Raisin.WPF.Base 2.0.0

Raisin.WPF.Base

Shared WPF base library for .NET 8 desktop applications — MVVM foundation, window management, docking layout persistence, data grid behaviors, settings infrastructure, and dark theme support.

Features

MVVM

• ViewModelBase — INotifyPropertyChanged base with SetProperty, batch notification, and UI thread helpers
• ToolWindowViewModel — Base for tabbed/dockable tool windows with title deduplication, visibility tracking, and close support
• RelayCommand — Simple ICommand implementation with CanExecute support

Window management

• WindowPlacementHelper — Capture, restore, and validate window position across monitor configurations
• DarkWindowHelper — Apply Windows 11 dark mode to window chrome (title bar, background) with WM_ERASEBKGND interception to prevent white flash
• DockLayoutHelper — Save and restore AvalonDock layouts to XML with atomic file writes

Data grid

• DataGridColumnBehavior — Attached behavior for auto-fit and persistent column widths with right-click context menu
• AdaptiveHeader — Column headers that switch between full and abbreviated text based on available width
• GridSettingsService — Persists column widths to JSON with in-memory cache

Settings infrastructure

• SettingDefinition — Declarative metadata for settings (category, editor type, bounds, choices)
• SettingItemViewModel hierarchy — Concrete view models for Bool, Int, Double, String, TimeOnly, Choice, IntList, and compound types (Offset, TimePair, IntPair, DoublePair)
• SettingItemFactory — Creates the right view model from a definition
• SettingItemTemplateSelector — WPF DataTemplateSelector for rendering each setting type

Other utilities

• LargeNumberConverter — IValueConverter formatting numbers as 1.5B, 2.3M, 4.7K
• NumericInputBehavior — Attached behavior restricting TextBox input to integers or decimals
