Scrolling graphics?

Recommended Posts

jimg

I'd like to create a GUI that includes several scrolling (horizontal) line charts (sort of like Performance Monitor or Task Manager's performance windows.

I don't see any way to do this without redrawing everything. Is there a better way?

I think it's fairly simple if you have an image. as shown below. Otherwise have a look at the radar example by monoceres and weaponex.here

#include <windowsconstants.au3>

Global Const $WS_EX_COMPOSITED = 0x2000000

$gui = GUICreate("Scrolling")
GUISetState()
$child1 = GUICreate("screen", 198, 50, 20, 80, $WS_POPUP, BitOR($WS_EX_MDICHILD, $WS_EX_COMPOSITED), $gui)

$n = GUICtrlCreatePic(@SystemDir & "\oobe\images\mslogo.jpg", 0, 0, 200, 50)
$n2 = GUICtrlCreatePic(@SystemDir & "\oobe\images\mslogo.jpg", 199, 0, 200, 50)
GUISetState()
GUIRegisterMsg($WM_MOVE, "redraw")
AdlibEnable("slide", 40)
While GUIGetMsg() <> -3
    
    Sleep(90)
    
WEnd


Func slide()
    Local $p1 = ControlGetPos($child1, "", $n)
    Local $p2 = ControlGetPos($child1, "", $n2)
    Local $newx
    If IsArray($p1) Then
        $newx = $p1[0] - 1
        If $newx <= -200 Then $newx = 199
        ControlMove($child1, "", $n, $newx, $p1[1])
    EndIf
    If IsArray($p2) Then
        $newx = $p2[0] - 1
        If $newx <= -200 Then $newx = 199
        ControlMove($child1, "", $n2, $newx, $p2[1])
    EndIf

EndFunc  ;==>slide

Func redraw()

    DllCall("user32.dll", "int", "InvalidateRect", "hwnd", $gui, "int", 0, "int", 1);force a redraw
    DllCall("user32.dll", "int", "InvalidateRect", "hwnd", $child1, "int", 0, "int", 1);force a redraw
    
EndFunc  ;==>redraw

I need to add live data at the right edge as it scrolls, so it seems a little different, but I'll play with your approach.

You need to do something like this maybe

;run as beta
Global $lastY = 0,$DrawX = 0, $stepx = 4

#include <GDIPlus.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>


Global Const $width = 600
Global Const $height = 200

Opt("GUIOnEventMode", 1)
$hwnd = GUICreate("graph", $width, $height,-1,-1)

GUISetOnEvent(-3, "close")
GUISetState()
GUIRegisterMsg($WM_PAINT, "_Paint")
GUIRegisterMsg($WM_MOVE, "_Move")

_GDIPlus_Startup()

$graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
$bitmap = _GDIPlus_BitmapCreateFromGraphics($width, $height, $graphics)
$background = _GDIPlus_BitmapCreateFromGraphics($width, $height, $graphics)
$backgroundgraphics = _GDIPlus_ImageGetGraphicsContext($background)
$backbuffer = _GDIPlus_ImageGetGraphicsContext($bitmap)
$brush = _GDIPlus_BrushCreateSolid(0xFF005200)
$pen = _GDIPlus_PenCreate(0xFF888800, 3)

_GDIPlus_GraphicsClear($backgroundgraphics, 0xFF000000)

    $drawX += $stepx

    Local $newY = Random(Int($height/4),Int(3*$height/4),1)
    _GDIPlus_GraphicsFillRect($backbuffer, $drawx-$stepx, 0,$stepx+1, $height,$brush)
    _GDIPlus_GraphicsDrawLine($backbuffer, $drawx - $stepx, $lastY , $drawx , $newY, $pen)
    $lastY = $newY

has anyone improved upon this code? when i rattle with the window the graphs speed increases. window size reshape would be nice. its pretty CPU intensive i find or is this standard? i get crash while launching if my CPU is to high. very nice though. decreasing line thickness makes the lines disapear at points which is a shame.
