Looks like it might be possible to use Datablocks on any version of wxWidgets. Accoding to tech support, "Where DB uses versions, you can simply type in the version to match the wxWidgets version. Not all wxWidgets 3 controls are supported, but often you can use foreign controls (basically wxWindow) and change the class name to match the required class, and DB will generate the code to create the control."
I'll have to check out the trial, thanks!
