DwtBeginCopyToClipboard(3Dwt) DwtBeginCopyToClipboard(3Dwt) Name DwtBeginCopyToClipboard - Sets up storage and data structures to receive clipboard data. Syntax int DwtBeginCopyToClipboard(display, window, clip_label, widget, callback, item_id) Display *display; Window window; DwtCompString clip_label; Widget widget; VoidProc callback; long *item_id; Arguments display Specifies a pointer to the Display structure that was returned in a previous call to XOpenDisplay. For information on XOpenDis- play and the Display structure, see the Guide to the Xlib Library: C Language Binding. window Specifies the window ID that relates the application window to the clipboard. The same application instance should pass the same window ID to each clipboard function that it calls. clip_label Specifies the label to be associated with the data item. This argument is used to identify the data item, for example, in a clipboard viewer. An example of a label is the name of the application that places the data in the clipboard. widget Specifies the ID of the widget that will receive messages requesting data previously passed by name. This argument must be present in order to pass data by name. Any valid widget ID in your application can be used. All message handling is done by the cut and paste functions. callback Specifies the address of the callback function that is called when the clipboard needs data that was originally passed by name. This is also the callback to receive the DELETE message for items that were originally passed by name. This argument must be present in order to pass data by name. item_id Specifies the number assigned to this data item. The application uses this number in calls to DwtCopyToClipboard, DwtEndCopyTo- Clipboard, and DwtCancelCopyToClipboard. Description The DwtBeginCopyToClipboard function sets up storage and data structures to receive clipboard data. An application calls DwtBeginCopyTo- Clipboard during a cut or copy operation. The data item that these structures receive then becomes the next-paste item in the clipboard. The widget and callback arguments must be present in order to pass data by name. The callback format is as follows: function name(widget, data_id, private_id, reason) Widget *widget; int *data_id; int *private_id; int *reason; widget Specifies the ID of the widget passed to DwtBeginCopyToClipboard. data_id Specifies the identifying number returned by DwtCopyToClipboard, which identifies the pass-by-name data. private_id Specifies the private information passed to DwtCopyToClipboard. reason Specifies the reason, which is either DwtCRClipboardDataDelete or DwtCRClipboardDataRequest. Return Values This function returns one of these status return constants: ClipboardSuccess The function is success- ful. ClipboardLocked The function failed because the clipboard was locked by another appli- cation. The application can continue to call the function with the same parameters until the clipboard is unlocked. Optionally, the applica- tion can ask if the user wants to keep trying or to give up on the opera- tion.
