Filling a window fragment

[Natter]

The FloodFill function() fills the DC of the entire window. How can this be done for a specific area of the window?

Dear Yuri,

You may use FillRect():

FillRect( hDC, { nTop, nLeft, nBottom, nRight }, hBrush ) --> nSuccess (0 or 1)

Example of use:

Code: Select all | Expand

#include "FiveWin.ch"  
  

function Main()  
  

   local oWnd  
  

   DEFINE WINDOW oWnd TITLE "FillRect Example"  
  

   ACTIVATE WINDOW oWnd ON PAINT PaintArea( oWnd )  
  

return nil  
  

function PaintArea( oWnd )  
  

   local oBrush  
  

   DEFINE BRUSH oBrush COLOR RGB( 255, 0, 0 )       // red  

   FillRect( oWnd:hDC, { 10, 10, 100, 200 }, oBrush:hBrush )  

   RELEASE BRUSH oBrush  
  

   DEFINE BRUSH oBrush COLOR RGB( 0, 0, 255 )       // blue  

   FillRect( oWnd:hDC, { 110, 10, 200, 200 }, oBrush:hBrush )  

   RELEASE BRUSH oBrush  
  

return nil
