From 641a0a599c6e9b770b058ab7f1b925813c55bbad Mon Sep 17 00:00:00 2001 From: Tig Date: Wed, 3 Dec 2025 16:30:22 -0700 Subject: [PATCH] Optimize View drawing logic and update ClearViewport tests Refactored the `View` class to include a `NeedsDraw` check in multiple drawing methods, improving rendering efficiency. Adjusted `OnDrewText` and `DrewText` event handling for consistency. Removed unused code and redundant tests. Rewrote and reorganized `ClearViewportTests` for clarity and compatibility with the new `NeedsDraw` logic. Added new tests to validate `ClearViewport` behavior under various conditions, including transparent viewports, event cancellations, and content-only clearing. Updated namespaces for better alignment, disabled a noisy `ComboBoxTests` test, and improved code formatting and maintainability across files. --- Terminal.Gui/ViewBase/View.Drawing.cs | 14 +-- Tests/UnitTests/Views/ComboBoxTests.cs | 2 +- .../Lines/StraightLineExtensionsTests.cs | 2 +- .../ViewBase}/Draw/ClearViewportTests.cs | 88 +++++++++++-------- .../Draw/ViewDrawTextAndLineCanvasTests.cs | 28 ------ 5 files changed, 60 insertions(+), 74 deletions(-) rename Tests/{UnitTests/View => UnitTestsParallelizable/ViewBase}/Draw/ClearViewportTests.cs (78%) diff --git a/Terminal.Gui/ViewBase/View.Drawing.cs b/Terminal.Gui/ViewBase/View.Drawing.cs index a6847a3bb..8df979247 100644 --- a/Terminal.Gui/ViewBase/View.Drawing.cs +++ b/Terminal.Gui/ViewBase/View.Drawing.cs @@ -253,7 +253,7 @@ public partial class View // Drawing APIs if (Margin is { } && Margin.Thickness != Thickness.Empty/* && Margin.ShadowStyle == ShadowStyle.None*/) { - //Margin?.Draw (); + //Margin?.Draw (); } } @@ -288,7 +288,7 @@ public partial class View // Drawing APIs internal void DoClearViewport (DrawContext?
