[[insert image of the widget here?]]

[Silas] - 2005.08.25 A simple BWidget::ComboBox example:

  package require BWidget

  ComboBox .combo -values {zero one}
  pack .combo

  #changing the content of the combo
  .combo configure -values {two three}

  #return the index of the current item
  puts [.combo getvalue]

  #set a new index
  .combo setvalue @1

[Silas] - 2005.11.04 

ComboBox doesn't have any clear method. [[setvalue @-1]] doesn't work too. If you want to clear the content of the Combo, just configure its text as {}:

  .combo configure -text {}

[Jason Tang] provides a patch which "adds a          
new feature, '-autopost', that automatically posts the combobox as the          
user is typing into the entry.  Furthermore, it will scroll the                 
drop-down to entry that most closely matches the user's input."
