help with textbox and Return key...

[ee1]

Hi all,
i have a text box, using for entering search text,
nowthe search proc works only when i push the "find" button.
i want it to work after pressing the Return key when i am in the textbox.
this is the code:
frame .bottom
label .bottom.search -text "search:"
entry .bottom.ent -textvariable find -relief sunken -bg white -width 60
button .bottom.but -text find -command "search proc"


thanks.

bind .bottom_ent <Return> {search_proc}

Also try adding this to .bottom.ent

-validate key \
-validatecommand {if {[string length %P] < 3} {return 1}
search_proc %P; return 1}

If you type more than two characters into the entry field then it will run the search proc using the characters entered. Of course your search proc needs to be in the form

proc search_proc {find} {
}
