From faa59f6a3c08bc111837fcffd506572353df7368 Mon Sep 17 00:00:00 2001 From: "Janus C. H. Knudsen" Date: Mon, 6 Oct 2025 21:16:29 +0200 Subject: [PATCH] Improves event layout and stacking logic Refactors the event layout and stacking logic based on review feedback. This includes: - Merging conflicting event groups to prevent inconsistencies. - Implementing minimal stack level assignment using a min-heap. - Consolidating styling and using DateService for drag operations. - Adding reflow after drag and drop. - Improving the column event filtering to include events overlapping midnight. - Ensuring explicit sorting of events for grid layout. --- .workbench/review.txt | 217 +++++++++++++++++++++++++ complexity-output.json | 0 docs/cyclomatic-complexity-report.md | 50 ++++++ scenarios/scenario-1.html | 62 +++++++ scenarios/scenario-10.html | 77 +++++++++ scenarios/scenario-2.html | 61 +++++++ scenarios/scenario-3.html | 69 ++++++++ scenarios/scenario-4.html | 69 ++++++++ scenarios/scenario-5.html | 69 ++++++++ scenarios/scenario-6.html | 69 ++++++++ scenarios/scenario-7.html | 62 +++++++ scenarios/scenario-8.html | 55 +++++++ scenarios/scenario-9.html | 67 ++++++++ scenarios/scenario-styles.css | 162 ++++++++++++++++++ scenarios/scenario-test-runner.js | 152 +++++++++++++++++ src/managers/EventLayoutCoordinator.ts | 120 +++++++++----- src/renderers/EventRenderer.ts | 24 +-- stacking-visualization-new.html | 150 +++++++++++++++++ stacking-visualization.html | 22 +++ 19 files changed, 1502 insertions(+), 55 deletions(-) create mode 100644 .workbench/review.txt create mode 100644 complexity-output.json create mode 100644 docs/cyclomatic-complexity-report.md create mode 100644 scenarios/scenario-1.html create mode 100644 scenarios/scenario-10.html create mode 100644 scenarios/scenario-2.html create mode 100644 scenarios/scenario-3.html create mode 100644 scenarios/scenario-4.html create mode 100644 scenarios/scenario-5.html create mode 100644 scenarios/scenario-6.html create mode 100644 scenarios/scenario-7.html create mode 100644 scenarios/scenario-8.html create mode 100644 scenarios/scenario-9.html create mode 100644 scenarios/scenario-styles.css create mode 100644 scenarios/scenario-test-runner.js create mode 100644 stacking-visualization-new.html diff --git a/.workbench/review.txt b/.workbench/review.txt new file mode 100644 index 0000000..d1a2b5c --- /dev/null +++ b/.workbench/review.txt @@ -0,0 +1,217 @@ +De 6 vigtigste fund (med fixes) + +Gruppering kan “brygge” mellem to grupper uden at merge dem +groupEventsByStartTime finder første eksisterende gruppe med konflikt og lægger eventet deri.

Event Stacking & Grid Layout - Test Scenarios

+ +
+

About This Test Suite

+

+ This test suite validates the event layout algorithm for the Calendar Plantempus application. + The algorithm determines how overlapping events should be rendered using two strategies: +

+
    +
  • GRID Layout: Events that start within a threshold (±30 minutes) are placed in a grid container where they can share columns
    • +
  • STACKED Layout: Events are stacked with horizontal offsets (15px per level)
    • +
+

+ Each scenario tests a specific edge case or layout pattern. Click on a scenario below to view the visual representation and test results. +

+
+ +
+
+

Scenario 1: No Overlap

+

Three sequential events with no time overlap. All should have stack level 0.

+ View Test → +
+ +
+

Scenario 2: Column Sharing (Grid)

+

Two events starting at same time (10:00) - should share columns in a grid with 2 columns.

+ View Test → +
+ +
+

Scenario 3: Nested Stacking

+

Events with progressive nesting: A contains B, B contains C, C and D overlap. Tests stack level calculation.

+ View Test → +
+ +
+

Scenario 4: Complex Stacking

+

Long event (A) with multiple shorter events (B, C, D) nested inside at different times.

+ View Test → +
+ +
+

Scenario 5: Three Column Share

+

Three events all starting at 10:00 - should create a 3-column grid layout.

+ View Test → +
+ +
+

Scenario 6: Overlapping Pairs

+

Two separate pairs of overlapping events. Each pair should be independent.

+ View Test → +
+ +
+

Scenario 7: Long Event Container

+

One long event (A) containing two shorter events (B, C) that don't overlap each other.

+ View Test → +
+ +
+

Scenario 8: Edge-Adjacent Events

+

Events that touch but don't overlap (A ends when B starts). Should not stack.

+ View Test → +
+ +
+

Scenario 9: End-to-Start Chain

+

Events linked by end-to-start conflicts within threshold. Tests conflict chain detection.

+ View Test → +
+ +
+

Scenario 10: Four Column Grid

+

Four events all starting at same time - maximum column sharing test.
