Here are the questions people asked during our February “What is Xojo” webinar. Did you miss the webinar? It’s less than 30 minutes and you can watch it right here:

Sooner or later your app will need to work with files, maybe to save the data generated with the app itself, to open the files created with other apps or because is the main purpose of the utility you are working on. Xojo gives you the class FolderItem fully loaded with a useful bunch of properties that allow you to examine the attributes of any file; for example, the creation or modification of dates, the file path (in several formats), if the file is an alias, etc. The FolderItem class also gives you the methods to do a lot of file operations without effort.
Comments closedWith all the Retina/HiDPI work done in the past few years, we’ve had to add some new features along with it. One of these newer features is the Graphics ScaleX and ScaleY properties. For the purposes of Retina/HiDPI, the scale factor is used when converting user space coordinates to backing store coordinates. While mostly integral on MacOS (unless originating from some code that’s probably not ours), it can vary on Windows, and perhaps arguably mostly fractional. This is because Windows allows you to set DPI scales at 125%, 150%, etc. So when dealing with fractional scales there are a few things to watch out for:
- Rounding issues
- Anti-alias effect
While the framework takes care of rounding issues, for the most part, the secondary issue of anti-aliasing is up to you.
Comments closedXojo is a modern, powerful programming language with an IDE that simplifies all kind of tasks related your project creation and deployment. One such helpful feature is the UI layout design; you can find it under the Library Panel, it’s a meaningful collection of graphic classes (Controls) ready to use in our apps. Probably one of the first and most used controls in apps design is the TextField, TextField simplifies the way an app can get the input from the user. Let’s see its main properties and how this control behaves when used in Desktop, Web (WebTextField) and iOS (iOSTextField) apps!

Comments closedIn desktop apps, you can use Xojo.Core.Locale to get the user’s locale for formatting dates and numbers. However, in a web app this value returns the locale used by the web server rather than the locale of the current user session.
To display dates formatted in the locale of the user session, you need to get the LanguageCode from WebSession and use that to create a locale that you can then use to display the date.
Comments closedYou already know, you can use Xojo to create practically any kind of application; from apps used by corporations, Universities and even Government agencies around the world, to apps used by photographers, designers and, of course, developers; and even those small utilities that makes our lives a bit easier.
In fact, a lot of these little utilities are what are known as Wrappers. That is, a nice user interface that simplifies and makes more user friendly a feature that is already available in the native operating system; often, in the form of one or more combined commands that need to be typed from the Command Line prompt.

Comments closedIDE Scripts to the rescue! With a simple script (less than 10 lines), whenever you have quoted text to paste into the IDE, just select your script from the File > IDE Scripts menu instead.
