Hi Martin,
On Tuesday, 29 April 1997 at 22:17:20, Martin Maat confused me
talking about: Owner draw listboxes to Simon Huggins
 SH>> I have managed to create code which deals with
 SH>> putting items wider than the list box onto two lines but
 SH>> not yet managed to get this working for more than that.
 SH>> i.e. to recognise how many then loop through for each one.
 SH>> I tried to set the height variable passed in
 SH>> OnmeasureItem and then inspect it in OnDrawItem but it
 SH>> didn't work :(
 MM> It does work, be carefull not to rely on the
 MM> Items[Index].Object value though, you cannot get to it for
 MM> some from within MeasureItem for some reason. Setting Height

 MM> height is 255 pixels. What is your problem exactly?
Well, I've got long lines of text and I'm trying to find a way of displaying
them in a listbox.
I have worked out a clumsy way of doing it. Find the first word by checking
for spaces, grab it, change the spaces to asterisks * (so that I can use
pos to check for the next space) and see if the temporary line plus this new
word exceeds the boundary.
Repeat until it does then do this a second time.
I had put that in the OnDrawItem bit and in the OnMeasureItem, I checked
to see if items[index] was bigger than the limit. if it was, then it was
two lines long.
At the moment I want to be able to tell if it is 1,2,3,4,5 etc lines long in
onMeasureItem and then refer to that to iterate the correct number of times
in OnDrawItem but I can't seem to access height in OnDrawItem
 SH>> Is there any good reason why OnDrawItem can't be
 SH>> empty?
 MM> Well, you do want something to be drawn, right? The
 MM> beauty of OwnerDraw mode is that nothing will be drawn
 MM> unless you want it to.
Or even if you want it too it will go off the edge ;)
 SH>> Is there a much more elegant solution (there must be
 SH>> somewhere)
 MM> This is as elegant as it gets. Did you set the draw
 MM> mode to OwnerDrawVariable? You need to do this in order to
 MM> be able to set the height of individual items.
Yep, I worked that out but, I thought that someone *MUST* have some code
somewhere which does something similar.
Thanks for the reply,
bfn,
si.
