Any example about custom NSComboBox?

由 微笑、不失礼 提交于 2019-11-28 04:43:01
问题 I am asked to implement an combo box like this: It is clear that this is quite different from NSComboBox : <1> The button of beside the text field should be customized <2> This is much more important: there is an additional "cross" (which is a button indicating "delete" action) in each of the combo item.
