From a2f8df6de133a752bd9a0a4f13731fa56112eced Mon Sep 17 00:00:00 2001 From: "sam.peng" Date: Thu, 12 Mar 2026 15:28:12 +0800 Subject: [PATCH 01/16] Add solution, demo, tests, and build infra for WTG WinForms Introduced WTGWinforms.sln with main, demo, and test projects. Added Demo app showcasing legacy WinForms controls (DataGrid, Menu, ToolBar, StatusBar, TreeView, etc.). Added System.Windows.Forms.Tests with comprehensive NUnit test suites for menu/window sizing, owner-draw, context menus, tooltips, DPI, and legacy behaviors. Added missing TreeNode.ContextMenu property for compatibility. Updated build infrastructure: Build.xml, DeploymentSetup.ps1, and isolated Demo build props/targets. Added/updated package references for NUnit, analyzers, coverlet, and bumped repo version to 0.0.25. Enabled NuGet packaging for System.Windows.Forms and set output to Bin folder. Ensured extensive demo and regression test coverage for WiseTech Global's WinForms fork. --- Build.xml | 17 + Demo/Demo.csproj | 24 ++ Demo/Directory.Build.props | 3 + Demo/Directory.Build.targets | 3 + Demo/Form1.Designer.cs | 264 ++++++++++++ Demo/Form1.cs | 394 ++++++++++++++++++ Demo/OwnerDrawMenuItem.cs | 109 +++++ Demo/Program.cs | 38 ++ DeploymentSetup.ps1 | 35 ++ Directory.Packages.props | 4 + .../AdjustWindowRectTests.cs | 185 ++++++++ .../MainMenuTests.cs | 148 +++++++ .../MenuItemTests.cs | 139 ++++++ .../MenuSizeCalculationTests.cs | 299 +++++++++++++ .../MouseOperations.cs | 24 ++ .../System.Windows.Forms.Tests.csproj | 31 ++ .../TabControlTests.cs | 48 +++ .../ToolBarToolTipTests.cs | 258 ++++++++++++ .../TreeNodeTests.cs | 139 ++++++ .../TreeViewTests.cs | 94 +++++ WTGWinforms.sln | 201 +++++++++ eng/Versions.props | 8 +- ...ndows.Forms.PrivateSourceGenerators.csproj | 6 + .../System.Windows.Forms.csproj | 18 + .../TreeView/TreeNode.TreeNodeImageIndexer.cs | 6 + 25 files changed, 2493 insertions(+), 2 deletions(-) create mode 100644 Build.xml create mode 100644 Demo/Demo.csproj create mode 100644 Demo/Directory.Build.props create mode 100644 Demo/Directory.Build.targets create mode 100644 Demo/Form1.Designer.cs create mode 100644 Demo/Form1.cs create mode 100644 Demo/OwnerDrawMenuItem.cs create mode 100644 Demo/Program.cs create mode 100644 DeploymentSetup.ps1 create mode 100644 Tests/System.Windows.Forms.Tests/AdjustWindowRectTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/MainMenuTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/MenuItemTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/MenuSizeCalculationTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/MouseOperations.cs create mode 100644 Tests/System.Windows.Forms.Tests/System.Windows.Forms.Tests.csproj create mode 100644 Tests/System.Windows.Forms.Tests/TabControlTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/ToolBarToolTipTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/TreeNodeTests.cs create mode 100644 Tests/System.Windows.Forms.Tests/TreeViewTests.cs create mode 100644 WTGWinforms.sln diff --git a/Build.xml b/Build.xml new file mode 100644 index 00000000000..8c48cb676ef --- /dev/null +++ b/Build.xml @@ -0,0 +1,17 @@ + + + + + + + powershell.exe -ExecutionPolicy Bypass .\DeploymentSetup.ps1 + + + + + + + + + + \ No newline at end of file diff --git a/Demo/Demo.csproj b/Demo/Demo.csproj new file mode 100644 index 00000000000..ceb13edac8b --- /dev/null +++ b/Demo/Demo.csproj @@ -0,0 +1,24 @@ + + + + WinExe + net10.0-windows;net48 + enable + preview + enable + $(NoWarn);SA1400;CS0649;WFDEV006;NU1602 + + + + true + + + + false + + + + + + + \ No newline at end of file diff --git a/Demo/Directory.Build.props b/Demo/Directory.Build.props new file mode 100644 index 00000000000..9cffb09dc68 --- /dev/null +++ b/Demo/Directory.Build.props @@ -0,0 +1,3 @@ + + + \ No newline at end of file diff --git a/Demo/Directory.Build.targets b/Demo/Directory.Build.targets new file mode 100644 index 00000000000..9cffb09dc68 --- /dev/null +++ b/Demo/Directory.Build.targets @@ -0,0 +1,3 @@ + + + \ No newline at end of file diff --git a/Demo/Form1.Designer.cs b/Demo/Form1.Designer.cs new file mode 100644 index 00000000000..e7e66aa1aff --- /dev/null +++ b/Demo/Form1.Designer.cs @@ -0,0 +1,264 @@ +using System.Drawing;

Remove all NUnit-specific attributes, packages, and usings. Add xUnit as a global using and update test project configuration to use xUnit for test discovery and execution.

They contained state, rendering behavior, event wiring, message processing, layout logic, interop, and designer-facing metadata. + +## Current State In This Repository + +The current repository contains the old surface area under: + +`src/System.Windows.Forms/System/Windows/Forms/Controls/Unsupported/` + +The families currently present are: + +- `ContextMenu/` +- `DataGrid/` +- `MainMenu/` +- `StatusBar/` +- `ToolBar/` + +The implementation model is documented in `src/System.Windows.Forms/System/Windows/Forms/Controls/Unsupported/readme.md`. + +That readme is explicit about the intent: + +- the types exist for binary compatibility +- they are not intended to be executed +- constructors throw `PlatformNotSupportedException` +- non-void members typically `throw null` +- void members do nothing +- inherited members are only reintroduced where metadata requires it + +This means the current code is designed to let old assemblies load, not to let old controls work. + +## Evidence That The Current Surface Is Hollow + +Representative examples in this repository: + +- `ContextMenu` throws from both public constructors and exposes no real event or display behavior. +- `DataGrid` throws from its constructor and exposes a large metadata-shaped surface with inert getters, setters, and events. +- `MainMenu`, `StatusBar`, and `ToolBar` follow the same pattern. +- `Obsoletions.cs` marks these APIs as binary compatibility only and points developers to modern replacements. + +There are also important host integration gaps: + +- `Control.ContextMenu` is currently just a compatibility property/event shell. +- `Form.Menu` and `Form.MergedMenu` are currently compatibility properties, not real menu plumbing. + +That difference matters more than the type definitions themselves. Even if the legacy controls were fully implemented, they would still not behave correctly until the owning `Control` and `Form` integration was restored. + +## Gap Versus The 3.0 Implementation + +The divergence from the 3.0 implementation is large, not cosmetic. + +Two representative comparisons: + +- `ContextMenu.cs`: the current shim is roughly a few dozen lines of metadata and throwing members, while the 3.0 implementation contained full popup, collapse, RTL, command-key, and rendering behavior. +- `DataGrid.cs`: a direct no-index diff against the upstream 3.0 file shows that the current version removes roughly ten thousand lines of implementation logic. + +This is the central architectural fact for any recovery plan: + +> We are not missing a few handlers or a few constructors. We are missing the actual control implementations. + +## Why The Existing Unsupported Folder Should Not Be Evolved In Place + +The local `Unsupported/readme.md` says the folder should not be modified. Even without that warning, the current design makes it a poor place to grow real support: + +- the code structure is intentionally metadata-first, not behavior-first +- the nullability mode is intentionally disabled for compatibility +- members are shaped to preserve reflection and JIT behavior, not runtime semantics +- the folder encodes an explicit product position: load old binaries, do not support the controls + +If the business requirement has changed from compatibility to support, that change should be reflected in the architecture instead of slowly weakening the shim model. + +## Recommended Strategy + +If actual support is required, use this strategy. + +### 1. Decide The Support Contract First + +Be explicit about which of these is required: + +- binary compatibility only +- runtime support for legacy applications +- designer support +- accessibility parity with current WinForms expectations +- long-term supported public API, or temporary migration bridge + +Without this decision, the implementation will drift between two incompatible goals. + +### 2. Treat `release/3.0` As The Behavioral Source Of Truth + +Use the upstream `release/3.0` implementation as the starting point for behavior, not the current `Unsupported` folder. + +That means importing or porting the 3.0 versions of: + +- `ContextMenu`, `Menu`, `MenuItem`, `MainMenu` +- `DataGrid` and its dependent types +- `StatusBar` and panel/event types +- `ToolBar` and button/event types + +The current shim files are still useful as a quick inventory of required public API and obsoletion metadata, but they are not a viable base for runtime work. + +### 3. Restore Host Integration At The Same Time + +Do not port the controls in isolation. The owning framework types must be wired back up in the same effort. + +At minimum this includes: + +- `Control.ContextMenu` +- `Control.ContextMenuChanged` +- `Control.OnContextMenuChanged` +- `Form.Menu` +- `Form.MergedMenu` +- `Form.MenuStart` +- `Form.MenuComplete` +- menu handle update logic and message processing paths that interact with legacy menus + +The upstream 3.0 branch already shows these members participating in runtime behavior. In this repository they are currently compatibility shells. + +### 4. Port By Control Family, Not By Individual File + +The safest sequence is: + +1. Menu stack: `Menu`, `MenuItem`, `ContextMenu`, `MainMenu`, plus `Control` and `Form` integration. +2. `StatusBar` family. +3. `ToolBar` family. +4. `DataGrid` family. + +This order is deliberate: + +- the menu stack has the smallest conceptual surface and exposes whether host integration is correct +- `StatusBar` and `ToolBar` are self-contained compared to `DataGrid` +- `DataGrid` is the highest-risk port because of its size, layout logic, binding behavior, and accessibility implications + +### 5. Preserve Public Shape, Reevaluate Product Semantics + +Once a family becomes truly supported, revisit whether these should still: + +- throw `PlatformNotSupportedException` +- remain hidden with `EditorBrowsable(Never)` +- remain marked with the current `WFDEV006` guidance +- remain described as binary compatibility only in docs and package metadata + +If the runtime behavior is restored but the warnings still tell users not to use the types, the product story becomes internally inconsistent. + +## Expected Porting Work + +Porting the 3.0 code is not a straight file copy. Expect adaptation work in these areas. + +### API And Type System Drift + +- current repository coding style is significantly newer than the 3.0 code style +- nullable reference types have evolved, but the legacy surface intentionally disables nullability in some areas +- helper APIs, interop wrappers, and internal utility names may have changed + +### Rendering And Platform Drift + +- current WinForms code has moved on in DPI handling, theming, and message processing +- any imported rendering path must be checked against the current visual style and DPI model +- old controls may assume older system metrics or menu handle behavior + +### Accessibility + +The original reason for removing these controls was not arbitrary. They lagged in accessibility and modern platform expectations. + +If support is required, decide whether the target is: + +- strict behavioral restoration of 3.0 behavior, or +- restoration plus modern accessibility fixes + +That is a product decision, not just an implementation detail. + +### Designer And Serialization + +Many of these types carry designer attributes and serializer-facing metadata. Runtime support without designer validation is incomplete for many WinForms applications. + +At minimum, validate: + +- designer load behavior +- property grid visibility and serialization +- event hookup serialization +- resource serialization +- form/menu merge scenarios + +### DataGrid Complexity + +`DataGrid` is the hardest family by far. + +Reasons: + +- very large implementation footprint +- custom layout and painting +- binding manager interactions +- editing service interactions +- accessibility subtypes +- table and column style object graph + +If schedule is tight, `DataGrid` should be scoped separately from the menu, `StatusBar`, and `ToolBar` work. + +## Suggested Execution Plan + +## Execution Checklist + +### Phase 1: Menu Stack + +- [x] Restore `release/3.0` `Menu.cs`

This includes cell/row rendering, editing, navigation, hit testing, accessibility, column/table style management, and event handling. Internal painting, layout, tooltip, and accessibility classes are added. Demo forms and designer code showcase DataGrid features. Legacy compat helpers and tracing switches are introduced. Comprehensive unit tests verify functionality. Obsolete HitTestInfo/HitTestType are removed. All new code is MIT licensed and pragma warnings are updated. --- Demo/DataGridForm.Designer.cs | 201 + Demo/DataGridForm.cs | 305 + Demo/Demo.csproj | 6 + Demo/Form1.Designer.cs | 111 - Demo/Form1.cs
