DSFComboButton

A drop-in NSComboButton replacement control with pre macOS 13 support.

For when you want to adopt NSComboButton but have to maintain compatibility back to 10.13.

Features

DSFComboButton attempts to match the NSComboButton control API as closely as possible. The programmatic interface is almost identical, however (unfortunately) Interface Builder support in a custom control is very limited so I’ve done as best I can.

Split style

• Click on the leading side of the button to perform a ‘default’ action
• Click on the down arrow to present a menu

Unified style

• Click on the button to perform a ‘default’ action
• Click and hold to present a menu

Styles
