# Maneuver Dialog Implementation Progress

## Overview

Implementing a comprehensive modal dialog for creating, editing, and managing spacecraft maneuvers with real-time orbital preview and Hohmann transfer calculations. The dialog provides an intuitive interface for planning orbital maneuvers with immediate visual feedback.

## Completed Tasks

### Phase 1: Foundation (Complete)
- [x] Add ManeuverDialogState to ui_renderer.h
- [x] Extend UIState with maneuver_dialog field
- [x] Add maneuver_list_active and maneuver_list_scroll to UIState
- [x] Create render_maneuver_dialog() skeleton
- [x] Add tab bar widget
- [x] Test dialog open/close with "Create Maneuver" button

**Commit:** `9c55c7c` - feat: Implement maneuver dialog Create tab (Phase 2)
- Implemented complete Create tab workflow for maneuver management dialog
- All Phase 1 foundation work included in this commit
- Dialog opens/closes from maneuver list button

### Phase 2: Create Tab (Complete)
- [x] Implement render_maneuver_create_tab() skeleton
- [x] Add all input widgets (spacecraft, name, direction, delta-v, triggers)
- [x] Implement update_orbital_preview() using preview_burn_result()
- [x] Implement render_orbital_preview() to display results
- [x] Add validation logic with validate_burn_parameters()
- [x] Implement create_maneuver_from_dialog() using add_maneuver_to_simulation()
- [x] Test create workflow end-to-end

**Commit:** `9c55c7c` - feat: Implement maneuver dialog Create tab (Phase 2)
- Complete Create tab workflow with all input widgets
- Real-time orbital preview with color-coded validation
- Integration with add_maneuver_to_simulation()

**Supporting Commit:** `5ecd880` - feat: Add maneuver UI control functions
- add_maneuver_to_simulation(): Add maneuvers dynamically
- preview_burn_result(): Preview orbital elements after burn
- validate_burn_parameters(): Validate burn parameters
- calculate_hohmann_transfer(): Calculate optimal two-burn transfer

### Phase 3: Hohmann Tab (Complete)
- [x] Implement render_maneuver_hohmann_tab() skeleton
- [x] Add body selector widgets
- [x] Implement calculate_hohmann_for_dialog() using calculate_hohmann_transfer()
- [x] Display Hohmann results
- [x] Implement create_hohmann_burns() to add both maneuvers
- [x] Test Hohmann workflow

**Commit:** `94a7dcb` - feat: Implement Hohmann Transfer tab (Phase 3)
- Complete Hohmann transfer workflow with body selection UI
- Auto-generated maneuver names for both burns
- Real-time calculation and display of transfer parameters

### Bug Fixes (Complete)
- [x] Fix segfault at ui_renderer.cpp:503
- [x] Fix widget type for input boxes (GuiValueBoxFloat)
- [x] Add conditional rendering for dropdowns

**Commit:** `351f647` - fix: Initialize UIState maneuver_dialog fields properly
- Fixed segfault by proper initialization of all ManeuverDialogState fields
- Dialog now opens and runs without crashing

**Commit:** `2874c5e` - feat: Add auto-generated maneuver names with edit capability
- generate_maneuver_name() creates sensible names automatically
- User can still manually edit names if desired

**Commit:** `f45b111` - fix: Add conditional rendering for GUI dropdowns
- Wrapped GuiDropdownBox calls with validity checks
- Dropdowns only appear when spacecraft is properly selected

## In Progress

None currently

## Pending Tasks

### Phase 4: Edit Tab
- [ ] Implement render_maneuver_edit_tab() skeleton
- [ ] Load existing maneuver data into fields
- [ ] Lock spacecraft field
- [ ] Implement update_maneuver_from_dialog()
- [ ] Add delete confirmation dialog
- [ ] Test edit and delete workflows

### Phase 5: Enhanced Maneuver List
- [ ] Modify render_maneuver_list_ui() for selectable items
- [ ] Add maneuver preview panel to list
- [ ] Add action buttons (Create, Hohmann, Edit, Delete)
- [ ] Connect buttons to dialog
- [ ] Test enhanced list interaction

### Phase 6: Polish
- [ ] Add keyboard shortcuts (Enter to confirm, Escape to cancel)
- [ ] Improve error messages
- [ ] Add tooltips for complex fields
- [ ] Handle all edge cases
- [ ] Test with various configurations
