I'm trying to create a SIMBL plugin for Finder to add icon overlay over some files.

I have this code:

@implementation NSObject (FAIconOverlay)

- (void)FAIconOverlay_TIconAndTextCell_drawIconWithFrame:(struct CGRect)arg1
{
    [self FAIconOverlay_TIconAndTextCell_drawIconWithFrame:arg1];

    if (![self respondsToSelector:@selector(node)]) {
        return;
    }

    NSLog(@"%@", [[[NSClassFromString(@"FINode") nodeWithFENode:[(TNodeIconAndNameCell *)self node]] fullPath] lastPathComponent]);

    // Draw the icon overlay
}

- (void)FAIconOverlay_TDesktopIcon_drawIconInContext:(struct CGContext *)arg1
{    
    [self FAIconOverlay_TDesktopIcon_drawIconInContext:arg1];
}

@end

I can draw the icon overlay but, when I try to get the path of the file I get a "Use of undeclared identifier TNodeIconAndNameCell". Looking this link < How to Write OS X Finder plugin > I see that is neccessary to generate a Finder.h file...

My question is: How to generate this file?? I tried running "class-dump -H Finder.app" but I get too more compiling errors

Thank you very much!
