|
// VB SYNOPSIS
|
||
|
|
//
|
||
|
|
// Declare Function ALEntryListToggleMarks Lib "AL20LW"
|
||
|
|
// (ByVal this_object&) As Integer
|

|
|
//
|
||
|
|
// DELPHI SYNOPSIS
|
||
|
|
//
|
||
|
|
// function ALEntryListToggleMarks( this_object : hALEntryList ) : Integer;
|
||
|
|
//
|
||
|
|
// ARGUMENTS
|
||
|
|
//
|
||
|
|
// this_object : A reference or pointer to the ALEntryList object that
|
||
|
|
// is going to be modified. Note that the C++
|
||
|
|
// version of this function doesn't have an explicit argument
|
||
|
|
// here, since it has access to 'this' implicitly.
|
||
|
|
//
|
||
|
|
// DESCRIPTION
|
||
|
|
//
|
||
|
|
// This simple member function just goes through the entire list,
|
||
|
|
// toggling the mark state of every entry. In other words, if the mark
|
||
|
|
// was previously set, it will now be cleared, and vice versa.
|
||
|
|
//
|
||
|
|
// RETURNS
|
||
|
|
//
|
||
|
|
// A count of the number of entries whose mark was changed.
|
||
|
|
// (Just the total number of entries.)
