I created my own variation on RSI's CW_FSLIDER and WIDGET_SLIDER which
allowed me to specify intervals (or specific allowable values) for a
slider. It's not an object and it's not well tested but you're welcome
to it if you're interested. (It requires 4 bit map files to provide
Windows-like arrowheads on X displays.)

Hi David,
Oops! I have inherited the creative spelling job for the newsgroup
since Pavel is so scarce these days.
I agree with you about the object thing-a-ma-bob; even if I am just a
scrooling idiot.
Chers,
Been
PS Pavel! Come back!

I think you mean SCROLL. SCROOL is something that comes
out the side of a baby's mouth just as your mother-in-law
bends over to kiss him. :-)
If it comes down to an educational issue (I.e., train the
user to click the proper place on the slider vs. train
yourself to write a compound widget), I know which one
I'm going to vote for as being most likely to succeed.
Cheers,
David

Hi,
I think there is a solution. Interestingly, you can get that behavior
by *not* clicking *on* the slider, but in the space to the left or right
of the slider postion. (I have to say, it also works by clicking on the
slider on my platform - but that is probably not the case on all
platforms) Here's the description of the SCROOL keyword to WIDGET_SLIDER.
Set the SCROLL keyword to an integer value specifying the number of
integer units the scroll bar should move when the user clicks the left
mouse button inside the slider area (Motif) or on the slider arrows
(Windows), but not on the slider itself. The default on both platforms
is 0.1 x (MAXIMUM - MINIMUM), which is 10% of the slider range.

My preference would be for RSI^H^H^HGod to have included a SET_SLIDER_INCREMENT keyword to
WIDGET_CONTROL. Then one wouldn't have to write *any* new software.
Now that's productivity :o)

This is exactly why God made objects. (Well, one
of the *many* reasons, but certainly one of the
most practical.) Write yourself a little compound
widget/object that sets it's own label in units
of 5. You could use a program like FSC_Inputfield
as a rough example:
http://www.dfanning.com/programs/fsc_inputfield.pro
Be careful, though. Once you see how powerful objects
are, and how easy to write, things will never be the
same and your employer will expect even bigger things
from you. :-(
Cheers,
David
