With the release of Xojo 2020r1 comes the new 2.0 version of our web framework. While the way in which you build web applications hasn’t fundamentally changed, this new version is a from-the-ground-up rewrite and utilizes API 2.0 for greatly improved consistency. This means that the conversion process is going to be time-consuming, but will be well worth the effort as web applications built upon Web Framework 2.0 will be more robust, handle more users, be more responsive and have a far more modern look and feel.

All of us are used to dealing with that web form where we select a country from a long, long list of more than 200 hundred countries. It would certainly be more useful, less stressful and a better usability practice to preselect the country name from the IP of the client visitor. Continue reading to learn how you can put a bit of intelligence into your web forms using a WebPopupMenu subclass.
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!
Comments closedThis tutorial will show you how easy it is to create animations on components of Xojo web apps, thanks to the use of the Style Editor and the WebAnimator class. Learn how to do a fade effect between two images that you can expand and adapt to your web apps.
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.

In a previous entry we started to dig into web services with Xojo. The first post focused on the backend (server side), creating the Xojo app acting as middleware between the clients and the database that holds your data. We are using SQLite as the backend engine but it would not be difficult to change to other supported database engines like PostgreSQL, MySQL (MariaDB), Oracle or SQL Server, and even ODBC; all of these are supported by Xojo!
Comments closedThe WebCanvas control is used for drawing graphics in web apps. It takes advantage of the HTML5 Canvas making it fast and powerful. Sometimes is can be useful to be able to save the graphics drawn in the WebCanvas to an image file, but unfortunately there is no built-in Xojo method to do this.
However, by using a little JavaScript you can easily add this capability to Xojo.

Using Xojo Web to create complete web apps and solutions means not having to learn a bunch of interpreted languages and dozens of ever-changing frameworks. I’m looking at you: HTML, CSS (is that even a language?), JavaScript, PHP, et al. Of course, Xojo Web not only makes it possible to create your own web apps, but it also acts as the perfect middleware that your desktop and iOS apps can communicate with. Learn about APIs and web services with Xojo in the tutorial blog post.

We’re wrapping up week 9 of #JustCode with a web app that demonstrates a web service, JSON and SQLite. The web app functions as both an app with a UI and a web service. It lets you enter your own quotes which are saved in a SQLite database. The web service randomly fetches a quote and returns it as JSON.

For week five of the Just Code Challenge, I made a web app. My wife is a middle school math teacher and sometimes she needs to give the kids quizzes to help them with their math skills.
Comments closedIf you are just starting the development of your first web app you may be wondering if you need to get a Xojo Cloud server right away. In most cases, the answer is no. You can develop your application on your own computer and sign up for a Xojo Cloud server when you are getting close to deployment and are ready to test in as close to a real world situation as possible.
There are differences of course between how a web app will execute on your computer with a single user (you) versus on a server that is anywhere from hundreds to thousands of miles away with many users connected all at the same time. For the most part, you don’t have to think very much about this but there are areas where you should.
Keep the following 3 things in mind when developing without a cloud server.
