ListView_SetColumnWidth macro (commctrl.h)

Used to change the width of a column in report view or the width of all columns in list-view mode. You can use this macro or send the LVM_SETCOLUMNWIDTH message explicitly.

Syntax

void ListView_SetColumnWidth(
   hwnd,
   iCol,
   cx
);

Parameters

hwnd

Type: HWND

A handle to the list-view control.

iCol

Type: int

The zero-based index of a valid column. For list-view mode, this parameter must be set to zero.

cx

Type: int

The new width of the column, in pixels. For report-view mode, the following special values are supported:

Return value

None

Remarks

Assume that you have a 2-column list-view control with a width of 500 pixels. If the width of column zero is set to 200 pixels, and you make the following call.

ListView_SetColumnWidth(hwnd, 1, LVSCW_AUTOSIZE_USEHEADER)

The second (and last) column will be 300 pixels wide.

Note that ListView_SetColumnWidth converts the cx parameter to a 16-bit value.
