ListView_SetIconSpacing macro (commctrl.h)
void ListView_SetIconSpacing( hwndLV, cx, cy );
A handle to a list-view control.
The distance, in pixels, to set between icons on the x-axis.
The distance, in pixels, to set between icons on the y-axis.
The cx and cy parameters are relative to the upper-left corner of an icon bitmap. Therefore, to set spacing between icons that do not overlap, the cx or cy values must include the size of the icon, plus the amount of empty space desired between icons. Values that do not include the width of the icon will result in overlaps.
When defining the icon spacing, cx and cy must set to 4 or larger. Smaller values will not yield the desired layout. You can reset cx and cy to the default spacing by setting both values to -1. This approach only allows you to reset both default settings. You cannot reset only cx or cy to the default setting by setting one of them to -1.
