GUICtrlRegisterListViewSort ( controlID, "function" ) Parameters controlID The listview controlID for which the user function should proceed. function The name of the user function to call when the sorting callback runs. Return Value Success: 1 Failure: 0 Remarks !!! To make the user function workable you have to define it with maximum 4 function parameters otherwise the function won't be called !!! i.e: Func MySortFunction($nListViewID, $LParam1, $LParam2, $nColumn) EndFunc Or Func MySortFunction($nListViewID, $LParam1, $LParam2) EndFunc When the user function is called then these 4 parameters have the following values: Position Parameter Meaning 1 controlID The controlID of the listview control for which the callback function is used. 2 lParam1 The lParam value of the first item (by default the item controlID). 3 lParam2 The lParam value of the second item (by default the item controlID). 4 column The column that was clicked for sorting (the first column number is 0). The following values have to be Returned to change the behaviour of the sorting callback: Return value Meaning -1 1st item should precede the 2nd. 0 No Change. 1 1st item should follow the 2nd.
