DispEnd

DispEnd

Display buffered screen updates

Syntax

      DispEnd() --> NIL

Returns

DispEnd() always returns NIL.

Description

DispEnd() is a screen function that informs the Harbour display output system that the application has finished performing a series of display operations.

DispEnd() is used with DispBegin() so the display output system can buffer display updates. This can be important for applications in which complex screen displays are slow and the appearance of performance is desired.

Examples

      .  This example buffers screen output, updates the screen, and
      then displays the buffered screen output:

      DispBegin()            // Start screen buffering
      //
      SetPos(10, 10)
      DispOut("A display update")
      SetPos(11, 10)
      DispOut("Another display update")
      //
      DispEnd()               // Display buffered screen data
