NSPopUpButtonCell Bindings
Availability Bindings
editable
A multiple-value binding that determines if the NSPopUpButtonCell
is editable in the user interface.
When editable
is bound, a new binding, editable2
, is exposed and can be bound. Binding to editable2
causes editable3
to be exposed, and so on.
The contents of the NSPopUpButtonCell
are editable if a logical AND operation on all the editable
bindings results in a Boolean value of YES
.
enabled
A multiple-value binding that determines if the NSPopUpButtonCell
is enabled in the user interface.
When enabled
is bound, a new binding, enabled2
, is exposed and can be bound. Binding to enabled2
causes enabled3
to be exposed, and so on.
The NSPopUpButtonCell
is enabled if a logical AND operation on all the enabled
bindings results in a Boolean value of YES
.
Font Bindings
font
An NSFont used to display the NSPopUpButtonCell
.
If font
is bound, all other Font category bindings are disabled.
fontBold
A Boolean value that determines if the NSFont used to display the NSPopUpButtonCell
is bold. If fontBold
evaluates to YES
, the bold attribute is added to the font.
If fontBold
is bound, the font
and fontName
bindings are disabled.
fontFamilyName
An NSString that specifies the family name of the NSFont used to display the contents of the NSPopUpButtonCell
.
If fontFamilyName
is bound to a key, the font

bindings are disabled.
fontItalic
A Boolean value that determines if the NSFont used to display the NSPopUpButtonCell
is italic. If fontItalic
evaluates to YES
, the italic attribute is added to the font.
If fontItalic
is bound, the font
and fontName
bindings are disabled.
fontName
An NSString that specifies the full name of the NSFont that is used to display the contents of the NSPopUpButtonCell
