Tk::clipboard - Manipulate Tk clipboard
This command provides an interface to the Tk clipboard,
which stores data for later retrieval using the selection mechanism.
In order to copy data into the clipboard, clipboardClear
be called, followed by a sequence of one or more calls to
. To ensure that the clipboard is updated atomically, all
appends should be completed before returning to the event loop.
The following methods are currently supported:
Claims ownership of the clipboard on $widget's display and removes
any previous contents. Returns an empty string.
Appends data to the clipboard on $widget's
display in the form given by type with the representation given
by format and claims ownership of the clipboard on $widget's
Type specifies the form in which the selection is to be returned
(the desired ``target'' for conversion, in ICCCM terminology), and
should be an atom name such as STRING or FILE_NAME; see the
Inter-Client Communication Conventions Manual for complete details.
Type defaults to STRING.
The format argument specifies the representation that should be
used to transmit the selection to the requester (the second column of
Table 2 of the ICCCM), and defaults to STRING. If format is
STRING, the selection is transmitted as 8-bit ASCII characters.
See the Tk::Selection documentation for explanation of what happens
if format is not STRING.
Note that arguments passed to
clipboardAppend are concatenated before conversion, so the
caller must take care to ensure appropriate spacing across string
boundaries. All items appended to the clipboard with the same
type must have the same format.
A -- argument may be specified to mark the end of options: the
next argument will always be used as data.
This feature may be convenient if, for example, data starts
with a -.
- $widget->clipboardGet( ?-type? );
Retrieve data from the clipboard on widget's display.
-type specifies the form in which the data is
to be returned and should be an atom name such as STRING or
FILE_NAME. Type defaults to STRING. This command is equivalent
to "SelectionGet( -selection => 'CLIPBOARD' )".
