Horizontal scrolling list ctrl?

Config: Win95 VisC++/MFC 4.1

For my App's gui I would like a single horizontal row of 32x32 icons that
scrolls horizontally.

like:

----------------------------------------
|    -----    -----    -----    -----  |
|    |   |    |   |    |   |    |   |  |
|    |   |    |   |    |   |    |   |  |
|    -----    -----    -----    -----  |
----------------------------------------
| <          "scroll bar"            > |
----------------------------------------

      
I'm using a CListCtrl to achieve this. Using the following create flags I get 
_most_ of the behavior I want:

LVS_ALIGNTOP | LVS_AUTOARRANGE | LVS_ICON

Align top makes them all go in a horizontal row at the top of the view,
auto-arrange keeps them neat, and Icon puts the control in icon mode.

BUT there is _no_ horizontal scroll bar and the default behavior when the
control is sized smaller than it's contents is to show a _vertical_
scrollbar (ugh)

I can't seem to find the appropriate settings to tell it to use a horizontal
one instead. 

Has anyone done this? Is it possible or do I have to do something nasty like
set it no-scroll and embed it in a scrollview I can control directly?

Thanks!

Using LVS_ALIGNLEFT in stead of LVS_ALIGNTOP should do the trick.
Make sure your ListCtrl is just high enough to hold one row of icons.


explanation: 

When adding items with AlignTop, new icons are added along the top untill
the row is full, and then proceeds with a new row ( -> growing 
vertically -> vertical scrollbar)

When adding items with AlignLeft, new icons are added along the left side
untill the column is full, and then proceed with a new column ( -> growing
horizontally -> horizontal scrollbar)

By making your control just one icon high, you get the row you want.

Check out Example 06B from _Inside Visual C++ Version 4_, by David 
Kruglinski; his scrolling CList in the dialog resource is *exactly* what 
you're after.  The .RC code looks like this:

CONTROL         "List1",IDC_LISTVIEW1,"SysListView32",LVS_LIST | 
                LVS_ALIGNLEFT | WS_BORDER | WS_TABSTOP,220,12,120,24,
                WS_EX_LEFTSCROLLBAR

>From within MS Developer Studio you can edit the List control and make the 
following changes:

List Control Properties
  General == Visible and Tabstop checked
   Styles == View: List, Align: Left, Sort: None, Border is checked
 Extended == Left Scroll Bar is checked

Hope this helps!
