background color

[Guest]

I have a StatusWindow on an app with several parts (panels). I want to use the last panel to store the status of the Scroll Lock key. What i want to accomplish is the ability to change the background and foreground colors of that single panel every time the scroll lock key is pressed. I have created a progress bar with a StatusWindow and painted that successfully. I want the text to remain if possible. Is this doable? I think i have been up too long today.

Thanks for any help,
Ron

Can send SB_SETTEXT with SBT_OWNERDRAW to make a part ownerdrawn and then
trap WM_DRAWITEM in parent, where FillRect and TextOut can paint background
and text. MS touches it briefly in "Owner-Drawn Status Windows", in win32.hlp.

Never had need to do it myself, so no sample on that, but there are some for
handling WM_DRAWITEM in other ownerdrawn controls in source code forum.
Should not be big difference, I think.

Did a quick test in PBnote sample and following works. Needs more work,
but can at least show way to do it.

    CASE %WM_MENUSELECT
      LoadString hInst, wParam, zText, SIZEOF(zText)
      SendMessage hStatus, %SB_SETTEXT, 0 OR %SBT_OWNERDRAW, VARPTR(zText) '0 OR - 0 is part, can be 1, 2..
      FUNCTION = 0 : EXIT FUNCTION
 
     CASE %WM_DRAWITEM
        IF wParam = 200 THEN
           LOCAL lpdis AS DRAWITEMSTRUCT PTR, zp AS ASCIIZ PTR
           lpdis = lParam
 
           FillRect @lpdis.hDC, @lpdis.rcItem, GetSysColorBrush(%COLOR_INFOBK)
           SetBkColor @lpdis.hDC, GetSysColor(%COLOR_INFOBK)
           SetTextColor @lpdis.hDC, GetSysColor(%COLOR_WINDOWTEXT)
           zp = @lpdis.itemData
           DrawText @lpdis.hDC, @zp, LEN(@zp), @lpdis.rcItem, %DT_LEFT OR %DT_SINGLELINE OR %DT_VCENTER
           FUNCTION = 1 : EXIT FUNCTION
        END IF

Forgot part in %SB_SETTEXT message - now added..

Borje, thank you very much!

I will let you know how it goes.

Made small DDT sample. Not fully pleased with result, but at least it
shows a way to do it. Maybe someone knows how to reduce/remove flicker?

I didn't notice the flicker, Borje, but I was only pressing the scroll lock key and not moving the mouse.

It looks pretty good although the sb part could be filled in a little better with SB_GETRECT and FillRect(). I had trouble displaying the text while painting.

thanks,
Ron
