Alternative startup for application
Hi, I would like to have an application I am working on to be able to start up in the normal way from the finder, but also have an alternative startup that users can access in some way, where I will display a panel that most users wouldn't normally want to see. Issues I am having with this are: 1. I'm not sure what keyboard or mouse options could be used for this, since all the character keys change the selection in Finder, and all the normal modifier keys are used for special functions. So first question is how I can differentiate this special mode open from a normal open? 2. If the application is started up in this special way, how would I be able to detect it, seeing as there is no current event to query? ...or is there some other mechanism I could be using instead?

This works in Snow Leopard and Leopard (I believe).
- (void)applicationDidFinishLaunching:(NSNotification *)notif {
CGEventRef event = CGEventCreate(NULL);
CGEventFlags modifiers = CGEventGetFlags(event);
CFRelease(event);
CGEventFlags flags = (kCGEventFlagMaskAlternate | kCGEventFlagMaskControl);
if ((modifiers flags) == flags)
[self doSomethingSpecial];
}

Re: Alternative startup for application
Excellent, I like the new way of doing it using NSEvent directly, but I do need
to support Leopard.
If you launch from Finder holding the Option key, Finder closes the window you
launched from, but I can tell people to put it in the dock and launch from
there to avoid that.
Here's what I'm doing, which appears to work fine (haven't tested on Leopard
yet, but have tested the CG code in Snow Leopard and that worked).:
- (void)applicationWillFinishLaunching:(NSNotification*)aNotification {
if (floor(NSAppKitVersionNumber) NSAppKitVersionNumber10_5) {
if (([NSEvent modifierFlags]
NSDeviceIndependentModifierFlagsMask) == NSAlternateKeyMask) {
[self doSpecialStartup];
}
} else {
CGEventRef event = CGEventCreate(NULL);
CGEventFlags modifiers = CGEventGetFlags(event);
CFRelease(event);
if ((modifiers kCGEventFlagMaskAlternate) ==
kCGEventFlagMaskAlternate) {
[self doSpecialStartup];
}
}
...
}
Thanks again for the help.
Gideon
The modern (Snow Leopard) equivalent for finding the state of the Option
key would be +[NSEvent modifierFlags].

Re: Alternative startup for application
That's the instance method. New in 10.6 is the class method of the same name, which is what I need in this case, since I don't have an event to work with.
