My documents have 2 main view modes, thumbnails and details, which use subclasses of IKImageBrowserView and NSTableView respectively. For printing, I need to create a new print-only thumbnail view because IKImageBrowserView wasn't written in a way that can print, plus I need to rejigger its frame and other things for printing. The NSTableView used in the doc window can be used as-is for printing (as long as I don't allow printing in a background thread, otherwise it screws with its autolayout in the background, which floods the console with exceptions).
I'd like to add pair of radio buttons to my Print panel's accessory view so the user can choose between the 2 modes. To handle this, I create an NSView subclass that simply holds the thumbnail and table views needed to print. Depending on the state of the radios, its drawRect: method will either draw the appropriate view. The are *not* added as subviews, because that would remove them (the table at least) from doc window hierarchy. This appears to work fine for the thumbnail view, but the table view is not drawing anything into the Print preview or into the context when I actually print to pdf. I'm ensuring that when the user changes the view type, I resize the wrapper view to match the frame of the thumbnail or table view. Obviously, the Print panel knows how to cause an NSTableView that's part of a window's view hierarchy to render into the preview and to the print context. How can I get the table to draw in my scheme of things? It doesn't look like the print preview is doing anything sneaky like temporarily moving the view to the print panel or anything like that. Although I do see that it's calling viewWillDraw twice when I move the preview to pages that contain the rows that are visible in the window, first for the print preview then again for the doc window. If I got outside that range, it only gets called once for the print preview. -- Steve Mills Drummer, Mac geek _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
