LB_SETHORIZONTALEXTENT
An application sends an LB_SETHORIZONTALEXTENT message to set the width, in
pixels, by which a list box can be scrolled horizontally (the scrollable width).
If the width of the list box is smaller than this value, the horizontal scroll
bar horizontally scrolls items in the list box. If the width of the list box is
equal to or greater than this value, the horizontal scroll bar is hidden.
LB_SETHORIZONTALEXTENT
wParam = (WPARAM) cxExtent; // horizontal scroll width
lParam = 0; // not used; must be zero
Parameters
cxExtent
Value of wParam. Specifies the number of pixels by which the list box can be scrolled.
Windows 95: The wParam parameter is limited to 16-bit values.
Return Values
This message does not return a value.
Remarks
To respond to the LB_SETHORIZONTALEXTENT message, the list box must have been
defined with the WS_HSCROLL style.
