I’m new to the monetary so please forgive any unintentional broken rules.
I am working on a graphical interface that will be used to speed up data
retrieval from a remote server @ my workplace. My problem is not life or
death I’ve already got it working with a separate button, but I’d like to
be able to bind the delete button to delete unwanted entries from a scrolled
listbox, which I have working the only problem is I can’t get the right
widget to take focus on a button click. The current code makes the listbox
take focus but the button bind won’t work. However, if I tab from the entry
widget to the frame that contains the scolled widget the button bind works
flawlessly. Is there some way I can bind to <ButtonRelease-1> to focus on
the Tk::Frame that contains the widget?

$lstbox->Subwidget("xscrollbar")->configure(-background=>'#666666' );
$lstbox->Subwidget("yscrollbar")->configure(-background=>'#666666' );
$lstbox->bind( '<ButtonRelease-1>' =>\sub{ $lstbox->focus});
$lstbox->bind($lstbox, '<Delete>' =>\&Deltxt );
