问题
I am having a problem on what to use and what to code if I want my combo box be generated once the user type a key...
like:
once i pressed letter "A" from keyboard inside the combo box, all items starting from letter "A" will show up from the drop down list.
How can I code this when:
items from the combo box came from my database and it's default value is the first item stored on my database.
Actually I don't have any idea how to code it. All I have was a template from JFrame.
Items from database were just drag to combo box and it automatically generate a class.
Please Help. Thanks in advance ^_^
