NSPopUpButton Bindings
Availability Bindings
enabled
A multiple-value binding that determines if the NSPopUpButton
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 NSPopUpButton
is enabled if a logical AND operation on all the enabled
bindings results in a Boolean value of YES
.
hidden
A multiple-value binding that determines if the NSPopUpButton
is displayed in the user interface.
When hidden
is bound, a new binding, hidden2
, is exposed and can be bound. Binding to hidden2
causes hidden3
to be exposed, and so on.
The NSPopUpButton
is hidden if a logical OR operation on all the hidden
bindings results in a Boolean value of YES
.
Font Bindings
font
An NSFont used to display the NSPopUpButton
.
If font
is bound, all other Font category bindings are disabled.
fontBold
A Boolean value that determines if the NSFont used to display the NSPopUpButton
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 NSPopUpButton
.
If fontFamilyName

bindings are disabled.
