Does PDFView refer to a view containing the enclosing scroll view, or perhaps the scroll view itself? If so, why does -[PDFView drawPage:] exist?
One use is that it can be overridden for all kinds of customization. For instance, you may need to draw a selection rectangle during a drag on a page. You could do that in PDFView's drawPage: method.
- (void)drawPage:(PDFPage *)page { // Draw the source PDFPage [super drawPage:page]; // Draw whatever you want to appear on top of the page. E.g: if (self.masterDocument.onScreenDisplayBoxes > 0) { [self drawOnscreenDisplayBoxesForPage:page]; } if (page == mouseDownPage) { [self drawDraggingFeedbackOnPage:page]; } } -António ---------------------------------------------------- Energy is like a muscle, it grows stronger through being used. ---------------------------------------------------- _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
