GUICtrlCreateListView Making a column bigger

[bucky002]

How can I make the column the full size of the box. Well, like this.

Instead of only 1/4 of the way. I hope you understand here is a code I wrote up that replicates it.

$Form1 = GUICreate("AutoIt", 507, 373, 187, 121)
$List1 = GUICtrlCreateListView("Items", 15, 92, 211, 250, 253)

GUISetState()

While 1
    Sleep(500)
WEnd

Thanks.

#include <GuiListView.au3>
GUICtrlSendMsg($List1 , $LVM_SETCOLUMNWIDTH, 0, 300)

0 is zero based index to array of colums

300 is width of column in pixels
