[PATCH v12 0/5] MR10191: Draft: comctl32: Implement Tile view style
by Huw Campbell (＠HuwCampbell) Feb. 26, 2026

Feb. 26, 2026

The Tile View in common controls offers a compact and pretty nice way to show some additional context within the list view, without resorting to the full reports mode. It's used a lot in explorer like programs where things like the disk size and file type are shown. But, it's been sitting unimplemented in wine for a long time. I've just spent a few days implementing this by: - Building a small test program in windows to get a feel for how it works - Hacking just enough to get something displaying - Writing a test suite to try and understand the ownership model, getting, and setting, and the various messages passed by windows. - Fixing up the implementation. - Adjusting my program to use I_COLUMNCALLBACK in windows and testing that. - Fixing my implementation to match the behaviour observed. Full disclosure, I wrote this implementation within the ReactOS build system then copied back the diff as I had that compiling already on my Windows box, and my Mac is an M1 so doesn't play very nicely with Wine. So while I built this code on my Mac in Wine, I can't actually run it there. I'll install a Linux virtual machine at some point and do some testing there too. All bugs and misunderstandings are my own; I used clean room techniques (read MSDN, write a test program, write tests, compare results, iterate). Interesting things: - I initially wrote layout code for tiling mode as well, but a few rounds of playing with my test program and various layouts and settings (things like `LVS_ALIGNTOP`, `LVS_AUTOARRANGE` and `LVS_ALIGNLEFT`) for both tile mode and icon mode convinced me that they same layout logic (or close enough to). - I noticed some differences in Wine's Icon mode layout as compared to Windows 10. - I didn't fix these, one thing at a time. - I noticed and fixed a bug in SetView, where `UpdateItemSize` was called _after_ `Arrange`; that doesn't work. - The Text colours are really odd, if set to black the sub items show up gray, but any other colour and they're the same as the main. - Layout is tricky, in windows it looks like the first item (file name for example) can flow to 2 lines, and subitems are restricted to 1 - But this is really subtle, using GetItemMetrics kind of assumes there's no 'interference' from other items. - If we're on subitem 2, I don't want to have to fetch 0 and 1 to render their sizes before calculating my own, it seems like an `O(N^2)` situation off the bat. - I used a sidechannel from DrawItems, I'm open to other ideas here. - I haven't tested message passing, many of the test failures for listview at the moment look like sequencing errors for messages. I didn't look into it. - The auto mode on Windows 10 looks quite sophisticated, in that it examines many (all) items before deciding the best size. I haven't done anything interesting for auto size mode. - Not really interesting, but the tabs vs spaces situation in this file is a mess. Next Steps ========== - ~~Test with image lists loaded as well~~ - Test properly in Linux - Hope for feedback here (particularly for messages) - Think about auto sizing. If Merged ========= Now that I have a pretty good grasp of how this component works and lays things out, once this is merged I'll see if I can do Groups as well.

[PATCH v8 0/10] MR10192: kernelbase: Handle \\?\ prefix in GetLongPathNameW
by Vishnunithyasoundhar S (＠svishnunithyasoundhar) Feb. 26, 2026

Feb. 26, 2026

The current implementation of GetLongPathNameW triggers a FIXME and returns the original path when it encounters a UNC prefix. While true network UNC paths remain unimplemented, this change allows extended-length local paths (starting with \\?\) to be resolved by stripping the prefix and processing the underlying local path. This fixes issues where applications (such as xalia) passing absolute paths with the extended-length prefix would fail to receive a normalized or resolved long path. ``` 881.036:00d4:00d8:fixme:file:GetLongPathNameW UNC pathname L"\\\\?\\Z:\\home\\vishnunithyasoundhars\\.steam\\debian-installation\\compatibilitytools.d\\debug_build\\files\\share\\wine/../xalia/xalia.exe" ``` Tested: After change with added debug log ``` 22272.558:00d4:00d8:fixme:file:GetLongPathNameW DEBUG: Success!
