JComboBox problem...

Mar 31, 2009 09:38:45

hey,
i'm having a problem with getting the first item in the JComboBox() being selected. i have to select another item before i'm able to select the first item and trigger it. i'm using 1.6 :

i never used JComboBox() before, so any help would be appreciated. thanks in advance.

You are facing the problem because of adding ActionListener to JComboBox. Use a ItemListener for the JComboBox. Have a look at java tutorial's JComboBox section for usage and more details. http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html

i added the following; still exhibits the same behavior. also setSelectedIndex() will not work for first item as well. any ideas?

A ItemEvent will be generated only when the selection changes. Since already the first element is being selected setSelectedIndex(0) will not raise an event. You may want to initially set the text for price label or add a first item like "Select a size" to JComboBox and don't set any initial value for price label.
Hope this helps.
