I want to us e the whole window of my application as the drop target
for files dragged onto it from the Finder but there are a couple of
things I can't seem to figure out:
I would like to show some sort of visual feedback. I tried subclassing
the content view of the window thinking it would automatically hilite,
but I can't get it to. Note I set focus ring to default in IB for
this. Also the drag icon doesn't update to show a '+' symbol.
After I get the file what should I do to make sure the document is
still set up correctly. I currently call my documents readFromURL:
ofType: error: method to load the file but I am not sure if that is
correct as calling
synchronizeWindowTitleWithDocumentName afterwards doesn't change the
title of the window to the new file name.
Note that I would like to reuse the document and window, not create a
new one. This is what I am currently doing inside my
NSWindowController subclass:
- (void)awakeFromNib{
[[self window] registerForDraggedTypes:[NSArray
arrayWithObjects:NSURLPboardType, nil]];
}
- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender {
return NSDragOperationGeneric;
}
- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender{
NSPasteboard *pboard = [sender draggingPasteboard];
if ( not [[pboard types] containsObject:NSURLPboardType] )
return NO;
if( not [[self document] readFromURL:[NSURL URLFromPasteboard:pboard]
ofType:@"AVR Hex File" error:nil])
return NO;
[self synchronizeWindowTitleWithDocumentName];
return YES;
}
thanks for any help!
Peter
