Hello,
I have some problems to understand VSCROLL and HSCROLL of DCSTATIC. If I scroll down in my sample, the static scrolls over the button on the top of the dialog. The scrollarea should only be in the area of oStatic2.
I also would like to make the scroll buttons larger. I think I can go throug the getlist and change the size of the object, but is there an easier way to do this ?
regards
Rudolf

Code: Select all

#INCLUDE "dcdialog.CH"

function Main()
******************************************************************
local getlist := {},x,oStatic1,oStatic2
@ 0,0 DCSTATIC TYPE XBPSTATIC_TYPE_RECESSEDBOX SIZE 500,700  OBJECT oStatic1 PIXEL  RESIZE DCGUI_RESIZE_AUTORESIZE_SCALEFONT
@ 1,1 DCPUSHBUTTONXP size 500,40 caption "buttons" PIXEL PARENT oStatic1
@ 42,0 DCSTATIC TYPE XBPSTATIC_TYPE_TEXT SIZE 500,700-42 OBJECT oStatic2 PARENT oStatic1 PIXEL RESIZE DCGUI_RESIZE_AUTORESIZE_SCALEFONT;
                    VSCROLL oStatic1 RANGE 0,500 INCREMENT 10 ;
                    HSCROLL oStatic1 RANGE 0,500 INCREMENT 10

for x := 1 to 100 step 20
     @ x,20 dcsay "Test" saysize 0 parent oStatic2 PIXEL

next x
DCREAD GUI TITLE "Test" FIT EVAL {|o|SetAppWindow(o)}
return .t.

PROC appsys
return

If you want more control, I suggest using DCSTATIC and DCSCROLLBAR commands.

Hello Roger,
thank you, got it working so far. But here I have also the problem that oStatic2 scrolls over the button on the top of the dialog.
How can I make the scroller button higher ?

hi,

your PushButton is on same Parent oStatic1 which Size > ::drawingArea ( which give you vertical Scrollbar )

you have to put your Pushbutton on oDlg and than "resize" o:drawingArea

Code: Select all

   aTmp := oDlg:DrawingArea:Currentsize()
   // on bottom
   oStatbar := Statbar() :new( oDlg ) // oDlg !!!
   oStatbar:Caption := "myStatbar"
   oStatbar:create(,, { 0, 0 }, { aTmp[ 1 ], nHigh }, aPres )
   // new ::drawingArea Pos/Size
   oDlg:DrawingArea:SetPosAndSize( { 0, nHigh }, { aTmp[ 1 ], aTmp[ 2 ] - nHigh } )

Hello Jimmy,
thank you, this is a workaround I think. But how put I the buttons and other things thon on this static area. In Rogers scroll sample there are always 3 statics involved, I wanted to avoid this and do this with 2 statics and the SCROLLBAR option of DCSTATIC. The code to put a simple scrollable area on a static is rather complicated. So if I need this for more different dialogs, it becomes complicated.
