REPASTE_VIRTUAL_DISPLAY - Repaste Virtual Display

Repastes a virtual display on the pasteboard and changes the pasting order. Use vms_smg.move_virtual_display() to move the location and keep the pasting order of the display within the pasteboard.

Format:

    vms_smg.repaste_virtual_display (display_id, pasteboard_id, \
            pasteboard_row, pasteboard_column, [top_display_id])
Returns:

None

Arguments:

display_id
Virtual display to be moved
pasteboard_id
Pasteboard on which the virtual display is to be moved.
pasteboard_row
Specifies the row of the pasteboard that is to contain row 1 of the new location of the specified virtual display.
pasteboard_column
Specifies the column of the pasteboard that is to contain column 1 of the specified virtual display.
top_display_id
Identifier of the virtual display under which the moving display_id will be pasted.
Examples:
>>> import vms_smg
>>> import vms_smgdef

>>> # create a new DECwindows terminal using SMG
>>> status, pasteboard_id, number_of_pasteboard_rows, \
... number_of_pasteboard_columns, type_of_terminal,   \
... device_name = vms_smg.create_pasteboard           \
...   (None, vms_smgdef.SMG_M_WORKSTATION)
>>>

>>> # create virtual display 1
>>> status, vtdpy1 = vms_smg.create_virtual_display \
...         (5, 10, vms_smgdef.SMG_M_BORDER, None, None)
>>>

>>> # write to virtual display 1
>>> status = vms_smg.put_chars (vtdpy1, 'V1', 0, 0)
>>>

>>> # create virtual display 2
>>> status, vtdpy2 = vms_smg.create_virtual_display \
...         (5, 10, vms_smgdef.SMG_M_BORDER, None, None)
>>>

>>> # write to virtual display 2
>>> status = vms_smg.put_chars (vtdpy2, 'V2', 0, 0)
>>>

>>> # paste virtual display 1
>>> status = vms_smg.paste_virtual_display \
...          (vtdpy1, pasteboard_id, 3, 5, None)
>>>

>>> # paste virtual display 2
>>> status = vms_smg.paste_virtual_display \
...          (vtdpy2, pasteboard_id, 5, 7, None)
>>>

Notice that the display 1 is at a new location, now occludes virtual display 2 and the cursor position has changed, too (which does not happen when using vms_smg.move_virtual_display).
