Since self is the application object change it to
OSStatis HotKeyHander(...)
{
[anObject aMethod];
[NSApp myCocoaMethod:YES];
}

I have a hotkey handler that needs to call a method using "self" but
it causes a compile error. Elsewhere in my program I'm using "self"
without error. The hotkey handler is a C routine because that's what
I need in order to register it as the handler. Here's the outline:
#import <Cocoa/Cocoa.h>
#import <Carbon/Carbon.h>
@implementation NSApplication (mainline)
OSStatus HotKeyHandler(...)
{
[anObject aMethod]; // works for Foundation, et al
[self myCocoaMethod:YES]; // <--- causes "self" undeclared error
{
-(void) myCocoaMethod:(BOOL)flag
{
// never get here
}
@end
As a workaround, I can make it work by saving the value of "self" in
another variable during initialization and use that later in my
handler. E.g,:
NSApplication *mySelf;
...
{
...
mySelf = self;
}
I want to understand why the compiler is complaining. What must I to
do to get "self" to work in HotKeyHandler()?
