// Implementation of native dialogs for OSX.  These are temporary standins
// till we can fix the underlying bug in WebKit that's preventing us from
// using HTML Dialogs like the other Gears ports.

// Since the dialogs are so similar, we define a BaseNativeDialog that 
// implements nearly all of the functionality and draws the dialog components.
// Terminology used for dialog componets:
// gears_imageview_ - The image at the top left of the permission and location
// dialogs, this is blank in the case of the shortcut dialog.
// site_imageview_ - The site-specific icon portion of the dialogs.
// dialog_text_    - The central text area used to display the origin name
// and description text, we use the basic HTML parsing capabilities of the
// NSAttributedString class to display this.
//
// NativePermissionsDialog & NativeShortcutsDialog derive from the base class,
// they only add argument parsing and generation of the dialog_text html.

#import <Cocoa/Cocoa.h>
#import "gears/base/common/string16.h"

// This is the function that interfaces the native dialogs with the outside
// world.
