Possible to make square rather than round radio buttons?

Question:
I am developing an application that automates government-defined forms, and have defined the forms using DataWindows. For items such as MALE/FEMALE, YES/NO, etc., I have used radio buttons. But I have been notified that in order to gain approval on these forms, my radio buttons should be squares instead of circles. Is this possible in PB 5.0, and if not, are there any other options? The platform is Windows NT 3.51 as well as Windows 3.1

Answer:
The default look for radio buttons in Windows is round. A square shape is used to represent a checkbox. It may be possible that when your forms were reviewed, the reviewer meant that they should be checkboxes instead of radio buttons. I strongly advise against changing this, because one of the major benefits of a GUI is that things should work the same from application to application.

However, if this is not the case and you must change the look and you have used DataWindow for your forms, you can fake the radio button to look like anything you want, including squares.

You will need to draw small bitmaps that look like the empty and filled radio buttons. Then place a computed column over the top of the displayed radio button. Make the computed column an expression that returns a bitmap, and based on the value of the column return the correct bitmap:

bitmap( col1 = 'Y', 'open.bmp', 'close.bmp' )
Then when the user clicks on the bitmap, the radio button will change its value and the bitmap display will change.
