Xojo 2019R2 has a lot of new features and enhancements, including the simplification of updating the User Interface in apps from threads running in combination with the main app thread. Doing that in previous releases required the use of a thread in combination with a Timer, for example.
Comments closedAs an Object Oriented Programming language (OOP), Xojo’s data types, especially the non-primitive ones, use or can use a Class hierarchy. This means that one class, either included by default in the Xojo Framework or created from scratch, can act as a base or root class for other classes based upon them.

Continuing with what we previously learned in Animating Xojo, Part 1, this version introduces the use of linear interpolation to calculate the current stage of the animation at each step, plus switching to a Dictionary object for variable storage to setup for future parts in this series.

Comments closedSometime ago a Xojo user asked if it is possible to use Xojo Web to create the kind of animated menus seen in several regular websites. After some investigation (and the invaluable help of Greg O’Lone), the answer is: yes, you can do that! If you are interested in seeing how to achieve this, continue reading!

In order to recreate this fade effect we’ll mainly use a couple of styles (WebStyle class) to set the initial status for each one of our images (instances from the WebImageView class). These will be overlaped in the web page, sharing the same position. Then we’ll add a button to the web page so it will fire the animation every time it is clicked.
