One of the big changes in Web Framework 2.0 is that web styles are no longer the primary means of styling controls. Instead themes are used to provide a single, consistent look and feel across the entire application. We made this change because dealing with individual styles became more complex and unwieldy as projects grew bigger. Themes simplify this dramatically.

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.

Xojo 2020r1 brings a highly requested feature to the Xojo IDE: the ability to create PDF documents from code! Now you can use the already familiar methods in Xojo’s Graphics class to create Standard PDF 1.4 documents with the PDFDocument class.
Comments closedOn the forum a user asked if there was a way to create a rectangle with only the top left and top right corners being rounded. Xojo’s built-in RoundRectangle control draws with all four corners rounded, so that was not an option.
One solution is to use a GraphicsPath to draw exactly what you want. With a GraphicsPath you can use the AddArc() method to add rounded corners and then draw the lines for the rest of the rectangle.

Comments closedARC4 is a symmetric encryption algorithm fast and easy to implement. Being symmetric does means that it uses the same function with the same key (varying from 40 to 2048 bits) both for cyphering and de-cyphering a block of data.
Is it the most secure or robust encryption algorithm around? Not really. But it provides a good amount of performance and you can take further steps in order to correct some of its flaws. So, continue reading if you are interested in having this one in your developer toolset implemented as a Class with separate methods to encrypt and decrypt a block of information (even if it uses the same function in both cases).
Comments closedMy own projects have #PRAGMA warning “TODO” in the App.Open event. Wherever you want a ToDo note in your code type #PRAGMA warning “Your message”.
Comments closedSure you can create a Subclass of any Picture, Canvas or class and write code to center another Picture in its respective Graphics contexts. But taking the class extension approach means that you can reuse the same code for any of these (or any additional class) offering a Graphic context, so you can pass along the Picture you want to center and re-scale (if needed) in its area.
Comments closedThe Xojo Web Framework offers the WebLink class ready to use which handles showing the text with the proper visuals and the opening of the underlying URL in the browser. But if you need to have that feature on Desktop, it’s not that hard! Continue reading so I can show you one possible implementations to create your own LinkLabel class on Desktop.
