LVM_GETSTRINGWIDTH message

  • Artikkel

Determines the width of a specified string using the specified list-view control's current font. You can send this message explicitly or by using the ListView_GetStringWidth macro.

Parameters

wParam

Must be zero.

lParam

Pointer to a null-terminated string.

Return value

Returns the string width if successful, or zero otherwise.

Remarks

The LVM_GETSTRINGWIDTH message returns the exact width, in pixels, of the specified string. If you use the returned string width as the column width in the LVM_SETCOLUMNWIDTH message, the string will be truncated. To retrieve the column width that can contain the string without truncating it, you must add padding to the returned string width.
