From 4ce95694549f4e7f4be3d79c814776cc53fce0c4 Mon Sep 17 00:00:00 2001 From: tylerjenningsw Date: Tue, 13 Oct 2026 10:52:40 -0400 Subject: [PATCH] Timeline: parent and matte selected layers together (#1260) On a selected layer's row, the Parent menu and pick whip and the Track Matte menu now set every selected layer's parent or matte, as moving a selected layer's bar moves them all; on an unselected row they set that layer's alone. Each is one undo step. A selected layer chosen as the parent or the matte is left out of the layers it links, and parenting that would make a loop is refused as a whole. A new matte layer keeps each layer's mode (layer.setTrackMatte with kind: preserve); a mode and No Track Matte apply to all of them. The Track Matte column gets a pick whip, like the parent's (timeline.layer..trackMattePickWhip, with a translated tooltip): dropped on an audio-video layer's row, it makes that layer the matte. The layers a parent or matte pick whip links are taken when its drag starts. Tests (ui_batch_links): the Parent menu and pick whip, and the Track Matte menu, mode, No Track Matte and pick whip, with real clicks and drags: selected layers change together and unselected ones don't, modes are kept, one undo puts links, compensated transforms and the matte's visibility back, and a refused cycle changes nothing. Both fail on main. --- crates/ui-egui/src/i18n/ui.rs | 7 ++ crates/ui-egui/src/panels/timeline.rs | 81 +++++++++---- crates/ui-egui/tests/ui_batch_links.rs | 154 +++++++++++++++++++++++++ docs/agents.md | 7 ++ 4 files changed, 228 insertions(+), 21 deletions(-) create mode 100644 crates/ui-egui/tests/ui_batch_links.rs diff --git a/crates/ui-egui/src/i18n/ui.rs b/crates/ui-egui/src/i18n/ui.rs index 3a4dd4aff..d56e0de77 100644 --- a/crates/ui-egui/src/i18n/ui.rs +++ b/crates/ui-egui/src/i18n/ui.rs @@ -383,6 +383,7 @@ const JAPANESE: &[(&str, &str)] = &[ ("Overlay", "オーバーレイ"), ("Parameter Name:", "パラメーター名:"), ("Parent pick whip: drag onto a layer", "親ピックウィップ：レイヤー上にドラッグ"), + ("Track Matte pick whip: drag onto a layer", "トラックマットピックウィップ：レイヤー上にドラッグ"), ("Pixel Aspect Ratio:", "ピクセルアスペクト比:"), ("Playing on Video Preview", "ビデオプレビューで再生中"), ("Post-Render Action: {}", "レンダリング後の処理：{}"), @@ -924,6 +925,7 @@ const SIMPLIFIED_CHINESE: &[(&str, &str)] = &[ ("Overlay", "叠加"), ("Parameter Name:", "参数名称："), ("Parent pick whip: drag onto a layer", "父级拾取器：拖到图层上"), + ("Track Matte pick whip: drag onto a layer", "轨道遮罩拾取器：拖到图层上"), ("Pixel Aspect Ratio:", "像素长宽比："), ("Playing on Video Preview", "在视频预览中播放"), ("Post-Render Action: {}", "渲染后动作：{}"), @@ -1656,6 +1658,7 @@ const TRADITIONAL_CHINESE: &[(&str, &str)] = &[ ("Overlay", "疊加"), ("Parameter Name:", "參數名稱："), ("Parent pick whip: drag onto a layer", "上層拾取線：拖到圖層上"), + ("Track Matte pick whip: drag onto a layer", "軌道遮罩拾取線：拖到圖層上"), ("Pixel Aspect Ratio:", "像素長寬比例："), ("Playing on Video Preview", "在視訊預覽中播放"), ("Post-Render Action: {}", "算圖後動作：{}"), @@ -2397,6 +2400,7 @@ const UKRAINIAN: &[(&str, &str)] = &[ ("Overlay", "Накладання"), ("Parameter Name:", "Назва параметра:"), ("Parent pick whip: drag onto a layer", "Зв’язування батьківського шару: перетягніть на шар"), + ("Track Matte pick whip: drag onto a layer", "Зв’язування трекової маски: перетягніть на шар"), ("Pixel Aspect Ratio:", "Пропорції пікселя:"), ("Playing on Video Preview", "Відтворення на відеоперегляді"), ("Post-Render Action: {}", "Дія після рендерингу: {}"), @@ -2942,6 +2946,7 @@ const PORTUGUESE: &[(&str, &str)] = &[ ("Output To:", "Saída para:"), ("Parameter Name:", "Nome do parâmetro:"), ("Parent pick whip: drag onto a layer", "Pick whip de pai: arraste até uma camada"), + ("Track Matte pick whip: drag onto a layer", "Pick whip de track matte: arraste até uma camada"), ("Pixel Aspect Ratio:", "Proporção de pixel:"), ("Playing on Video Preview", "Reproduzindo na visualização de vídeo"), ("Post-Render Action: {}", "Ação pós-renderização: {}"), @@ -3393,6 +3398,7 @@ const CZECH: &[(&str, &str)] = &[ ("Overlay", "Překrytí"), ("Parameter Name:", "Název parametru:"), ("Parent pick whip: drag onto a layer", "Propojovací nástroj nadřazené vrstvy: přetáhněte na vrstvu"), + ("Track Matte pick whip: drag onto a layer", "Propojovací nástroj masky stopy: přetáhněte na vrstvu"), ("Pixel Aspect Ratio:", "Poměr stran pixelů:"), ("Playing on Video Preview", "Přehrávání ve videonáhledu"), ("Post-Render Action: {}", "Akce po vykreslení: {}"), @@ -3949,6 +3955,7 @@ const SPANISH: &[(&str, &str)] = &[ ("Overlay", "Superposición"), ("Parameter Name:", "Nombre del parámetro:"), ("Parent pick whip: drag onto a layer", "Selector de capa padre: arrastra hasta una capa"), + ("Track Matte pick whip: drag onto a layer", "Selector de mate de seguimiento: arrastra hasta una capa"), ("Pixel Aspect Ratio:", "Relación de aspecto de píxel:"), ("Playing on Video Preview", "Reproduciendo en la previsualización de vídeo"), ("Post-Render Action: {}", "Acción posterior al procesamiento: {}"), diff --git a/crates/ui-egui/src/panels/timeline.rs b/crates/ui-egui/src/panels/timeline.rs index 163e6507d..f2d91fa3d 100644 --- a/crates/ui-egui/src/panels/timeline.rs +++ b/crates/ui-egui/src/panels/timeline.rs @@ -155,16 +155,29 @@ fn with_expr_rows(rows: Vec, comp: &Comp, tl: &crate::state::TimelineState, } /// A pick-whip drag in progress: (kind, layer, prop uid, start point).
