XmClipboardCopy(3X)XmClipboardCopy(3X)NAMEXmClipboardCopy - A clipboard function that copies a data item to tem‐
porary storage for later copying to clipboard
SYNOPSIS
#include <Xm/Xm.h> #include <Xm/CutPaste.h>
int XmClipboardCopy (display, window, item_id, format_name, buffer,
length, private_id, data_id)
Display * display;
Window window;
long item_id;
char * format_name;
XtPointer buffer;
unsigned long length;
long private_id;
long * data_id;
DESCRIPTIONXmClipboardCopy copies a data item to temporary storage. The data item
is moved from temporary storage to the clipboard data structure when a
call to XmClipboardEndCopy is made. Additional calls to XmClipboardCopy
before a call to XmClipboardEndCopy add additional data item formats to
the same data item or append data to an existing format. Formats are
described in the Inter-Client Communication Conventions Manual (ICCCM)
as targets.
Note
Do not call XmClipboardCopy before a call to XmClipboardStartCopy has
been made. The latter function allocates temporary storage required by
XmClipboardCopy.
If the buffer argument is NULL, the data is considered to be passed by
name. When data that has been passed by name is later requested by
another application, the application that owns the data receives a
callback with a request for the data. The application that owns the
data must then transfer the data to the clipboard with the XmClipboard‐
CopyByName function. When a data item that was passed by name is
deleted from the clipboard, the application that owns the data receives
a callback stating that the data is no longer needed.
For information on the callback function, see the callback argument
description for XmClipboardStartCopy(3X). Specifies a pointer to the
Display structure that was returned in a previous call to XOpenDisplay
or XtDisplay. Specifies a widget's window ID that relates the applica‐
tion window to the clipboard. The widget's window ID can be obtained
by using XtWindow. The same application instance should pass the same
window ID to each of the clipboard functions that it calls. Specifies
the number assigned to this data item. This number was returned by a
previous call to XmClipboardStartCopy. Specifies the name of the for‐
mat in which the data item is stored on the clipboard. Format is known
as target in the ICCCM. Specifies the buffer from which the clipboard
copies the data. Specifies the length of the data being copied to the
clipboard. Specifies the private data that the application wants to
store with the data item. Specifies an identifying number assigned to
the data item that uniquely identifies the data item and the format.
This argument is required only for data that is passed by name.
RETURN VALUE
The function is successful. The function failed because the clipboard
was locked by another application. The application can continue to
call the function again with the same parameters until the lock goes
away. This gives the application the opportunity to ask if the user
wants to keep trying or to give up on the operation. The function
failed because XmClipboardStartCopy was not called or because the data
item contains too many formats.
