Maybe you could fake the mouse even that would normally pop it open.
Actually, after some experimentation I figured out how to do it using the accessibility API:
@interface NSComboBox (MYExpansionAPI)
@property (getter=isExpanded) BOOL expanded;
@end
@implementation NSComboBox (MYExpansionAPI)
- (BOOL) isExpanded
{
id ax = NSAccessibilityUnignoredDescendant(self);
return [[ax accessibilityAttributeValue:
NSAccessibilityExpandedAttribute] boolValue];
}
- (void) setExpanded: (BOOL)expanded
{
id ax = NSAccessibilityUnignoredDescendant(self);
[ax accessibilitySetValue: [NSNumber numberWithBool: expanded]
forAttribute: NSAccessibilityExpandedAttribute];
} @end —Jens
