help for Gdiplus Brush class

Postby Silvio.Falconi » Wed Mar 22, 2023 12:03 pm

is it possible to draw with tGDIPlus a rectangle ( drawrect) with a gradient brush having a style like diagonal lines, around a Get or another control ?


I made a test but not work
Code: Select all  Expand view


Function test()
local oDlg
local oGet,oSay
local cGet:= space(10)
nColor1:= RGB( 245,245,235)
nColor2:=RGB(250,250,245)



DEFINE DIALOG oDlg SIZE 400,100

@ 12,10 SAY  oSay PROMPT "TEST SAY" SIZE 80,12 PIXEL of oDlg
@ 12,90 GET  oGet VAR cGEt SIZE 100,12 PIXEL of oDlg



  oDlg:bPainted := < |hDC|
  TestBrush(hDC,oGet,nColor1,nColor2,oSay:nLeft, oSay:nTop, oSAy:nWidth, oSay:nHeight)
  TestBrush(hDC,oSay,nColor1,nColor2,oGEt:nLeft, oGet:nTop, oGet:nWidth, oGet:nHeight)

 * DRAWBORDER ( hDC, oSay:nLeft, oSay:nTop, oSay:nWidth, oSay:nHeight,0 , 1, nColor1, .t. )

 *DRAWBORDER ( hDC, oGEt:nLeft, oGEt:nTop, oGEt:nWidth, oGet:nHeight,0 , 1, nColor1, .t. )

  RETURN NIL
>

ACTIVATE DIALOG oDlg ;
on init oGet:disable()
          return nil



Function TestBrush(hDC,oControl,nColor1,nColor2, nLeft, nTop, nWidth, nHeight )
local oGraphics := Graphics():New( hDC )

local nRed1 := nRGBRed( nColor1 )
local nGreen1 := nRGBGreen( nColor1 )
local nBlue1 := nRGBBlue( nColor1 )

local nRed2 := nRGBRed( nColor2 )
local nGreen2 := nRGBGreen( nColor2 )
local nBlue2 := nRGBBlue( nColor2 )


local oBrush

local oPen ,nPen:=1


oPen := Pen():New( 255, nRed1, nGreen1, nBlue1, nPen )

oBrush :=  Brush():NewGradientBrush( nTop, nLeft, nWidth, nHeight, 3,;
                         180, nRed1, nGreen1, nBlue1,;
                         180, nRed2, nGreen2, nBlue2)

oGraphics:DrawRect( , oBrush, nLeft, nTop, nWidth, nHeight )

return nil

Dear Silvio, remove call to function TESTWRAPMODE
It was just a test function
