如何将JButton与JComboBox结合在一起？

Question

How do I "combine" JButton with JComboBox and place it on a JToolbar, as shown in this image: ?

Answer 1

您将要使用我怀疑的自定义渲染器 ，并使其显示可单击的按钮（附带适当的操作，等等）。

Answer 2

Just create regular combo box and put image as an item. I did it once. Unfortunately I do not have a source code here but as far as I remember it was not a problem. You have to implement your custom 1ListCellRenderer . Its method . Its method getListCellRendererComponent()` should return for example Label with your image.
