Excerpt of article text...

A little history. I first discovered REALbasic in 2003, a little after I switched from Linux to OS X. I wrote a few programs for myself and others, but was generally too busy with my regular consulting to write anything major. For the past fifteen years or so my main development platform has been Filemaker. It is great for database development, but there are always additional things one could wish for (just as there are for Xojo and other development platforms).

In recent years, the cost of licensing Filemaker server and connections has increased greatly. This makes it difficult for small businesses or individuals looking for a database solution to justify the cost. I, like some other Filemaker developers, am looking at Xojo as a way of servicing these clients.

One of the features of Filemaker is the ability to tie checkboxes to a database field. You do this by creating what is called a "Valuelist" which can be a series of terms separated by a carriage return or is actually tied to a field in another table and then tying this Valuelist to the field (see Figure 1). The items that are checked off are then stored in the field separated by carriage returns. This is an ability I greatly wanted to be able to have in Xojo. This project is my take on it.

Creating a ValueList

First we need to create a control array on the window where you want the checkboxes to appear (see Figure 2). There's information on how to do this on the Xojo forum (https://forum.xojo.com/t/making-a-control-array/8546).

Make sure that you turn on the transparent property of the checkbox so that it doesn't show on the main window. I decided to place mine just above the actual window.
