[PATCH v4 0/9] MR5665: For a CS_PARENTDC child use parent for visible region calculations.
These patches fix painting in an application that draws outside of a CS_PARENTDC child client area in its WM_PAINT handler. Comments and suggestions are welcome. -- v4: win32u: Use parent rectangle for visible region calculations of a CS_PARENTDC child. win32u: Don't clip update region to the window client rectangle. win32u: GetUpdateRect() should clip update rectangle to the window client area. win32u: GetUpdateRgn() should clip update region to the window client area. win32u: Clip PAINTSTRUCT.rcPaint to the window client area. server: For a CS_PARENTDC child use parent for visible region calculations. server: If the being validated region covers whole window then validate everything. user32/tests: Add a message test for listbox redrawing after LB_SETCOUNT. user32/tests: Test BeginPaint() clipbox of cropped window with CS_PARENTDC. https://gitlab.winehq.org/wine/wine/-/merge_requests/5665

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.

I think that your test answers this question, because "static" and "parentdc_class" both have CS_PARENTDC style. Not really, since `CS_PARENTDC` is ineffective for an overlapped window. Sorry for confusion. Ok, just tested this, turns out `CS_PARENTDC` is indeed not transitive. Resolving as not an issue.

Rémi Bernon (@rbernon) commented about dlls/win32u/dce.c:
top_win = wine_server_ptr_handle( reply->top_win ); win_rect = wine_server_get_rect( reply->win_rect ); top_rect = wine_server_get_rect( reply->top_rect ); + if (flags & DCX_PARENTCLIP) + { + win_rect.right = top_rect.right; + win_rect.bottom = top_rect.bottom; + }
This doesn't look right, why only the right / bottom coordinates? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5665#note_73395

Sorry, that would take real review work and I'm not ready to do it right now.
and closing 5836?
ACK. Done. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5665#note_73433
