Speeding Up TextArea Modifications In OS X

Published December 28, 2015 by Joe Ranieri

When doing a lot of manipulation to a TextArea’s contents under Cocoa, performance can suffer due to the underlying NSTextView doing work on layout and glyph selection. This can be sped up by telling the text view that you’re going to begin editing. You can do this by using a few Cocoa Declares.

But it’s not precise: A floating point values primer

Published December 10, 2015 by Norman Palardy

From time to time we see the issue raised where floating point values are not exact like we can write in the code editor or on paper. Usually the confusion or complaint is worded like “I can’t get my double value to be precise like in the string” or “It’s not the same as I get doing it by hand”.

O Retina, Retina, wherefore art thou Retina?

Published December 8, 2015 by Geoff Perlman

During my keynote address last April at XDC, the Xojo Developer Conference, I said that we would be adding Retina support (the OS X feature that provides for ultra-high resolution displays) to the OS X framework in the 4th quarter of this year. We have been working very hard on Retina support both for the OS X framework and for the IDE itself. We didn’t want to stop there though. Windows also supports ultra-high resolution displays. For Windows, this technology is called HiDPI. Xojo is a cross-platform tool so we decided we should support both Retina and HiDPI, and do it in such a way that you don’t have to do much of anything and they just work.

UPDATE: Xojo Retina is here, April 2016
