Blog about the Xojo programming language and IDE
A reader asked me to clarify something about my previous post. Their question was:
Comments closedWhen MyMethod is written as:
Sub MyMethod( i() as integer ) i = array(10,20,30) system.debuglog CurrentMethodName + " i(0) = " + str(i(0)) + " i(1) = " + str(i(1)) + " i(2) = " + str(i(2)) End SubWhat happens if instead of trying to assign a new array you just alter the values in the array passed in?
Let’s talk about the difference between a “reference type” and the BYREF modifier on a passed parameter.
Comments closedHere’s your first reminder: On January 14, 2020 Microsoft is ending support for Windows 7. We went through this a while ago when Windows XP reached end-of-life (no one really cared when Windows Vista reached end-of-life). Windows 7 was a very popular release as it was much better than Vista. It also didn’t help that Windows 8 was not liked at all with its many UI changes.
Comments closedDid you know that it’s possible to load and use 3rd Party Frameworks in your Xojo iOS projects? There’s quite a number of good projects out there, many of which are on sites like GitHub and freely available for use in your projects. If you’re familiar with Declares in iOS, loading a 3rd Party framework requires just a couple of extra lines of code and a CopyFilesStep.
Last year at XDC 2018, Jérémie Leroy talked about making sure your screenshots mimicked the Apple method so that the date was always Jun 9th, the time was always 9:41 AM, the battery always shows as full and the WiFi strength always shows full. It got me thinking that it might be handy to be able to make the simulator always show those values when you do a debug run so that you don’t need to think about it when you are ready to start taking screenshots and movies of your app. One way to do that is to build & run project like SimulatorStatusMagic on the simulator before running your project, but it would be more useful if it was automatic.
Comments closedThe only built-in gesture for undo on iOS at the moment is to shake the device. This is not very intuitive to me and I’ve certainly done it by accident many times. The makers of Procreate chose a two-finger tap and have found that their users adapted to it nicely. This gesture is being adopted by more and more iOS developers. Here’s all the code you need to implement the two-finger tap for undo in your Xojo iOS apps.
Comments closedIf you are using SQLite you might be trying to share your database. What are your options when you want to be able to share your database?
Comments closedGitHub just announced that private repositories are now free. GitHub has been a great source for Xojo open-source projects, so being able to also use it for private repositories is a nice bonus.
Comments closedSo you’ve created an app that you plan to sell, now you’re done, right? Nope, not even close! Developing your app is just step one. Marketing and promoting your app is the key to its commercial success, starting with announcing it. We talked to one successful Xojo developer who has several apps in the App Store. He told us that he spends 50% of his time on development and 50% of his time on marketing. Marketing. You think it’s just something for the Pros or people with a big offering, but it’s not.
Making sure everyone knows about your new app or latest update is really important. I have been in PR/Marketing for many years and have seen it all! The biggest mistake I see is developers forgetting to put a link back to their website or sitelet when talking about their app. In announcements and on social media it’s so important to make sure people can find you easily! Here are the 3 most essential steps you should take when announcing your app (or release) to the world.
There are low-code platforms that don’t provide ability to call directly into the operating system. Fortunately, Xojo does. Our vision for Xojo has always been to make the tool easy to learn and highly productive to develop applications, without sacrificing power when you need it.
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.
