented out lines in my example source code) but none of them seem to work when it comes to the mousewheel binding of the pop-up listbox on Windows.

    Tk::JBrowseEntry or Tk::JComboBox were considered in the past but they had other shortcomings that made them unsuitable and which made me choose BrowseEntry.
