In previous blog entries we saw how easy it is to implement the Design Pattern Singleton and how we can find the Observer Design Pattern already implemented on several Xojo features by default, greatly simplifying our code and interaction between the objects. Now, as promised, it is time to put it all in practice, creating our own Notification Center: a class that will allow us to share the same unique instance for the entire App (Singleton), and that can use any object in order to register itself for receiving notifications by the observed Control, for one or more message (the notifications themselves).

It is likely that later this week, Microsoft will be announcing Visual Studio for Mac. Is this really true? Why would they do this? What does it mean for Xojo users?

He and his wife, Joy Sha, make up Ohanaware and they have been building award winning apps since 2008, notably Funtastic Photos, HDRtist and Shine.

I’d like to introduce you to Ohanaware’s latest Made With Xojo application we’ve created for us Xojo developers. It’s called “Iconographer” and it is designed to simplify the process of creating stunning and platform-consistent icons for Mac, Windows & iOS.

Guest Post by Christian Schmitz of Monkeybread Software, a Xojo developer from Germany. 18 years ago various consulting projects brought Christian to plugin development for Xojo. Digging through various libraries, OS features and compiler techniques, he built a huge plugin toolbox for use in his own projects and to license to others. Christian has (co)hosted ten conferences over the years and you can join the next one in Berlin.
Do you like to meet other Xojo users and go to conferences? Well, you are in luck! In 2017 there is a conference being organized by Monkeybread Software. Xojo developers from all over the world will meet the first week in May 2017 in metropolitan Berlin, Germany. In the center of western Berlin at the Ellington hotel, next to the nearby Kurfürstendamm, the Zoo and KaDeWe. We selected this central location in Europe for easy traveling for developers from east and west.
