I can never remember all those part codes and tags that are used in  
def Get/SetButtondata() and I regularly have to QuiXample my stash of  
examples. As well as a shed load of other projects, I'm compiling a  
set of easy-to-remember wrappers for some of this stuff. The one  
below was suggested by a VIP in the FB community.

Anyway, I have a general question regarding passing parameters to and  
from functions... In the example, I want(ed) to eliminate the need to  
dim and copy the boolean. I've tried variations of the following:

..., @set as ^Boolean )
... sizeof( Boolean ), #set )

but I either get a compile error or a crash.

Any suggestions?


    Wrapper for def SetButtonData(...PushButtonDefaultTag...)
local mode
local fn PushButtonSetDefault( btnID as long, set as Boolean )
dim as Boolean  @ bool

bool = set
end fn = fn SetControlData( button&( btnID ), _kControlEntireControl,  
_kControlPushButtonDefaultTag, sizeof( Boolean ), bool )

err = fn PushButtonSetDefault( _cBtn, _true )
