|

|
||||
- (add new items here)
|
||||
- Separated Fl_Spinner.H and Fl_Spinner.cxx (STR #2776).
|
||||
- New method Fl_Spinner::wrap(int) allows to set wrap mode at bounds if
|
||||
value is changed by pressing or holding one of the buttons (STR #3365).
|
||||
- Renamed test/help.cxx demo program to test/help_dialog.cxx to avoid
|
||||
name conflict with CMake auto-generated target 'help'.
|
||||
- Many documentation fixes, clarifications, and enhancements.
