NAME¶

XmClipboardStartRetrieve — A clipboard function that prepares to retrieve data from the clipboard

SYNOPSIS¶

#include <Xm/CutPaste.h>
int XmClipboardStartRetrieve (display, window, timestamp)


        Display * display;


        Window  window;


        Time    timestamp;
(void)

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 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.

RETURN¶

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.
