[WIN32SS][COMCTL32] Commit Flip_Fix_9.patch
flip_fix_9.patch fixes:
CORE-16984 " 'SPINA Thrulg' / 'SPINA Thyr' / 'Sim Thyr'
have images flipped"
CORE-17194 "StretchDIBits test" isn't work correctly"
"Output of 'Project 3 Test'"
CORE-14701 "DVDStyler 3.0.4 transparent toolbars"
CORE-14701 "DVDStyler 3.0.4 erroneously black around icons of welcome-dlg"
CORE-14671 "'Peazip' shows icons in buttons and menubar vertically
flipped"
"Double Commander shoes icons flipped in buttons, menubar, listview
and the treeview"
CORE-13273 "Welcome to Lazarus" icon shows flipped
CORE-13026 "'CudaText app' icon shows flipped"
Not all of those are duplicates, although they appear to be at first glance.
It affects different controls and some of those tickets do have different 'guilty
revs' than others.
The patch does consist of 3 parts:
1.) win32ss/gdi/ntgdi/dibobj.c
This one is the most clean part of it, that addresses most of the flipping issues
now.
2.) The hack in comctl32.h redefining the version:
We used that in the past to appease some, but not all of the issues listed above.
But it does hide additional issues, e.g. in DvDStyler, therefore we seem to still need
that appeasement even today.
Most likely it would make sense to aim to avoid this part in the future.
part 2.) was committed as first appeasement on its own already into
0.4.14-RC-24-g 198b61e
0.4.13-RC-7-g 67211fa
0.4.12-RC-5-g 8449527
0.4.11-RC-16-g b906163
0.4.10-RC-7-g f1e80fe
0.4.9-RC-34-g 9d758ae
3.) toolbar.c change
That part fixes at least the toolbar case for DvDStyler
without relying on the comctl32.h hack any longer,
but it was still not enough to completely get rid of part 2.) yet.
Many thanks to all contributors: 'I_kill_Bugs', Doug Lyons and also
'Julenuri' for testing.
The patch gave nice testbot results:
KVM: https://reactos.org/testman/compare.php?ids=75704,75714
VBox: https://reactos.org/testman/compare.php?ids=75705,75715
and we also created a summary of manual test-results:
https://jira.reactos.org/browse/CORE-17415?focusedCommentId=126668&page…
If you read this comment via git blame and your goal is to get rid of the hack in
comctl32.h, I would highly recommend
to redo the tests of that testing table, and if that is asked too much, then please
test at least the following cases:
CORE-14701 "DVDStyler 3.0.4 transparent toolbars"
CORE-14701 "DVDStyler 3.0.4 erroneously black around icons of welcome-dlg"
"DVDStyler 3.0.4 erroneously black/transparent within comboboxes of
properties of VMGM menu"
and try to add what might be needed to fix them, and double-check again:
"DoubleCommander optionsDlg the most complex testcase, contains
flip-prone icons in treeview, listview, menubar, buttons, statics". Only some of its
flipped icons were impacted by the comctl32.h change before.
