Toolbox

All it would take is for the Display gadget to have a tick box for “multi-line”

That would be a good idea, but you can achieve it fairly simply by manipulating the underlying icon after the gadget has been created.

 DIM valid% 15:$valid%="R2;F17;L":REM new validation string
 SYS"Toolbox_ObjectMiscOp",,Window,68,Display,block%,256:REM icon list
 block%!4=!block%:REM only one icon in Display gadget
 SYS"Toolbox_ObjectMiscOp",,Window,0 TO !block%:REM wimp handle
 SYS"Wimp_GetIconState",,block%
 SYS"Wimp_DeleteIcon",,block%
 block%!32=valid%:REM point to new validation string
 block%!4=!block%
 SYS"Wimp_CreateIcon",,block%+4

That would be a good idea, but you can achieve it fairly simply by manipulating the underlying icon after the gadget has been created.

Yes, but that’s not my point. The Toolbox was intended to make things easier, more direct, and to lift us up a level.

For either solution that you’ve come up with (and kudos to you for doing so!), you just have to know the special sauce, for really a quite mundane requirement.

I’ll continue to agitate for the tick box! And if not a tick box, at least being able to set multi-line via a flag bit.

Hi David,
I understand your efforts
To use the ToolBox I started from the DDE examples and created my own message box.
I assure you, you can do a lot of things with the ToolBox. In fact it is the same kind of tool used by other RAD.
But as you use C and DDE, I will recommend you to use OsLibSupport.
To support my words I built a small demo application, hoping this inspires programmers to use the ToolBox, don’t forget the “bounty” on this.
