Jay: I hope I am on the mark here with what you are trying to
achieve.... I have just constructed a rather tiny app that displays a
custom image in the Dock. This custom view is shown in the dock for
the app itself when running (not just when minimized). The app icon
is *not* shown because I have set a custom content view for the dock
tile (nor would any badge be displayed, if set).
The custom view is a class named DockTileView. When the app starts up,
I create an instance of this class, and set it as the dockTile's
contentView:
DockTileView *myDockTileView = [[[DockTileView alloc] init]
autorelease];
[[NSApp dockTile] setContentView: myDockTileView];
[[NSApp dockTile] display]; // cause the dock tile have the view draw
itself
The DockTileView is a trivial subclass of NSView:
@interface DockTileView : NSView {
}
@end
For this proof-of-concept app, the DockTileView just displays some
text in the overridden -drawRect method:
@implementation DockTileView
- (void) drawRect:(NSRect)rect
{
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
[NSColor orangeColor], NSForegroundColorAttributeName,
[NSFont systemFontOfSize:32], NSFontAttributeName,
nil];
NSString *text = @"Custom\nDock\nTile";
NSMutableAttributedString *as = [[NSMutableAttributedString alloc]
initWithString:text attributes:attributes];
[as drawInRect:rect];
}
@end
Of course, you can have your custom view draw whatever you'd like (in
a 128 x 128 frame).
If the appearance of the view needs to change due to underlying
changes in teh state of your app, just issue the -display message to
the dockTile:
[NSApp dockTile] display];
and the contentView object's -drawRect will be called.
