I have a situation where a user might have a great many information windows
open at the same time (like the situation in Finder where you can click on a
file and select 'Get Info' ad infinitum.)
In order handle this situation, and so that I can still update each Window
individually, I decided to store the information window classes in an
NSDictionary so that I can fiddle with them individually (and release them
individually, obviously).
This seems to work quite well - except that I can't seem to access public
member variables. The following code gives the error 'No member named
'infoWindow' in 'struct objc_object'
NSEnumerator *e = [connectedDevices objectEnumerator];
id device;
while (device = [e nextObject])
{
if ([[device objectForKey:@"LocationID"] isEqualToNumber:[sender
representedObject]])
{
[device setObject:[[DisplayInformation alloc]
initWithDictionary:device] forKey:@"InformationWindowRef"];
[[device objectForKey:@"InformationWindowRef"] showWindow:self];
Error Here --->[[device objectForKey:@"InformationWindowRef"]->infoWindow
cascadeTopLeftFromPoint:NSMakePoint(20,20)];
}
}
So I have a few questions:
1. Am I approaching this problem correctly? After all, just because something
(mostly) works, it doesn't mean that it is the right, or efficient, way to do
things.
2. If my plan isn't utter lunacy, how do I get to the member variable?
3. If my plan is lunacy, or if there's a better more efficient solution, what
is it?
