Hi list, Since NSCell is apparently on the way out, I've been trying to build a new control I need using views. It's a cut-down spreadsheet-alike grid, similar to MBTableGrid here: https://github.com/brendand/mbtablegrid
Unfortunately, I am running into the to-be-expected performance trouble with keeping a couple of hundred subviews in my control at the same time. It particularly hurts when scrolling. Stuff I've tried includes: - Removing the off-screen views when possible (still leaves about 150 on screen) - Keeping a queue of reusable views to avoid allocating new ones - Attempting to have one view per grid item type and treat it like an NSCell (i.e., lockFocus into the parent view and draw there) Clearly a smooth-scrolling view-based grid is possible - after all, NSTableView can do it. It's a shame I can't use it for this. Does anyone have any suggestions on how to achieve decent drawing/scrolling performance here? - Ben PS. I have tried using/subclassing NSTableView and have filed a bug for the functionality that I'm after (rdar://17406314 <rdar://17406314> marked as dupe of rdar://2778108 <rdar://2778108>). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
