How do I "Shade" a button in wimp Basic

I am having trouble working out how to shade out a button so it can’t be clicked, until a process is ready I have been searching for several evenings and not found the answer. A hint would be appreciated. I am using Basic.

Thanks in Advance

Set bit 22 (icon is shaded).

If blk% is your wimp poll block, window% is a window handle, and icon% is an icon handle, this will do it:

REM Shade (disable) icon
blk%!0  = window%
blk%!4  = icon%
blk%!8  = 1 << 22   : REM EOR word
blk%!12 = 1 << 22   : REM Clear word
SYS "Wimp_SetIconState",, blk%


REM Unshade (enable) icon
blk%!0  = window%
blk%!4  = icon%
blk%!8  = 0         : REM EOR word
blk%!12 = 1 << 22   : REM Clear word
SYS "Wimp_SetIconState",, blk%

Thanks, for that I will see how I get on and report back. I have been using Dr Wimp and that hides some of this stuff.

Note you might want to be careful with the term “wimp Basic”. There was a product from Clares (was it ever 32-bitted? <shrug/>) called “WimpBasic” which provided a BBC BASIC-like language for programming the WIMP.

Personally, I think you’re better off with something using BBC BASIC proper, such as Dr Wimp or <plug> WimpWorks </plug>.

The WIMP StrongHelp manual is invaluable for this kind of stuff, and you can often guess from the SWI names.

Thanks,

I got it working. I am sorry if my terminology was a bit lax, I have not been on the riscos scene for a long time. WimpWorks looks interesting
