ok that makes sense. > I dunno know what to declare in the pasteboard when it is about NSIndexSets. > And what to do next after implementing writeItemsAtIndexes:toPasteboard:…? > Thanks so much for your help, I really appreciate it. This is not something specific to the IKImageBrowserView here so the pasteboard programming guide should help: http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/PasteboardGuide106/Introduction/Introduction.html Typically you will have to do something like this: - (NSUInteger) imageBrowser:(IKImageBrowserView *) aBrowser writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard:(NSPasteboard *)pasteboard { NSUinteger index; //instantiate an array to store paths filesArray = [NSMutableArray array]; //for each index... for(index = [itemIndexes firstIndex]; index != NSNotFound; index = [itemIndexes indexGreaterThanIndex:index]){ //...get the path you want to add to the pasteboard id myDatasourceItem = [_myDatasourceArray objectAtIndex:index]; NSString *path = [myDatasourceItem myLargeImageFilePath]; //add it to your array [filesArray addObject:path]; } //declare the pasteboard will contain paths [pasteboard declareTypes:[NSArray arrayWithObjects:NSFilenamesPboardType,nil] owner:self]; //set the paths [pasteboard setPropertyList:filesArray forType:NSFilenamesPboardType]; //return the number of items added to the pasteboard return [filesArray count]; } -- Thomas > On Oct 23, 2009, at 6:49 PM, Thomas Goossens wrote: > >> Hi Jordan, >> >> imageBrowser:writeItemsAtIndexes:toPasteboard: is indeed the way to go. >> >> Implement this method in your datasource and just fill the pasteboard with >> the info you want (Images, paths, urls, data...) for the indexes passed in >> arguments. >> Also if you feed the imageBrowser with paths or urls >> (IKImageBrowserPathRepresentationType, >> IKImageBrowserNSURLRepresentationType...) , you don't have to do anything, >> the pasteboard is filled automatically (i.e you don't need to implement >> imageBrowser:writeItemsAtIndexes:toPasteboard:). >> >> -- Thomas >> >> >> On Oct 22, 2009, at 2:30 PM, TFS - Tobias Jordan wrote: >> >>> Hi all, >>> >>> I've been wondering on how to implement dragging out of the view in the >>> IKImageBrowserView.
