v0.0.1-rc.10 Customize frame click behavior and customizable frame renderer

Release Notes - v0.0.1-rc.10 (since v0.0.1-rc.9)

✨ New Features

• Horizontal-only frame expansion - New EXPAND_FRAME click action that expands frames horizontally while keeping vertical position (165c3ad)

  • FOCUS_FRAME: Single click highlights, double click zooms

    var flamegraphView = new FlamegraphView<MyNode>();
    // This is the default, no need to set explicitly
    flamegraphView.setFrameClickAction(FlamegraphView.FrameClickAction.FOCUS_FRAME);

  • EXPAND_FRAME (new): Single click expands frame horizontally (keeps vertical position)

    var flamegraphView = new FlamegraphView<MyNode>();
    flamegraphView.setFrameClickAction(FlamegraphView.FrameClickAction.EXPAND_FRAME);

• Exposed FrameRenderer interface - Allows custom frame rendering implementations (214151d)
  Set the renderer via flamegraphView.setFrameRender(renderer).

  • Support for rounded rectangle frame shapes - DefaultFrameRenderer (cbe574f)

    var renderer = new DefaultFrameRenderer<>(
            frameTextsProvider,
            frameColorProvider,
            frameFontProvider
    );
    renderer.setRoundedFrame(true);

  • For fully custom shapes, implement FrameRenderer and override reusableFrameShape():

    public class CustomShapeRenderer<T> implements FrameRenderer<T> {
        @Override
        public RectangularShape reusableFrameShape() {
            return new RoundRectangle2D.Double(0, 0, 0, 0, 10, 10); // custom arc
        }
        // ... other methods
    }

🐛 Bug Fixes

• Fixed void space when focusing on edge frames - Added proper clamping to prevent scrolling beyond canvas bounds (a21d51c)
• Fixed EDT violation when zooming (538759b)
• Fixed choppy scrolling - Debounced sibling frame computation for smoother performance (2cd292c)
• Fixed frame alignment in mode switch & expand/shrink (9e878f9)
• Fixed horizontal scrollbar visibility on zoom (ed91e3a)
• Fixed expand reset behavior for frames having viewport width (e298544)
• Fixed zoom animation anchor in expand mode (241c3fa)
• Fixed resize loop - Rare case in Flamegraph mode when resizing (81751af)
• Fixed reset zoom when clicking on same zoomed frame (eee6360)

📝 Deprecations

• setRenderConfiguration is deprecated - Use setFrameRender(new DefaultFrameRenderer<>(...)) instead (8922190)

  • Before (deprecated):

    var flamegraphView = new FlamegraphView<MyNode>();
    flamegraphView.setRenderConfiguration(
            FrameTextsProvider.of(frame -> frame.actualNode.toString()),
            FrameColorProvider.defaultColorProvider(f -> Color.BLUE),
            FrameFontProvider.defaultFontProvider()
    );

  • After (new):

    var flamegraphView = new FlamegraphView<MyNode>();
    flamegraphView.setFrameRender(
            new DefaultFrameRenderer<>(
                    FrameTextsProvider.of(frame -> frame.actualNode.toString()),
                    FrameColorProvider.defaultColorProvider(f -> Color.BLUE),
                    FrameFontProvider.defaultFontProvider()
            )
    );

  • The new API exposes the FrameRenderer interface, allowing custom frame rendering implementations beyond DefaultFrameRenderer.

  • Related deprecated methods on FlamegraphView: setFrameColorProvider, setFrameFontProvider, setFrameTextsProvider, setFrameGapEnabled and their getters. These now live on DefaultFrameRenderer directly.

🎨 UI Improvements

• Minimap now positioned at top in flamegraph mode (4b9dd76)
• Disabled dimming of non-focused flames by default (825b652)

🏗️ Infrastructure

• Upgraded to Gradle 9.2.1
• Migrated to nmcp plugin for Maven Central publishing (jreleaser was leaking too many libs)
• Snapshots now published to new Maven Central Portal: https://central.sonatype.com/repository/maven-snapshots/
• Many dependency updates
