Legacy Control Migration: StatusBar

Status

Migration complete. All nine StatusBar family files have been ported from the upstream source into src/System.Windows.Forms/System/Windows/Forms/Controls/Unsupported/StatusBar, force-synced against upstream declarations and documentation, and verified build-clean.

Files ported / changed

File	Change
StatusBar.cs	Working control implementation (layout, simple-text mode, panel realization, owner-draw dispatch, tooltip handling, StatusBarPanelCollection); upstream class summary and constructor doc synced
StatusBarPanel.cs	Working panel implementation (sizing, content measurement, icon handling, owner-draw realization, parent linkage); upstream class summary and explicit default constructor synced
StatusBarDrawItemEventArgs.cs	Working constructors and Panel property; upstream XML docs and license header synced
StatusBarDrawItemEventHandler.cs	Delegate surface; upstream summary and license header synced
StatusBarPanelAutoSize.cs	Real enum; full upstream Spring summary (cross-referencing None and Contents) synced
StatusBarPanelBorderStyle.cs	Real enum; license header synced
StatusBarPanelClickEventArgs.cs	Working constructor and StatusBarPanel property; upstream class and member summaries synced
StatusBarPanelClickEventHandler.cs	Delegate surface; upstream summary and license header synced
StatusBarPanelStyle.cs	Real enum; license header synced

Files deleted

File	Reason
StatusBar.StatusBarPanelCollection.cs	StatusBarPanelCollection implementation now lives inside StatusBar.cs

Resource and metadata parity

Upstream SRDescription attributes restored for StatusBar.cs and StatusBarPanel.cs (Panels, ShowPanels, SizingGrip, DrawItem, PanelClick, and all panel properties). Matching keys added to src/System.Windows.Forms/Resources/SR.resx.

XLF translation parity

15 StatusBar-specific trans-unit entries added to all 13 locale XLF files under src/System.Windows.Forms/Resources/xlf, sourced verbatim from the upstream sibling repository:

StatusBarDrawItem · StatusBarOnPanelClickDescr · StatusBarPanelAlignmentDescr · StatusBarPanelAutoSizeDescr · StatusBarPanelBorderStyleDescr · StatusBarPanelIconDescr · StatusBarPanelMinWidthDescr · StatusBarPanelNameDescr · StatusBarPanelsDescr · StatusBarPanelStyleDescr · StatusBarPanelTextDescr · StatusBarPanelToolTipTextDescr · StatusBarPanelWidthDescr · StatusBarShowPanelsDescr · StatusBarSizingGripDescr

Locales: cs · de · es · fr · it · ja · ko · pl · pt-BR · ru · tr · zh-Hans · zh-Hant

Tests (System.Windows.Forms.Legacy.Tests)

StatusBarTests.cs covers: default property values, StatusBarPanelCollection operations (add, insert, remove, clear, contains, key lookup), panel-mode toggle, ToString(), panel property semantics (alignment, autosize, border style, owner-draw, width, min width, tooltip text), and PanelClick/DrawItem event dispatch.

Demo (System.Windows.Forms.Legacy.Demo)

StatusBarForm.cs / StatusBarForm.Designer.cs exercise panel mode vs. simple-text mode, dynamic panel insertion/removal, sizing-grip toggle, border-style cycling, owner-draw rendering, per-panel tooltips, panel-click logging, and a live clock panel. Main demo launcher updated to open StatusBar directly.

Remaining Work

• Run StatusBar tests in the build environment and confirm they stay green.
• Manually verify owner-draw panels, grip behavior, and border-style transitions.
• Review designer and serialization behavior for StatusBar and StatusBarPanel.
• Verify XLF entries round-trip through the localization build pipeline.
