在Java中单击按钮时可以更改组合框值吗？

Question

By using doClick() method, the action of a button can be triggered. Is there such a way to change combobox value when a button is clicked in java? Thank You.

Answer 1

As you didn't state the graphical framework I assume you use Swing, as it contains a doClick function .

The doClick() function is only used to emulate a button click programmatically, for example in testing. This will fire all actions that are normally associated with that button, however you need to register those yourself, using a listener .
