From 62a5dceac1f34c57f05eb8aa1126b80b05c0b59d Mon Sep 17 00:00:00 2001 From: kevin Date: Wed, 19 Aug 2026 15:37:07 +0200 Subject: [PATCH 1/2] Keep the planner and editor panes from clipping their content MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The side panes were sized below the intrinsic width of what they hold, so content was cut off rather than shrinking — the surrounding ScrollViewers deliberately have no horizontal scrolling, so there was nothing to scroll to. - Raise the strand-list and inspector defaults (236/318 -> 260/340) and their splitter minimums to match, in both SecondPage.xaml and its layout code-behind. - Make the squeezed labels trim instead of wrap or overflow: the segment GUID moves from a horizontal StackPanel (which measures with infinite width) into a Grid with a `*` column, and the strand rows get NoWrap + CharacterEllipsis. - Shrink the strand row's fixed cost (padding, swatch, four icon buttons) so a narrow rail still leaves room for the name. - Raise TrainEditor's 2x2 tile trigger to 1400: the trigger only sees the window width, but the tiles get the window minus the train rail, whose MaxWidth drops to 480 here. At the old 1150 each tile was squeezed to ~330px. - Tighten the pill button's padding and drop its MinWidth so two- and three-up pills fit the narrowest pane. Verified: desktop head builds with 0 warnings, 40/40 tests pass. Visuals need a real device, since the Skia surface can't be screenshotted here.

So you must never claim a layout +"looks right" or is visually verified. Reason instead from **measure/arrange semantics** and say +plainly that the maintainer confirms visuals on a real device. + +This makes layout bugs the expensive kind, so be deliberate about the two that keep recurring here: + +- **A `StackPanel` measures its children with infinite width** along its orientation, so content + overflows the pane instead of shrinking. When something must trim to the available width, use a + `Grid` with a `*` column. +- **Text needs `TextWrapping="NoWrap"` with `TextTrimming="CharacterEllipsis"`** to trim; otherwise a + squeezed column breaks it character-by-character. +- The surrounding `ScrollViewer`s deliberately have **no horizontal scrolling**, so anything wider + than its pane is *clipped*, not scrollable. Panes must be sized at or above the intrinsic width of + their content. +- An `AdaptiveTrigger` sees the **window** width, not the width the element actually receives. When a + drag-resizable rail sits beside the content, the threshold must account for the rail's `MaxWidth` — + and those two numbers must be kept in sync deliberately, with a comment saying so. + +## MVVM and structure — enforced + +- CommunityToolkit.Mvvm with **field-based** `[ObservableProperty]` and `[RelayCommand]` + (`MVVMTK0045` partial-property advice is intentionally suppressed). +- **No business logic in pages.** No code-behind beyond `InitializeComponent()` — with exactly two + deliberate exceptions, both the responsive master-detail layout that reacts to width *and* a + selection change, which `AdaptiveTrigger`/`VisualStateManager` cannot express: `Pages/MainPage.xaml.cs` + and `Pages/SecondPage.xaml.cs`. Nothing else lives in either file. (arc42 SC-7 still says one + exception; the code has two.) +- Other interactivity goes through a `Command` binding, or — only when an event must reach a command + that isn't natively `Command`-bindable, such as a tapped `Grid` — an attached behavior in + `Presentation/Behaviors/`. **Reach for a new behavior rather than a `*_Click`/`*_Tapped` handler.** +- **Avoid imperative control APIs** (`ScrollViewer.ChangeView` and similar). Prefer a bound value the + ViewModel owns — the Streckenplaner's zoom is a `SecondViewModel.ZoomFactor` double driving a + `Viewbox`'s bound `Width`/`Height`, not a programmatic zoom call. This is both more MVVM-honest and + necessary, since `ScrollViewer` zoom isn't reliably supported on every Uno target. +- **Folder is `Pages`, never "Screens".** `Components/` = page-specific sections inheriting the page's + `DataContext`; `Widgets/` = reusable atoms exposing `DependencyProperty`s. +- Suffixes: `Presentation/ViewModels/` → `*ViewModel`, `Behaviors/` → `*Behavior`, `Widgets/` → + `*Widget`. (Two existing files break this — `LegendItem.cs`, `StrandGroup.cs` — don't copy them.) +- Converters are registered **once** globally in `Styles/Converters.xaml`; design tokens in + `Styles/DesignTokens.xaml`. Don't re-declare per page. +- Classic `{Binding}` views carry a design-time `d:DataContext="{d:DesignInstance ...}"` with + `mc:Ignorable="d"`. Add one to every new view or data template. +- Routes and ViewMaps in `App.xaml.cs` → `RegisterRoutes` (Uno.Extensions Navigation). +- **One top-level type per file**; namespace matches folder and is file-scoped (`IDE0130`/`IDE0161` + are build errors). + +## Language and platform behaviour + +- **All user-facing text is German** — labels, dialogs, error messages.
