Fennec/NativeUI/Viewport: Difference between revisions

* browser.js must ignore viewport-dependent events (including clicks, double-taps, and viewport updates) from java during the period where the browser content document is different from the browser displayed document. Java may still update its own viewport properties for the compositor's benefit.

* If the viewport size changes, Java must first send a resize notification. browser.js must, upon processing the resize, synchronously notify Java of receiving this event, along with any updated properties (offset, zoom, page size). While processing this event (still on the gecko thread), Java may recalculate properties (offset, zoom, display port margins) and must queue an event back on the gecko thread with the new properties. Drawing must be suppressed between the handling of the initial resize notification and handling of the final property update event.
