Cocoa doesn't have combo boxes in the sense that other systems do. NSPopUpButton is not editable and technically behaves like a menu on a menubar. NSComboBox is editable and is the more traditional combo box, but the edit field and list are even more separated than they are on other platforms.
|
|
|
|
Unfortunately, their default internal storage mechanisms exhibit the automatic selection behavior I DON'T want, so we're going to have to do that ourselves.
|
|
|
|
The NSArrayController we use in our Listboxes already behaves the way we want. Consequently, you'll notice a bunch of functions here call functions in listbox_darwin.m. How convenient =P (TODO separate into objc_darwin.m?)
|
|
|
|
TODO should we use NSComboBox's dataSource feature?
