#JustCode Challenge Week 8 – JumpStart App Launcher

A long, long time ago (1989) one of the first apps I ever made was an app launcher for the Atari ST. I called it JumpSTART. I originally wrote it in GFA BASIC and then later re-implemented it in Pascal (OSS Personal Pascal, technically).

When I got my first modem I went online with Genie and Delphi and uploaded JumpSTART as freeware. Even though it was freeware, I got a few checks in the mail from people that liked it.

I was reminded of JumpSTART when I saw my dock getting crowed. I thought replicating JumpSTART in Xojo would be a good project for week 8 of #JustCode. Though let’s just call it JumpStart this time around.

#JustCode Challenge Week 6 – Bubble Popper

For this week’s app, I created a simple iOS app where you tap on “bubbles” to pop them. This was actually suggested to me by Dana Brown some time ago as something that would make a great diversion for her son. I have found it helpful with some of my younger nieces and nephews.

This iOS app demonstrates the use of a Canvas and the detection of taps. When all the bubbles have been popped, more are added. It never ends!

#JustCode Challenge Week 1 – Color Picker

It’s the first week of the Just Code challenge so I’m starting with something pretty simple. This app lets you choose a color using the system color picker and then shows you the color values in hexadecimal (useful for programming, HTML and CSS), RGB (red, green, blue), HSV (hue, saturation,value) and CMY (cyan, magenta, yellow).

Create Your Own ImageWell Based on Canvas

Whether you are using Xojo to create your very first application or if you are coming from other languages, like C# or VisualBasic, customized UI controls are probably one of those things you have in your to-do list. For multiplatform Desktop apps, you will find that the Canvas class offers everything you need. In order to show you how easy it can be, follow this tutorial to recreate the ImageWell UI class control, provided by default in the Xojo framework. Our customized ImageWell will be able to proportionally display any JPEG file dropped by the user on the control, centering it on the available surface.
