XmClipboardStartRetrieve — A clipboard function that prepares to
retrieve data from the clipboard
#include <Xm/CutPaste.h>
int XmClipboardStartRetrieve (display, window, timestamp)
Display * display;
Window window;
Time timestamp;
(void)
XmClipboardStartRetrieve tells the clipboard routines that the
application is ready to start copying an item from the clipboard. The
clipboard is locked by this routine and stays locked until
XmClipboardEndRetrieve is called. Between a call to
XmClipboardStartRetrieve and a call to XmClipboardEndRetrieve,
multiple calls to XmClipboardRetrieve with the same format name result
in data being incrementally copied from the clipboard until the data in that
format has all been retrieved.
A return value of XmClipboardTruncate from calls to
XmClipboardRetrieve indicates that more data remains to be copied in
the given format. It is recommended that any calls to the Inquire
functions that the application needs to make to complete the copy from the
clipboard be made between the call to XmClipboardStartRetrieve and
the first call to XmClipboardRetrieve. This way, the application does
not need to call XmClipboardLock and XmClipboardUnlock.
- display
- Specifies a pointer to the Display structure that was returned in a
previous call to XOpenDisplay or XtDisplay.
- window
- Specifies the window ID of a widget that relates the application window to
the clipboard. The widget's window ID can be obtained through
XtWindow. The same application instance should pass the same window
ID to each of the clipboard functions that it calls.
- timestamp
- Specifies the time of the event that triggered the copy. A valid timestamp
must be supplied; it is not sufficient to use CurrentTime.
- XmClipboardSuccess
- The function is successful.
- XmClipboardLocked
- 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.
