Function Reference

GUICtrlRegisterListViewSort

Register a user defined function for an internal listview sorting callback function 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
