Gridlines display through Text in List View

[BPak]

Hi
I have made this small test application in Easy Code using GO.

When clicking on Stock Menu and then Clicking the bottom ListView Scroll Button the List View Scrolls but has the Gridlines going through the Text.

I have a Mainfest File in the folder.  If I remove the Manifest File then the Gridlines display correctly.

Project Code and Image of ListView showing Gridlines attached!

Any idea on what I may need to do to correct this, please?

Hi BPak,

Yes, you're right. As the Manifest file just enables the Windows Common controls 6.0,  it seems to be a refresh problem of the new Common controls, so I'm afraid I can do nothing about that. Anyway, I have processed the WM_PAINT of the ListView object (in the ListView procedure) like this:

dlgStocklvStock Frame hWnd, uMsg, wParam, lParam
   Cmp D[uMsg], WM_PAINT
   Jne >
   Invoke InvalidateRect, [hWnd], NULL, FALSE
:  Return (FALSE)
EndF

It is not the best solution as it causes some flickering, but it solves the problem. You can play with updating just the bottom part of the ListView client area.

Thanks Ramon.

It works fine. Would need to invalide the whole ListView as the top Button also interferes with the Gridlines display.

Might try some other idea like alternate rows in tinted back color.

Hi BPak,

I have found the way to avoid flickering in the ListView object when Common controls 6.0 are enabled. Delete all code in the ListView procedure and just write this:

dlgStocklvStock Frame hWnd, uMsg, wParam, lParam
   Cmp D[uMsg], WM_VSCROLL
   Jne >
   LoWord ([wParam])
   Cmp Ax, SB_THUMBPOSITION
   Jge >
   Invoke GetParent, [hWnd]
   Push Eax
   Invoke SendMessage, Eax, WM_SETREDRAW, FALSE, 0
   Invoke CallDefaultProc, [hWnd], [uMsg], [wParam], [lParam]
   Pop Eax
   Invoke SendMessage, Eax, WM_SETREDRAW, TRUE, 0
   Invoke InvalidateRect, [hWnd], NULL, FALSE
   Invoke SendMessage, [hWnd], WM_PAINT, 0, 0
   Return (TRUE)
:  Return (FALSE)
EndF


No flicker at all!
