Entry Widget (copy and paste issue)

rookie_monk has asked for the wisdom of the Perl Monks concerning the following question:

I am not sure how to resolve the issue when you copy and paste into an entry widget. When you selected the existing text in the entry widget and do a paste (over it), it adds the text you copy and paste it to the existing text rather than overwrite the selected existing text. I do not see any Entry options in the documentation which will allow me to do this. Below is the code I have that sets up the entry widget:

my $ent3 = $frm_chapter -> Entry(-width=>3, 
            -insertwidth => 3,
             -exportselection =>1) -> 
            pack(-side => 'left',
             -expand => 1);

# I also know that there are methods such as 
# $entry->selectionClear( );
# $entry->delete( );
# but how do I incorporate it to work when I paste?

Thanks in advance for your help. -Paul

Are you talking about Tk::Entry? See http://search.cpan.org/dist/Tk/pod/Entry.pod#DEFAULT_BINDINGS The F18 key (labelled Paste on many Sun workstations) or Control-y inserts the contents of the clipboard at the position of the insertion cursor. On my win32 machine, ctrl-y doesn't work, but ctrl-v does and behaves the same. If you want to change the behaviour, you will have to override the binding, eg `$ent3->bind('<<Paste>>', sub { .... } );` [download]	[reply] [d/l]

You may be interested in virtual events and real events with eventGenerate seem to not work the same... Also: `#!/usr/bin/perl use Tk; $top = new MainWindow; $top->eventAdd(qw[<<Copy>> <Key-F4>]); $top->eventAdd(qw[<<Paste>> <Key-F5>]); $top->Text->pack; MainLoop; __END__` [download] I'm not really a human, but I play one on earth.

I may be communicating my thoughts incorrectly. The copy and paste works. The problem is when I paste it, if there is already text in the entry(text box), even though I have the text in the entry(text box) highlighted, it doe not over-write it but instead it appends to it. For example, lets say I copied the text "TEXT" and I pasted it into a entry(text box) which already contains the text "NEW". The new text in the entry(text box) is now "NEWTEXT" rather than just "TEXT".	[reply]

I understood. You need to bind a sub to Paste that will overwrite the hilighted text, because the default binding will not do that, not under any circumstance	[reply]
