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 @1Silas - 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 {}
J. 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." [L1 ]
