XmClipboardStartRetrieve


NAME

XmClipboardStartRetrieve - A clipboard function that starts a copy from the clipboard

SYNOPSIS

#include <Xm/Xm.h>
#include <Xm/CutPaste.h>
int XmClipboardStartRetrieve (display, window, timestamp)
      Display  * display;
      Window   window;
      Time     timestamp;

DESCRIPTION

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 copied.

The return value ClipboardTruncate 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 effect the copy from the clipboard be made between the call to XmClipboardStartRetrieve and the first call to XmClipboardRetrieve. That 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 a widget's window ID that relates the application 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.
timestamp
Specifies the time of the event that triggered the copy. A valid timestamp must be supplied; it is not sufficient to use CurrentTime.

RETURN VALUE

ClipboardSuccess
The function is successful.
ClipboardLocked
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.
