Just out of curiosity,
The Win32 Group Box control is actually a Button control with the style BS_GROUPBOX applied. As the control is static, being simply text with a special border, why is it one of the Button styles, when the rest are all for actual buttons or button-like UI elements which receive user input?
Thanks in advance for any insights.
This goes way back to the 1980s. Everybody that worked on it is drinking pina coladas in Hawai today so we’ll have to make-do with a guess. The likely one is that, since it was so very important to minimize the foot-print of Windows back then, that the existing plumbing for the BUTTON control was re-usable to implement a group box as well.
