slider parameters & minimal value
« Thread started on: Mar 8th, 2012, 2:43pm » |

1)There is possibility to put max value (*right end) of slider. How to initialize ruler's left end (0 is always there) I need -40
2)By the style 800 I get nice little numbers above ruler. Where to read those numbers for application?
(*) PROC_showtrackbar(tb%, max%)

Send a TBM_SETRANGEMIN message:

Code:SYS "SendMessage", !tb%, TBM_SETRANGEMIN, 1, -40

Sorry, I don't understand the question. Style &800 is TBS_NOTIFYBEFOREMOVE (Vista or later only).

This seems to work now
Thankyous from Dynamic35.
Ps.
Style 800 was an 'accidental' finding and I like it since it seems to work in my XP

Right, so that's 800 decimal, therefore &320 hexadecimal, which is:
Code:TBS_REVERSED + TBS_TOOLTIPS + TBS_ENABLESELRANGE
I suspect the 'little numbers' you referred to are simply the tooltips created by the TBS_TOOLTIPS style.
