* Remove left margin from window caption label
Delete the hardcoded Inset{left: 100} margin on the caption Label in widgets/src/window.rs so the label can be centered by the parent layout. This cleans up alignment and removes an unnecessary offset in the window header.
* Use window title in caption; format button click
Apply the configured window title to the window caption and make a small UI code cleanup.
- examples/splash: set window.title to "Splash Example" and reformat the tooltip button click check to a multiline expression for readability.
- widgets/src/window.rs: import label::* and update ensure_initialized to copy cx.windows[window_id].create_title into the caption_label when non-empty so the window chrome shows the configured title.
The CalloutTooltip is a fancier wrapper atop Tooltip that allows
the user to display a tooltip with a callout triangle that points
at a particular widget, making it clearer what the tooltip
corresponds to. It also supports a custom text color, background color,
positioning suggestion (top, right, left, bottom), full text wrapping,
and dynamically resize and re-orient itself to fit within the app screen.
* Add macOS video playback support using AVPlayer + CVMetalTextureCache
Extends the Video widget from Android-only to also support macOS with
hardware-accelerated, zero-copy video rendering through Metal. Uses
AVPlayer for decoding and CVMetalTextureCache to map decoded frames
directly to MTLTextures without CPU copies.
Key changes:
- New AppleVideoPlayer module (AVPlayer + CVPixelBuffer → MTLTexture pipeline)
- FFI bindings for CVMetalTextureCache, CMTime, and related Apple APIs
- Video frame polling integrated into macOS paint cycle
- TextureFormat::VideoRGB ungated from Android-only to all platforms
- Video widget made cross-platform (TextureHandleReady wait is Android-only)
- Fixed shader aspect ratio bug (&&→|| for non-positive dimension check)
- Added video demo to uizoo and scratchpad examples
