From 660694f00f091005e0f72b77121228038203036b Mon Sep 17 00:00:00 2001 From: Halit Can Date: Sun, 12 Jul 2026 02:05:31 +0300 Subject: [PATCH] Refactor styles and implement new canvas viewport - Updated styles in `styles.rs` to include new pane and canvas backgrounds, while marking unused functions with `#[allow(dead_code)]`. - Modified `text_editor.rs` to suppress warnings for unused function parameters. - Enhanced `title_bar.rs` to create a unified title/menu bar with improved hover states and draggable functionality. - Simplified `sidebar.rs` to always use a single-column layout and improved tool button styling with hover feedback. - Added a new `viewport.rs` file to implement a custom canvas viewport widget for zoom and pan rendering, replacing the previous layout-based approach. - Updated theme management in `theme.rs` to suppress warnings for unused methods. - Adjusted line count report to reflect recent changes in codebase. --- .../plans/1783771837559-curious-river.md | 397 +++++----- Cargo.lock | 61 ++ Cargo.toml | 2 +- countlines.sh | 2 +- hcie-iced-app/crates/hcie-iced-gui/Cargo.toml | 1 + hcie-iced-app/crates/hcie-iced-gui/src/app.rs | 610 ++++++++++----- .../crates/hcie-iced-gui/src/canvas/mod.rs | 700 ++++++++++++++++-- .../hcie-iced-gui/src/canvas/viewport.rs | 240 ++++++ .../hcie-iced-gui/src/dialogs/new_image.rs | 31 +- .../crates/hcie-iced-gui/src/dock/state.rs | 108 +-- .../crates/hcie-iced-gui/src/dock/view.rs | 266 +++++-- .../crates/hcie-iced-gui/src/io/clipboard.rs | 1 + .../crates/hcie-iced-gui/src/io/tablet.rs | 8 + .../crates/hcie-iced-gui/src/main.rs | 5 +- .../src/panels/ai_script_panel.rs | 1 + .../hcie-iced-gui/src/panels/brushes.rs | 342 +++++++-- .../crates/hcie-iced-gui/src/panels/menus.rs | 146 ++-- .../crates/hcie-iced-gui/src/panels/styles.rs | 29 +- .../hcie-iced-gui/src/panels/text_editor.rs | 1 + .../hcie-iced-gui/src/panels/title_bar.rs | 173 ++++- .../crates/hcie-iced-gui/src/sidebar/mod.rs | 208 +++--- .../crates/hcie-iced-gui/src/theme.rs | 1 + line_count_report.txt | 18 +- 23 files changed, 2514 insertions(+), 837 deletions(-) create mode 100644 hcie-iced-app/crates/hcie-iced-gui/src/canvas/viewport.rs diff --git a/.mimocode/plans/1783771837559-curious-river.md b/.mimocode/plans/1783771837559-curious-river.md index 5f1576c..19da949 100644 --- a/.mimocode/plans/1783771837559-curious-river.md +++ b/.mimocode/plans/1783771837559-curious-river.md @@ -1,226 +1,217 @@ -# Iced GUI — Photoshop-Style UI Overhaul Plan +# Iced GUI — Remaining Tasks & Reprioritized Plan -## Goal -Transform the iced GUI from a generic dark theme to a professional Photoshop-like appearance with proper toolbox, menus, panels, and window management. +## Current Status + +The iced GUI has ~5000 lines across 33 source files.
