$changed


        public
            bool
    $changed
     = false

$clipData

Clipboard data kept here


        public
            array<string|int, mixed>
    $clipData
     = []

Keys: 'normal' 'tab_[x]' where x is >=1 and denotes the pad-number 'mode' : 'copy' means copy-mode, default = moving ('cut') 'el' : Array of elements: DB: keys = '[tablename]|[uid]' eg. 'tt_content:123' DB: values = 1 (basically insignificant) FILE: keys = '_FILE|[md5 of path]' eg. '_FILE|9ebc7e5c74' FILE: values = The full filepath, eg. '/www/htdocs/typo3/32/dummy/fileadmin/sem1_3_examples/alternative_index.php' or 'C:/www/htdocs/typo3/32/dummy/fileadmin/sem1_3_examples/alternative_index.php'

'current' pointer to current tab (among the above...)

The virtual tablename '_FILE' will always indicate files/folders. When checking for elements from eg. 'all tables' (by using an empty string) '_FILE' entries are excluded (so in effect only DB elements are counted)

endClipboard()

Call this after initialization and setCmd in order to save the clipboard to the user session.


    public
                    endClipboard() : void

The function will check if the internal flag ->changed has been set and if so, save the clipboard. Else not.

    public
                    getSelectedRecord() : array<string|int, mixed>

Return values

array<string|int, mixed> —

Element record with extra field _RECORD_TITLE set to the title of the record

hasElements()

Returns true if the clipboard contains elements


    public
                    hasElements() : bool

Verifies if the item $table/$uid is on the current pad.


    public
                    isSelected(string $table, string|int $identifier) : string

If the pad is "normal" and the element exists, the mode value is returned. Thus you'll know if the item was copied or cut.

Parameters

$identifier : string|int: Either the records' uid or a filepath

Return values

string —

If selected the current mode is returned, otherwise an empty string

    public
                    lockToNormal() : void

Trying to switch pad through ->setCmd will not work. This is used by the clickmenu since it only allows operation on single elements at a time (that is the "normal" pad)

pasteUrl()

pasteUrl of the element (database and file) For the meaning of $table and $uid, please read from ->makePasteCmdArray!!! The URL will point to tce_file or tce_db depending in $table
